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.
Fribourg gulden
The "Gulden" was the currency of the Swiss canton of Fribourg until 1798. It was subdivided into 14 "Batzen", each of 4 "Kreuzer" or 16 "Denier". It was replaced by the Frank of the Helvetian Republic in 1798. This was, in turn, replaced by the Fribourg Frank.
