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.
Euro gold and silver commemorative coins (Slovakia)
These special coins have a legal tender only in Slovakia, unlike the normal issues of the Slovak euro coins, which have a legal tender in every country of the Eurozone. This means that the commemorative coins made of gold and silver cannot be used as money in other countries. Furthermore, as their bullion value generally vastly exceeds their face value, these coins are not intended to be used as means of payment at all—although it remains possible. For this reason, they are usually named Collectors' coins.
