Franc
The Swiss franc (ISO code: CHF or 756), which appreciated significantly against the new European currency from April to September 2000, remains one of the world's strongest currencies, worth today around five-sixths of a euro. The Swiss franc is used in Switzerland and in Liechtenstein. Liechtenstein retains the ability to mint its own currency, the Liechtenstein franc, which it does from time to time for commemorative or emergency purposes.
Banknotes of the Swiss franc
During the 19th century the cantons (states) of Switzerland had the right to print their own notes. Following the law of 8 March 1881 the Swiss National Bank had the exclusive right to issue banknotes in Switzerland. Its first notes were issued in 1907. Since then, nine series of Swiss franc notes have been printed, six of which have been completely released for use by the general public, and a new series started being released in 2016.
