Swiss franc
The Swiss franc is the currency and legal tender of Switzerland and Liechtenstein and also legal tender in the Italian exclave of Campione d'Italia. Although not formally legal tender in the German exclave of Büsingen am Hochrhein (the sole legal currency is the euro), it is in wide daily use there; with many prices quoted in Swiss francs. The Swiss franc is the only version of the franc still issued in Europe.
International status and usage of the euro
There were political concerns that Serbia could use the currency to destabilise these territories (Montenegro was then in a union with Serbia) so they received Western help in adopting and using the mark (though there was no restriction on the use of the dinar or any other currency). They switched to the euro when the mark was replaced. In North Kosovo, which is mainly populated by the Serbian minority, the Serbian dinar, which replaced the Yugoslav dinar, continues to be used despite its lack of recognition or use elsewhere in Kosovo.
