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.
Kosovo and the euro
Before the establishment of UNMIK, Kosovo (as part of Serbia) was bound to Yugoslav monetary policy, and the Yugoslav dinar. However, war-time inflation and tensions with the Federal Republic of Yugoslavia had severely discredited the Yugoslav dinar. As a result, many preferred to use and hoard foreign currencies instead of relying on the dinar. The most frequently used foreign currency was the German mark, although the U.S. dollar and Swiss franc were also widely used.
