Template:Short description Template:Redirect Template:Infobox currency

The baht (Template:IPAc-en; Template:Langx, {{#invoke:IPA|main}}; sign: ฿; code: THB) is the official currency of Thailand. It is divided into 100 satang ({{#invoke:Lang|lang}}, {{#invoke:IPA|main}}). Prior to decimalisation, the baht was divided into eight fueang ({{#invoke:Lang|lang}}, {{#invoke:IPA|main}}), each of eight at ({{#invoke:Lang|lang}}, {{#invoke:IPA|main}}). The issuance of currency is the responsibility of the Bank of Thailand. SWIFT ranked the Thai baht as the 10th-most-frequently used world payment currency as of December 2023.<ref>[1] Template:WebarchiveRMB Tracker February 2019 Template:Webarchive</ref>

</timeline>The Thai baht, like the pound, originated from a traditional unit of mass. Its currency value was originally expressed as that of silver of corresponding weight (now defined as 15 grams), and was in use probably as early as the Sukhothai period in the form of bullet coins known in Thai as photduang.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> These were pieces of solid silver cast to various weights corresponding to a traditional system of units related by simple fractions and multiples, one of which is the baht. These are listed in the following table:<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Though the coins themselves have names like: solot, siao, sik, etc, the formal division of the Thai baht (tical) is 1 baht = 8 fueang = 64 at. This means that one baht is divided into eight fueang, and each one fueang is divided into 8 at. Currently, the Thai baht do not employ the at as a subunit, but the at is the current subunit of the Lao kip.

File:Siamese Pre-Decimal Tical System.png
Siamese predecimal tical system

This predecimal system was in use up until 1897, when the decimal system devised by Prince Jayanta Mongkol, in which one baht = 100 satang, was introduced by his half-brother King Chulalongkorn along with the demonetization of silver bullet coins on 28 October 1904 after the end of silver bullet coin production by the opening of Sitthikarn Royal Mint in 1857.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> However, coins denominated in the old units were issued until 1910, and the amount of 25 satang is still commonly referred to as a {{#invoke:Lang|lang}}, as is the 25-satang coin.

Until 27 November 1902, the baht was fixed on a purely silver basis, with 15 grams of silver to the baht. This caused the value of the currency to vary relative to currencies on a gold standard. From 1856 to 1864, the values of certain foreign silver coins were fixed by law, with 5 baht = 3 Spanish dollar = 7 Indian rupees.<ref name=":9">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Before 1880 the exchange rate was fixed at 8 baht per pound sterling, falling to 10 to the pound during the 1880s.

In 1902, the government began to increase the value of the baht by following all increases in the value of silver against gold but not reducing it when the silver price fell. Beginning at 21.75 baht per pound sterling, the currency rose in value until, in 1908, a fixed peg to the British pound sterling was established of 13 baht per pound. This was revised to 12 baht in 1919 and then, after a period of instability, to 11 baht in 1923. During World War II, the baht was fixed at a value of one Japanese yen on 22 April 1942.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

From 1956 until 1973, the baht was pegged to the US dollar at an exchange rate of 20.8 baht = one dollar and at 20 baht = 1 dollar until 1978.<ref>Template:Cite journal</ref> <ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> A strengthening US economy caused Thailand to re-peg its currency at 25 to the dollar from 1984 until 2 July 1997, when the country was affected by the 1997 Asian financial crisis. The baht was floated and halved in value, reaching its lowest rate of 56 to the dollar in January 1998. It rose to 30 per dollar in January 2021.

The baht was originally known to foreigners by the term tical,<ref name="JSS_033_2c_Campos">Template:Cite journal</ref> which was used in English language text on banknotes until the series 2 1925.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Currency symbolEdit

The currency symbol for the baht is Template:Char (a Latin letter B with a vertical stroke). In 1986, this symbol was given a codepoint for computer use in the Thai Industrial Standard 620-2533 (Thailand's extension of ASCII), at position 0xDF. This national standard was subsequently subsumed into international standards as ISO/IEC 8859-11 ("ISO Latin-Thai"). In turn, the ISO 8859 series were transposed into the Unicode standard,<ref>Template:Cite report</ref> where the symbol was allocated the codepoint Template:Unichar.<ref>Template:Cite book</ref> The symbol is also used for the Panamanian balboa.<ref name="DPD">Template:Cite book</ref>

AbbreviationEdit

In Thai usage, the baht ({{#invoke:Lang|lang}}) is legally abbreviated as {{#invoke:Lang|lang}} according to Section 7 of the Currency Act, B.E. 2501.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

BitcoinEdit

For a time, the baht symbol was appropriated by some as a symbol for Bitcoin, a cryptocurrency. Following representations,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> a separate code point (Template:Unichar, a Latin letter B with two vertical strokes) was allocated in Unicode version 10.0.<ref name="unicode-10">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Square katakanaEdit

Template:Contains special characters In Unicode 1.0, two codepoints were allocated to the baht, one as the currency symbol in the Thai range and one in the CJK Compatibility block as a square version of the Japanese word for "baht", written in katakana script.<ref name="Lunde" /> The CJK codepoint, Template:Unichar, is documented in subsequent versions of the standard as "a mistaken, unused representation" and users are directed to Template:Unichar instead.<ref>Template:Cite book</ref> Consequently, only a few computer fonts have any content for this codepoint and its use is deprecated.<ref name="Lunde">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

(The Japanese for "baht" is {{#invoke:Lang|lang}} (Template:Transliteration). However, the reference glyph Template:Angbr and the character name correspond to {{#invoke:Lang|lang}} (Template:Transliteration, from English "parts").<ref name="Lunde" />)

Historical symbols used before decimalizationEdit

Before decimalization, the Siamese government employed Chinese, Latin, Jawi (Malay), Devanagari, Khmer and Khom, Lanna, and Burmese scripts  in banknotes and coins, as seen. The reason is not clear, though it is a common understanding that it is to ease the facilicitation of trade within Siam. It could also be the case that at the time, the capital, Bangkok (Phra Nakhon) was still a multi-cultural city, so as to be more inclusive, the government added various other language onto the currency – though by the second series after the decimalization in the 1900s, the currency was all but monolingual.

Template:Lang-zh ({{#invoke:Lang|lang}}): This character was use during the times of Rama IV to represent baht, though this was phased out by another character which is in partially and informally used today. The only occurrence of this character was in Rama IV's banknote series.

Template:Lang-zh ({{#invoke:Lang|lang}}): This character was in use from 1868–1925 officially on banknotes to represent baht. It is still in use today unofficially to refer to the Thai baht in general, as in {{#invoke:Lang|lang}} or {{#invoke:Lang|lang}}.

Template:Lang-zh ({{#invoke:Lang|lang}}): This character was in use from 1851–1908 officially on banknotes and coins to represent salueng.

Template:Lang-zh ({{#invoke:Lang|lang}}): This character was in use from 1851–1908 officially on banknotes and coins to represent fueang.

The notation for these Chinese character are written like they are in Thai, though there is a caveat: it is written right to left, as was the convention back then, so one baht is written {{#invoke:Lang|lang}} or {{#invoke:Lang|lang}}, if there are smaller units involved the notation can write like such: {{#invoke:Lang|lang}} for one baht, three salueng, and one fueang.

Photduang coinageEdit

File:Tailandia.jpg
Example of the Spanish dollar which was marked with the Siamese government's emblem – marking that it is legal tender

Cowrie shells from the Mekong River had been used as currency for small amounts since the Sukhothai period. Before 1860, Thailand did not produce coins using modern methods. Instead, a so-called "bullet" coinage was used, consisting of bars of metal, thicker in the middle, bent round to form a complete circle on which identifying marks were stamped.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>Template:Cite book</ref> Denominations issued included Template:Frac, Template:Frac, Template:Frac, Template:Frac, Template:Frac, Template:Frac, 1, Template:Frac, 2, Template:Frac, 4, Template:Frac, 8, 10, 20, 40 and 80 baht in silver and Template:Frac, Template:Frac, Template:Frac, Template:Frac, 1, Template:Frac, 2 and 4 baht in gold. One gold baht was generally worth 16 silver baht. Between 1858 and 1860, foreign trade coins were also stamped by the government for use in Thailand.

Sukhothai and Ayutthaya photduangEdit

Photduang, a form of currency used during the Sukhothai period, was characterized by its longer legs, which created a larger and wider hole in the middle. These coins were primarily made of silver and featured a cut across the front of each leg. This cut served a dual purpose: it authenticated the money and allowed for the quality of the silver to be tested. Over time, as the Sukhothai Kingdom declined and became a vassal state of Ayutthaya—which was established as the capital in 1350—the design of photduang evolved. The coins became rounder with shorter legs, and the central hole, while still present, grew smaller. By the end of this era, the hole disappeared completely. The cuts on the legs also reduced in size and were eventually replaced by a small elliptical nick, known as "Met Kao San," on one side of the coin.<ref name=":02">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Thonburi and Rattanakosin photduangEdit

The Thonburi period (1767–1782) and the Rattanakosin period, beginning in 1782, adopted the photduang design from the late Ayutthaya period. The coins from these periods had no central hole, and the legs were even shorter. A key difference was that

File:Administrative Division of Rattanakosin Kingdom in 1805.jpg
Siam at the time of podduang issue 4 (1805)

Thonburi photduang lacked the elliptical nick, whereas the Rattanakosin coins reintroduced this feature, similar to the Ayutthaya coins. Photduang from these later periods typically featured two stamped marks: the dynasty mark on top and the king's personal mark on the front part. The dynasty mark often symbolized the kingdom's ruling dynasty, while the king's personal mark represented the reigning monarch.<ref name=":02" />

Markings on the photduangEdit

The markings on photduang coins varied across different periods. During the Sukhothai era, some coins bore no marks, while others had up to 11. This variation was because, at that time, individuals and merchants could produce their own money. However, from the Ayutthaya period onward, the production of photduang was monopolized by the government, making it easier to identify coins from each era. Ayutthaya photduang typically bore two marks: the dynasty mark, which could be a spoked wheel symbolizing the "Wheel of Law" from Buddhist teachings or the Chakra (Vishnu's weapon), represented by a pattern of 8 dots surrounding a central dot. The king's personal mark varied with each ruler and included symbols such as a conch shell, a Garuda bird (khrut), an elephant, and an anchor, each symbolizing different aspects of the king's reign or divine associations.<ref name=":02" />

Predecimal coinageEdit

Rama III (1824–1851) was the first king to consider the use of a flat coin. He did so not for the convenience of traders, but because he was disturbed that the creatures living in the cowrie shells were killed. When he learned of the use of flat copper coins in Singapore in 1835, he contacted a Scottish trader, who had two types of experimental coins struck in England. The king rejected both designs. The name of the country put on these first coins was Muang Thai, not Siam.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

In 1860, modern-style coins were introduced. These were silver 1 sik; 1 fueang; 1 and 2 salueng; 1, 2, and 4 baht; with the baht weighing 15.244 grams and the others weight-related. Tin 1 solot and 1 at followed in 1862, with gold Template:Frac, 4, and 8 baht introduced in 1863 and copper 2 and 4 at in 1865. Copper replaced tin in the 1 solot and 1 at in 1874, with copper 4 at introduced in 1876. The last gold coins were struck in 1895.

Issue 0 – 1835 (trial series)Edit

During the reign of King Rama III (1824–1851), an initiative was made to introduce Thailand’s first flat coinage, intended to replace the widely used cowrie shells. To aid in this modernization of the monetary system, the king employed Robert Hunter, a Scottish merchant, to produce pattern coins.<ref>Elephant-Mueang Thai - Rama III, Thailand. Numista.com. Published 2025. Accessed May 9, 2025. https://en.numista.com/catalogue/pieces174244.html</ref>

The proposed designs featured an elephant motif, which bore resemblance to the coinage of Lanka (modern-day Sri Lanka). Concerned about the symbolic inappropriateness of the elephant, which could imply foreign influence or association, King Rama III ultimately rejected all of the submitted patterns. As a result, none of the proposed coins were officially adopted or denominated.

These pattern coins, though never circulated, represent an early attempt at modernization of Siamese currency prior to the eventual adoption of machine-struck coinage in the reign of King Rama IV.

The first issue of coins were commissioned by Rama IV, though it was never brought into circulation. This was one of the first attempt to replace the bullet coins, but few were ever minted without making it into circulation.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Issue 2, 3 – 1860, 1869Edit

The first circulating issue of the Siamese coins. This marked the start of the move away from using photduang currency. Though in this era, the photduang were still legal tender. In this series, the lower denominations were made of silver, and the higher ones were made of gold. These higher denominations were given nicknames: pot dueng, pit, and tot. Pot dueng means thirty two, as in 1/32 of a chang. The other nickname was the chinkang or one Chinese tamlueng.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The pit means twenty, as in 1/20 of a chang, the other name is ekkang, or one thai tamlueng.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The tot means ten, as in 1/10 of a chang. The coin was also called thukkang, which means two tamlueng.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> In the lower denominations materials such as tin, copper and brass are used, since these are quite low value.

In 1857, a series of trial coins were produced. But due to the broken and rusted die pieces along with the rusted minting press, the coins of this trial series were not to the satisfaction of Rama IV, hence testing continued. The flawed coins of this series is noted to have an inconsistent and rough "sand-like" texture. In 1857-1860 small amounts of trial circulation coins were produced to circulate within the palace walls, so that the noblemen could give feedback and test the new system.<ref name=":1" />

According to the Thai Treasury, regarding the gold coins, they were minted during a period when large amounts of gold were entering Thailand. Inspired by the widespread use of gold coins in other countries, such as the gold coins of England, King Mongkut (Rama IV) ordered the production of gold coins for domestic use. These coins, with their higher value, facilitated trade as the silver coins in circulation at the time were of lower value. They were officially issued on October 29, 1863, and were withdrawn from use in 1908.<ref>เหรียญทองคำทศ พิศ พัดดึงส์ | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024. Accessed December 20, 2024. https://www.treasury.go.th/th/coin-king4-gold/‌</ref>

This series of coins was produced using manually operated machinery that had been presented as a royal gift by Queen Victoria of England. Due to the limited production capacity of these machines, the coins could not be minted in sufficient quantities to meet the country's demand. Consequently, their use was discontinued. This coincided with the arrival of steam-powered machinery, which allowed for more efficient and larger-scale coin production.<ref>เหรียญเงินตราพระมหามงกุฏ-พระแสงจักร (บรรณาการ) | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024. Accessed December 20, 2024. https://www.treasury.go.th/th/coin-king4-tribute/‌</ref> It is worth noting that coins of the half-fuang denomination were not mentioned in official announcements.<ref>เหรียญเงินตราพระมหามงกุฎ - พระแสงจักร | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024. Accessed December 20, 2024. https://www.treasury.go.th/th/coin-k4-1/‌</ref>

In 1863, the royal treasury was reportedly overflowing with gold, with this Rama IV ordered the production of gold coin in additional to the already existing silver series. Intended for circulation, the coin was released to an unfimilar populus, this the people made this coin into jewery instead. A fully intact coin with no holes are exceding rare today.<ref name=":1" />

In 1866, These thin copper coins, in sik (half-fuang) and siao (quarter-fuang) denominations, were produced to replace their thicker counterparts, which were heavier and had the same value. The decision to issue lighter, thinner coins was made after an incident where King Mongkut (Rama IV) distributed the thicker coins during a charitable event, and recipients were injured with head wounds and bruises. His Majesty considered that the copper coins already bore stamped marks and inscriptions (indicating that 2 coins equaled 1 fuang and 4 coins equaled 1 fuang), making them trustworthy. Therefore, thinner and lighter coins would still serve their purpose effectively without causing harm.<ref>เหรียญทองแดงตราพระมหามงกุฎ - พระแสงจักร แบบบาง | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024. Accessed December 20, 2024. https://www.treasury.go.th/th/coin-k4-6/‌</ref>

With the crowning of King Rama 5 in 1868, his majesty decided to tackle the massive counfeiting of base-metal coins in his era. His majesty decided to produce a new large solot (1/128 baht) coin so that the old smaller solot coin were rendered unusable and unprofitable to counterfeit. The large solot coins were only produced for a small period of time, but the coin fufilled its duties and eliminated a huge portion of counterfeited productions.<ref name=":1" />

Issue 4 – 1875Edit

The first series to depict king Rama V, the coins of this issue were made of copper, silver, and gold. Though gold was strangely only used for the 1 fueang denomination.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The new shield emblem was introduced in this issue. This shield was separated into three section. Drawing from western influences, symbols within these sections represented territories Siam was controlling. The tree-headed elephant represented Siamese territory, the bottom-left elephant represented Lan Xang, and the warangka represented Siamese Malaya.

Due to a malfunction in the minting machinery at the government mint, which prevented the production of circulating coinage, King Chulalongkorn ordered the design of this coin series and commissioned its production by a mint in Birmingham, England. This marked the first time that coins were minted abroad for circulation in Siam.<ref>เหรียญทองแดงตรา จ.ป.ร. - ช่อชัยพฤกษ์ | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024. Accessed December 20, 2024. https://www.treasury.go.th/th/coin-k5-2/

‌</ref> The copper coins in this issue were made in the same size as the coins of the United Kingdom, with the Solot being the same size as the Farthing, the Att being the same size as the Half-Penny, and the Siao being the same size as the Penny. The silver coins differ in size to the British counterpart due to the baht being pegged to a different unit of silver. The copper coin in this case were base metal and were not pegged to any standard metal, hence their size tend to differ more throughout history. These copper coins only represent a certain amount of silver.

These silver coins were minted when the Sathit Kuang machinery was put into use in 1889 at the Sathit Kuang Coin Mint, marking the beginning of a new coinage system. The year markings started to appear on the coins from R.S. 120 (1898) onwards.<ref>เหรียญเงิน พระบรมรูป - ตราแผ่นดิน | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024.

Issue 5 – 1888Edit

This was a minor issue, in which the lesser denominations' designs were updated to incorporate the three-partedTemplate:Clarify shield into the design. This copper coin was produced to replace previous versions and was minted in England, with additional production by the Royal Mint of Thailand.<ref>เหรียญทองแดง พระบรมรูป - ตราพระสยามเทวาธิราช | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department.

Decimal coinageEdit

The decimalization of the Thai baht came about at the end of the 19th century. The minister of treasury, Jayanta Mongkol, the Prince Mahisara Rajaharudaya, suggested to King Rama V, that decimalization would make counting easier and further modernize Siam. Initially, there would be one superunit, chang, and one subunit, at. with the baht being in the middle. In summary, 64 at = 1 baht = 1/80 chang. In reality, this was just a simplification of the old system, which was scrapped.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> In which, during the period of 1902–1908, Siam went back to the old system. Though in comparison, at is used as the subunit in Laos, compared to the satang in the Thai baht. The second attempt came at the end of Rama V's reign, where it was more widely accepted and put into effective use.

In 1897, the first coins denominated in satang were introduced, cupronickel Template:Frac, 5, 10, and 20 satang. However, 1 solot, 1, and 2 at coins were struck until 1905 and 1 fueang coins were struck until 1910. In 1908, holed 1, 5, and 10 satang coins were introduced, with the 1 satang in bronze and the 5 and 10 satang in nickel. The 1 and 2 salueng were replaced by 25 and 50 satang coins in 1915. In 1937, holed, bronze Template:Frac satang were issued.

In 1941, a series of silver coins was introduced in denominations of 5, 10, and 20 satang, due to a shortage of nickel caused by World War II. The next year, tin coins were introduced for 1, 5, and 10 satang, followed by 20 satang in 1945 and 25 and 50 satang in 1946. In 1950, aluminium bronze 5, 10, 25, and 50 satang were introduced whilst, in 1957, bronze 5 and 10 satang were issued, along with 1-baht coins struck in an unusual alloy of copper, nickel, silver and zinc. Several Thai coins were issued for many years without changing the date. These include the tin 1942 1 satang and the 1950 5 and 10 satang, struck until 1973, the tin 1946 25 satang struck until 1964, the tin 50 satang struck until 1957, and the aluminium bronze 1957 5, 10, 25, and 50 satang struck until the 1970s. Cupronickel 1-baht coins were introduced in 1962 and struck without date change until 1982.

In 1972, cupronickel 5-baht coins were introduced, switching to cupronickel-clad copper in 1977. Between 1986 and 1988, a new coinage was introduced, consisting of aluminium 1, 5 and 10 satang, aluminium bronze 25 and 50 satang, cupronickel 1 baht, cupronickel-clad copper 5 baht and bimetallic 10 baht. Cupronickel-clad steel 2 baht were introduced in 2005.

Issue 6 – 1897 (transitional)Edit

The old monetary system of Siam was based on a binary system that proved challenging for accounting purposes. This system initially consisted of three main units of currency: Chang, Baht, and Att. Under this system, there were 64 Att to 1 Baht and 80

File:Administrative Division of Siamese Kingdom in 1900.jpg
Siam at the time of coin issue 6 (1897)

Baht to 1 Chang. Despite its widespread use, the system’s complexity made it difficult to manage and calculate.

Recognizing the inefficiencies, the Minister of Treasury proposed to King Rama V that Siam’s currency system should be decimalized. The proposal aimed to modernize the monetary system and align it with the decimal systems increasingly adopted by other countries at the time. King Rama V approved the transition to a decimal-based currency, which simplified accounting processes.

The transition to a decimal currency system faced numerous challenges even before the new coins were issued. Notably, the word "Anachak" (อาณาจักร) was initially misspelled as "อานาจักร," causing controversy. King Rama V intervened, insisting that the most accurate phrasing should be "Siam Ratcha-Anachak" (สยามราชอาณาจักร; Kingdom of Siam).

Despite the initial enthusiasm for the decimal system, the new coins struggled to gain popularity among the public. Many people were unfamiliar with the decimal system and preferred the traditional currency. Consequently, the new coins quickly faded from circulation, forcing the government to continue producing coins under the old system.

The production of coins from the old system persisted until RS 127 / BE 2451 / AD 1907. Ultimately, both pre-decimal coins and the early decimal coins were demonetized on May 17, RS 128 / BE 2452 / AD 1909. Citizens were given a grace period to exchange the demonetized coins for the new decimal currency, with the deadline set for May 16, RS 128 / BE 2452 / AD 1910.

This gradual shift is shown in the fact that coins after the transition often switched between three calendar systems, the CS (Chulasakarat) system, the RS (Rattanakosin Sok) system, the BE (Buddhist Era / Phutthasakarat) system.<ref>2½ Satang - Rama V, Thailand.

Issue 7, 8, 9 – 1908, 1913, 1929, 1939Edit

File:Administrative Division of Siamese Kingdom in 1900.jpg
Siam at the time of coin issue 7 (1900)

In 1908, the Siamese government comission Monnaie de Paris mint to produce a new series of coins for Rama V. The coins were engraved by A. Patey and became the most popular coins to collect amongst the collector today, though with massive conterfeit problems. The coins' shipment were delayed and were shipped to Siam around the time of the passing of Rama V, and so the coins were never put in to circulation. With this, the mint saw fit that the designs were to be adapted to depict Rama VI.<ref name=":1" />

These coins were all produced abroad, and they feature changes in year formatting and design differences over time. The coins were initially produced with the R.S. year system but transitioned to using the B.E. system from 1913 onwards.<ref>เหรียญนิกเกิล ทองแดง ตราอุณาโลม - พระแสงจักร | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024. Accessed December 20, 2024. https://www.treasury.go.th/th/coin-k6-1/

‌</ref> The 1 Baht coins were replaced with banknotes starting in 1918 due to the high cost of silver. The 2 Salung and 1 Salung coins experienced changes in metal composition due to fluctuating silver prices during World War I, and these coins have slight design variations based on these changes.

During issue, there were also various debasements of the silver content of these coins. Initially, the composition was 80% silver and 20% copper. In 1918, during World War I, silver prices surged, leading to a change in the composition to 65% silver and 35% copper. In 1919, the silver percentage dropped further to 50% silver and 50% copper. After the war, in 1919, the composition returned to 65% silver and 35% copper.<ref>เหรียญเงิน พระบรมรูป - ตราไอราพต | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024. Accessed December 20, 2024. https://www.treasury.go.th/th/coin-k6-2/

‌</ref> In 1917, the price of silver rose and exceeded the face value of silver coins. The coins were then melted down and sold. The government solved this by changing the pure silver coin to alloy. Vajiravudh eventually forbade exports of Siamese coins. In 1918, the usage of 1-baht coins was nullified and 1-baht banknotes were introduced. Coins were recalled and kept as a national reserve.

Near the end of this issue of coins, the transition into decimal currency was completed. The Rama VII coin was produced in two denominations, 50 Satang and 25 Satang, and marked the transition from the old currency system of "สองสลึง" (two salung) and "หนึ่งสลึง" (one salung) to the new system using Satang as a unit of currency.<ref>เหรียญเงิน พระบรมรูป - ตราช้างทรงเครื่อง | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024. Accessed December 20, 2024. https://www.treasury.go.th/th/coin-k7-1/

This series of coins is distinctive as it lacks the royal insignia and the state seal, which were commonly featured in earlier designs. This series also includes a 20 satang denomination; thus at one point the 25-satang and the 20-satang circulated at the same time.<ref>เหรียญเงิน ทองแดง ตราลายกระหนก | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024. Accessed December 20, 2024. https://www.treasury.go.th/th/coin-k8-3/‌</ref> The half-satang was introduced in 1937 to address the issue of low-value currency units in Thailand. The value of 1 Satang was considered too high for certain low-priced items, causing economic hardship for the poor. Previously, 1 Baht could be exchanged for 128 Solot, but after the switch to Satang, 1 Baht was only equivalent to 100 Satang. The introduction of this coin aimed to make it easier for ordinary people to purchase items without the burden of inflated prices. The coin was produced only once and was discontinued soon afterwards. It was minted in Japan and first issued on July 12, 1937.<ref>เหรียญทองแดง ครึ่งสตางค์ ตราอุณาโลม - พระแสงจักร | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024. Accessed December 20, 2024. https://www.treasury.go.th/th/coin-k8-2/‌</ref>

In 1942, a group of denominations switched material due to the costs of World War II: the 1-satang coin lost its hole in the middle and was made smaller.<ref>เหรียญดีบุก ตราลายกระหนก พ.ศ. 2485 | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department.

Issue 11 – 1946Edit

This was the first series minted in the reign of King Ananda Mahidol (Rama VIII), and it marked the return of national symbols, such as the Garuda emblem, which had been used as the national seal since the Ayutthaya period. This emblem, created during

the reign of King Chulalongkorn (Rama V), became the national seal to be used permanently, avoiding the need for a new one with each reign. There are two versions of this series minted in the same year, the young portrait and the teen portrait.<ref>เหรียญดีบุก พระบรมรูป - ตราพระครุฑพ่าห์ (ทรงเจริญพระชนมพรรษา) | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024. Accessed December 20, 2024. https://www.treasury.go.th/th/coin-k8-6/

‌</ref>

After World War 2, the government instructed the mint to start the production of coins depicting Rama VIII, since prior to this coins with no royal portrait were minted. These coins were made with pure tin. These coins were made with particularly low quality tin. During circulation, a lot of the coins from this series were damaged, lost, or rendered unusable. Even so, after the death of Rama VIII, the mint continue to produce this series of coins until the burial of Rama VIII, a tradition seen in the latest series of coins where new series were not introduced until after the coronation. Thus, this series of coins were used for 4 years after the passing of King Ananda Mahidol (Rama VIII).<ref name=":1" />

While this series lacks a circulating 1 baht coin, a trial piece were produced but never released into circulation.<ref name=":1" />, the coin was 30.5 mm in diameter and made with tin. As a reference, this is the size of 5 baht coin up until issue 16 coins, or the last Rama 9 series of coins.

Current coinageEdit

The current coin series is the 14th issue.

In 2008, in the 13th issue, the Ministry of Finance and the Royal Thai Mint announced the 2009 coin series, which included changes in materials to reduce production costs as well as an update of the image on the obverse to a more recent portrait of the king. The two-baht coin, confusingly similar in color and size to the one-baht coin, was changed from nickel-clad low-carbon steel to aluminium bronze. New two-baht coin was the first of the new series released on 3 February 2009, followed by the satang coins in April, a five-baht coin in May, a ten-baht coin in June, and a one-baht coin in July 2009.

In 2018, the Royal Thai Mint and the Ministry of Finance issued a new series of general circulation coins, featuring the same standard specifications, but feature a portrait of its current king, Vajiralongkorn.

RemarksEdit

  1. The 1, 5 and 10 satang are used only internally between banks and are not in circulation.<ref>{{#invoke:citation/CS1|citation

|CitationClass=web }}</ref>

  1. Older coins, some of which are still in circulation, had only Thai numerals, but newer designs also have Arabic numerals.
  2. The standard-issue 10-baht coin has, at the 12 o'clock position on the reverse, raised dots corresponding to Braille cell dot 1 and dots 2-4-5, which correspond to the number 10.
  3. 10-baht coins are very similar to 2-euro coins in size, shape and weight, and are likewise bi-metallic, although they are worth only about €0.25.

Calendar systems of Thai coinageEdit

Over the course of Siamese coinage history, various calendar systems were used. The first one to be applied onto the coins was the burmese calendar system or Chula Sakarat (C.S.), which was subsequently supplanted by the Rattanakosin Sok system (R.S.) which started at the founding of the Rattanakosin Kingdom. The system in use right now is the Phuttha Sakarat system or the Buddhist calendar (B.E.)

Money and unit of massEdit

Ngoen (เงิน) is Thai for "silver" as well as the general term for money, reflecting the fact that the baht (or tical) is foremost a unit of weight for precious metals and gemstones. One baht = 15.244 grams.<ref>"A sure bet or fool's gold?", Bangkok Post 2010-01-10Template:Dead link</ref> Since the standard purity of Thai gold is 96.5 percent, the actual gold content of one baht by weight is 15.244 × 0.965 = 14.71046 grams; equivalent to about 0.473 troy ounces. 15.244 grams is used for bullion; in the case of jewellery, one baht should be more than 15.16 grams.

The Bank of Thailand adopted a series of exchange controls on 19 December 2006, which resulted in a significant divergence between offshore and onshore exchange rates, with spreads of up to 10 percent between the two markets. Controls were broadly lifted on 3 March 2008 and there is now no significant difference between offshore and onshore exchange rates.<ref>Template:Cite news</ref>
