The Thaler was the currency of St. Gallen until 1798. It was subdivided into 2 Gulden, each of 60 Kreuzer or 240 Pfennig. It was replaced by the Frank of the Helvetian Republic in 1798. This was, in turn, replaced by the St. Gallen Frank. Coins were issued by both the Abbey of St. Gall and the City.
Coins
In the late 18th century, the Abbey coinage consisted of billon 1 Pfennig, 1, 2, 4, 5 and 6 Kreuzer, together with silver 10, 12, 15, 20 and 30 Kreuzer, 1 Gulden, 1⁄2 and 1 Thaler. The city coinage consisted of billon 2, 3, 6 and 15 Kreuzer coins.
