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.
Geography of Switzerland
Switzerland is also divided by language. There are four official languages: German (spoken by 63.7% of population), French (by 20.4% of population), Italian (by 6.5%) and Romansh (0.5%). From Bern east (except Ticino) the population generally speaks German. West of Bern, the population generally speaks French. In the southern Canton of Ticino, most people speak Italian. Romansh, a group of dialects descended from Vulgar Latin, is spoken in several regions in the canton of Graubünden.
