These are banknotes and coins that a relative left behind from a trip about 30 years ago. They were issued shortly after the separation of the Czech Republic and Slovakia. The front of the 20 Koruna banknote (1994) features Přemysl Otakar I, a Bohemian king from the 13th century. The back depicts some kind of coat of arms. The 20 Koruna banknote is no longer in circulation, so it's not easily obtainable. There are three types of coins: 1 Koruna, 2 Koruna, and 10 Koruna. Type... Foreign currency/coins
