Czechoslovak koruna
The Czechoslovak koruna (in Czech and Slovak: "Koruna československá", at times "Koruna česko-slovenská"; "koruna" means "crown") was the currency of Czechoslovakia from April 10, 1919, to March 14, 1939, and from November 1, 1945, to February 7, 1993. For a brief time in 1939 and again in 1993, it was also the currency in separate Czech and Slovak republics.
