Editing Banknote (section)

===Other materials===
Over the years, a number of materials other than paper have been used to print banknotes. This includes various textiles, including silk, and materials such as leather.<ref>S.K. Singh, ''Bank Regulation'', Discovery Publishing House, New Delhi, 2009, pp. 26–27.</ref>

Silk and other fibers have been commonly used in the manufacture of various banknote papers, intended to provide both additional durability and security. [[Crane and Company]] patented banknote paper with embedded silk threads in 1844 and has supplied paper to the [[United States Treasury]] since 1879. Banknotes printed on pure silk "paper" include "emergency money" [[Notgeld]] issues from a number of German towns in 1923 during a period of fiscal crisis and [[hyperinflation]]. Most notoriously, [[Bielefeld]] produced a number of silk, leather, velvet, linen and wood issues. These issues were produced primarily for collectors, rather than for circulation. They are in demand by collectors. Banknotes printed on cloth include a number of Communist Revolutionary issues in China from areas such as [[Xinjiang]], or Sinkiang, in the United Islamic Republic of East [[Turkestan]] in 1933. Emergency money was also printed in 1902 on [[khaki]] shirt fabric during the [[Second Boer War|Boer War]].

[[Cotton]] fibers, together with 25% linen, are the material of the banknotes in the United States. Leather banknotes (or coins) were issued in a number of [[siege]]s, as well as in other times of emergency. During the [[Russian America|Russian administration of Alaska]], banknotes were printed on [[Alaskan parchment scrip|sealskin]]. A number of 19th-century issues are known in Germanic and Estonia, including the places of [[Tartu|Dorpat]], [[Pärnu|Pernau]], [[Tallinn|Reval]], [[Võru|Werro]], and [[Võisiku|Woiseck]]. In addition to the Bielefeld issues, other German leather [[Notgeld]] from 1923 is known from [[Borna, Leipzig|Borna]], Osterwieck, Paderborn and Pößneck.

Other issues from 1923 were printed on wood, which was also used in Canada in 1763–1764 during [[Pontiac's Rebellion]], and by the [[Hudson's Bay Company]]. In 1848, in [[Bohemia]], wooden checkerboard pieces were used as money.

Even [[card money|playing cards]] were used for currency in France in the early 19th century, and in French Canada from 1685 until 1757, the Colony of Louisiana, Dutch Guiana, and in the [[Isle of Man]] in the beginning of the 19th century, and again in Germany after World War I.

Most recently, [[Bisphenol S]] (BPS), has been frequently used in the production of banknotes worldwide. BPS is an [[endocrine disruptor]] that is subject to human dermal absorption through handling banknotes.<ref>{{cite journal |title=Bisphenol S, a New Bisphenol Analogue, in Paper Products and Currency Bills and Its Association with Bisphenol A Residues |author=Liao C |author2=Liu F |author3= Kannan K |pmid=22591511 |doi=10.1021/es300876n |volume=46 |issue=12 |date=2012 |journal=Environmental Science & Technology |pages=6515–6522|bibcode=2012EnST...46.6515L }}</ref>
