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.
Zürich thaler
The Thaler was the currency of Zürich until 1798. It was subdivided into 2 "Gulden", each of 36 "Schillinge", with the Schilling divided into 4 "Rappen" or 12 "Haller". It was replaced by the Frank of the Helvetian Republic in 1798. This was, in turn, replaced by the Zürich Frank. The thaler was worth of a Cologne mark.
