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.
Swiss franc
After 1815, the restored Swiss Confederacy attempted to simplify the system of currencies once again. 
As of 1820, a total of 8,000 distinct coins were current in Switzerland: those issued by cantons, cities, abbeys, and principalities or lordships, mixed with surviving coins of the Helvetic Republic and the pre-1798 Helvetic Republic. In 1825, the cantons of Berne, Basel, Fribourg, Solothurn, Aargau, and Vaud formed a monetary "concordate", issuing standardised coins, the so-called "Konkordanzbatzen", still carrying the coat of arms of the issuing canton, but interchangeable and identical in value. The reverse side of the coin displayed a Swiss cross with the letter C in the center.
