The franc (sign: Fr. or SFr.; German: Franken, French and Romansh: franc, Italian: franco; code: CHF) is the currency and legal tender of Switzerland and Liechtenstein; it is also legal tender in the Italian exclave Campione d'Italia. The Swiss National Bank (SNB) issues banknotes and the federal mint Swissmint issues coins.
Although 22 cantons and half-cantons issued coins between 1803 and 1850, less than 15% of the money in circulation in Switzerland in 1850 was locally produced, with the rest being foreign, mainly brought back by mercenaries. In addition, some private banks also started issuing the first banknotes, so that in total, at least 8000 different coins and notes were in circulation at that time, making the monetary system extremely complicated.
In order to solve this problem, the new Swiss Federal Constitution of 1848 specified that the federal government would be the only entity allowed to make money in Switzerland. This was followed two years later by the first Federal Coinage Act, passed by the Federal Assembly on 7 May 1850, which introduced the franc as the monetary unit of Switzerland. The franc was introduced at par with the French franc. It replaced the different currencies of the Swiss cantons, some of which had been using a franc (divided into 10 batzen and 100 centimes) which was worth 1 1⁄2 French francs.
The smaller denomination, a hundredth of a franc, is a Rappen (Rp.) in German, centime (c.) in French, centesimo (ct.) in Italian, and rap (rp.) in Romansh. The ISO code of the currency used by banks and financial institutions is CHF, although Fr. is also widely used by businesses and advertisers; some use SFr. for Swiss Franc; the Latinate "CH" stands for Confoederatio Helvetica.
Given the different languages used in Switzerland, Latin is used for language-neutral inscriptions on the coins.
