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.
Postage stamps and postal history of Switzerland
Swiss stamps are inscribed with the word "Helvetica", rather than "Schweiz", "Suisse" "Svizzera", or "Svizra". With four official languages-German, French, Italian, and Romansch. The Swiss would have had to put all four languages on each stamp, quite a problem to overcome with such limited space on a stamp.
