The 1 koruna coin was minted in the German protectorate of Bohemia and Moravia between 1941 and 1944 during World War II. The provinces of Bohemia and Moravia are currently part of the Czech Republic. Germany occupied the Sudetenland of Czechoslovakia in 1938 under the terms of the Munich Agreement and in March 1939 invaded the remainder of Czechoslovakia and established the protectorate. Made entirely of zinc, the 1 koruna is an emergency issue type, similar to the coins of other German occupied territories. Following the war, the provinces of Bohemia and Moravia were reincorporated into Czechoslovakia.
