This article concerns overprints on stamps and currency. For the use of the term in printing, see Overprinting

An overprint is the addition of text (and sometimes graphics) to the face of a postage stamp (or banknote) after it has been printed (although some overprints are solely in the selvedge area of souvenir sheets). Overprints have been used for many purposes over the years. They have been used as surcharges, commemorations, and control marks.

[edit] Surcharges

German hyperinflation surcharge 1923, 2 million marks over 5 thousand marks

A surcharge is an overprint that alters or confirms the face value of the stamp. These are commonly used when needed types of stamp are unavailable, whether because new shipments are delayed, because circumstances have changed too quickly to get appropriate new stamps, to use up existing stamp stocks, or because stamps had been used up and needed replacing.

One famous example of surcharging came in the German hyperinflation of 1921-1923. ^[1] Stamps in the 10-20 pfennig range were no longer useful for paying postage (hundreds would have been required on a normal letter), so at first the government overprinted existing stamps with values up to 10 marks while it was designing new ones, but by 1923 even its printed stamps ranging up to 75,000 marks became useless and had to be surcharged with higher values, up to 2,000,000 marks and then a round with values up to 10,000,000,000 marks (10 billion) before the financial system was reset.

Many countries have used surcharges when converting to new currencies, for example many Commonwealth countries chose to convert to decimal currency in the late 1960s.

Countries with political instability have frequently had to resort to surcharges because the existing stocks were exhausted and there was no one in charge to order more.^{[citation needed]} In many cases, countries have resorted to overprinting revenue stamps, telegraph stamps, and seemingly anything else they could find that was perforated and gummed - and, in the worst case - stamps that had been previously surcharged.

Occasionally surcharges have been applied by individual postmasters, especially those in the remotest locations and in the early days of stamps, but because of the possibilities for abuse, this is rarely approved by the national government. Overprints applied by an entity other than an official stamp-issuing entity are called "private overprints."

[edit] Occupation overprints

Overprints have been commonly used where a country or part of a country has been occupied and the occupying country has printed its name on existing stocks of stamps.

[edit] Commemorative overprints

Overprints have also been used as commemoratives, as a lower-cost alternative to designing and issuing special stamps. The United States, which historically has issued very few overprints, did this in 1928 for issues commemorating Molly Pitcher and the discovery of Hawaii. A special subcategory is overprinting on sports-related stamps in events such as the Olympic Games. For example, on April 8, 1998 Guyana issued a set of 32 stamps showing team pictures of all the participants in that year's World Cup championships; on August 20, after the tournament, eight of these were reissued with an overprint announcing France as the winner. This practice is frowned upon by many philatelists. An unfortunately common use of commemorative overprints has been due to revolution; the overprint may obscure or even blot out the previous ruler's head, but invariably proclaims the new regime, frequently with the date of its takeover. The Provisional Government of Southern Ireland printed its stamps in this manner during 1922, using standard British issues.

[edit] Control devices

Overprints also have been used as control devices to deter theft. In the 19th century Mexico was plagued by theft of stamps on their way to remote post offices. To address this, stamps were shipped from Mexico City to the local districts where they were overprinted with the district name. They were not valid for postage without the overprint. (Later, invoice numbers were overprinted before shipment from Mexico City as an additional protection against theft.) The United States used a similar strategy to deal with thefts in Kansas and Nebraska in 1929, overprinting the current definitive issue with "Kans." and "Nebr." before they were shipped from Washington, to make it more difficult to sell stolen stamps out of state.

[edit] Specimen overprints

British stamps are encountered with the word SPECIMEN or CANCELLED applied as an overprint. These were usually applied in black, but other colours are known. These overprints were applied either by the printers as colour standards for matching later printings or by the authorities (at Somerset House), as reference copies or on examples which were being sent to other members of the UPU, (Universal Postal Union). In addition to this booklet panes were cancelled by the use of a punched hole applied by a ticket punch. This was applied by folding the stamps and punching across the fold in addition to the word CANCELLED. These were used in booklets sent out to companies which had advertising within the booklets, so that they could see the finished results but were unable to use the stamp.

[edit] Overprints on currency

Haitian Currency Overprint.

Overprints have occasionally been used on currency such as the overprints found on Haitian Gourdes at the end of the Baby Doc Duvalier regime.^{[citation needed]} The overprint consisted of a red circle with a slash across it with the date of the end of the Duvalier regime—February 7, 1986—printed below in red. The overprint was placed over the image of Baby Doc and his father the infamous Papa Doc, François Duvalier that was subsequently replaced with images of figures from the history of the Haitian Republic. Something similar was done in Iran in 1979 when the Shah's picture was covered by an intricate design.

Currency overprints were also used during World War II to mark U.S. currency in use in Hawaii with the word "HAWAII" in case the Hawaiian islands were captured and the Japanese tried to use the money. (See HAWAII Overprint Note.) ^[2]
