Slovakia has been a member of the European Union since May 2004, and is a member of the European Economic and Monetary Union. Slovakia adopted the euro on 1 January 2009, replacing its previous currency, the Slovak koruna.
Slovak koruna
In 1939, Czechoslovak notes for 100, 500 and 1000 korún were issued with SLOVENSKÝ ŠTÁT overprinted on them for use in Slovakia. That year also saw the introduction of 10 and 20 koruna notes by the government.
