Slovakia
The Slovak Republic and the Czech Republic went their separate ways after 1 January 1993, an event sometimes called the Velvet Divorce. Slovakia has remained a close partner with the Czech Republic. Both countries co-operate with Hungary and Poland in the Visegrád Group. Slovakia became a member of NATO on 29 March 2004 and of the European Union on 1 May 2004. On 1 January 2009, Slovakia adopted the Euro as its national currency.
Slovak koruna
Compared to the pre-war Czechoslovak koruna, the Slovak koruna coins had an additional 50 Ks, the silver content of the 10 and 20 Ks coins was reduced from 700 ‰ to 500 ‰ and all but 5 Ks shrank in physical sizes. The designers were Anton Hám, Andrej Peter, Gejza Angyal, Ladislav Majerský and František Štefunko. Coins were minted in the Kremnica mint.
