This is money used by prisoners-of-war at Theresienstadt prison. The notes are for 10, 5, 2, and 1 kronen, as well as a 20 heller note. Some prisons issued their own currency and, though officers who were prisoners did not have to work for their captors, other, enlisted men had to if asked to do so. Prisoners who worked were not paid using official Austrian currency, but rather by prison money, which could only be spent at the prison store. Some other prisons had their own currency printed for distribution and use within that prison. These Theresienstadt notes have a serial number printed only on one side and have this German text printed on them: 'Dieser Schien gelt nur innerhalb des k. und k. Kriegsgefangenenlagers Theresienstadt wert fur... kroner', which translates approximately as: 'This apparent money is for use only within the Imperial and Royal prisoner-of-war camp Theresienstadt, value... kroner'. Theresienstadt is also the prison where Gavrilo Princip, who shot Archduke Franz Ferdinand in 1914, died in 1918 of tuberculosis, in cell number 1. Unfortunately, Theresienstadt became a Nazi concentration camp during World War Two, and special, prison currency was also printed for those who were held there.
