Editing Overprint (section)

== Overprints on currency ==
The design and printing of valid paper [[currency]] is rarely done hastily and overprints are extremely rare, but in times of crisis such measures have been taken. After World War I, the various successor states of the [[Austro-Hungarian Empire]] made multilingual overprints to their old Imperial currency until new notes could be designed and circulated.

Currency overprints were also used during World War II to mark all [[United States dollar]]s in the Hawaiian islands. These [[Hawaii overprint note]]s were made in case the islands were captured and the invading forces gained control of the money.<ref>{{Cite web|url=http://www.infoplease.com/askeds/bills-stamped-hawaii.html |title=Bills Stamped with Hawaii |publisher=Infoplease |date=1944-10-21 |access-date=3 September 2011 }}</ref>

Another unusual overprinting situation involving U.S. notes occurred when limited numbers of series 1935A [[silver certificate]] [[United States one-dollar bill|dollar bill]]s were overprinted with either a red "R" or an "S".  This indicated they were made of "regular" or "synthetic" paper and was a test of their wearing qualities.<ref>[http://www.uspapermoney.info/serials/all___s.html Special issue $1 notes]</ref>

The [[Haiti]]an [[Gourde]] was overprinted after the unexpectedly rapid fall of the [[Jean-Claude Duvalier|Baby Doc Duvalier]] regime.<ref>{{Cite web |url=http://www.travelinghaiti.com/haitian-currency.asp |title=Haitian Currency |year=2011 |publisher=Traveling Haiti.com |access-date=3 September 2011 }}</ref> The overprint consisted of a red circle with a slash across it with the date of the end of the Duvalier regime (7&nbsp;February 1986) printed below in red. The brusque symbol obscured the images of Baby Doc and [[François Duvalier|Papa Doc]] until they were replaced with images of figures from Haitian history. Something similar was done in [[Iran]] in 1979 when [[Mohammad Reza Pahlavi|the Shah]]'s picture was covered by an intricate design.
