WIR Bank
The WIR Bank, formerly the Swiss Economic Circle (German: "Wirtschaftsring-Genossenschaft"), or WIR, is an independent complementary currency system in Switzerland that serves businesses in hospitality, construction, manufacturing, retail and professional services. WIR issues and manages a private currency, called the WIR Franc, which is used in combination with the Swiss Franc to generate dual-currency transactions.
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.
