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.
Postage stamps and postal history of Switzerland
All of the preceding issues were declared invalid on 1 October 1854, and replaced with the seated allegorical figure "Helvetia", the first of several issues known as "seated Helvetias". The figure was embossed but only the outline was colored, making it rather hard to pick out. This was the first issue to deal with the multiple languages of Switzerland; in addition to the word "FRANCO" at the top, the other three sides listed the denomination in rappen, centimes, and (Italian) centesimi.
