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.
Challenge coin
The challenge coin tradition was introduced into the Swiss Armed Forces by American officers on training missions and other assignments for the Organization for Security and Co-operation in Europe, of which Switzerland is a member. Coins are not issued, but rather ordered and paid for by Swiss officers of various branches within the Army.
