The Swiss franc is also the currency used for administrative and accounting purposes by most of the numerous international organisations that are headquartered in Switzerland.
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.
