The Duplone currency was used in various Swiss cantons in the late 1700s and early 1800s. Generally, one Duplone was equal to 16 Franken. Duplones had a consistent gold fineness of 0.900 across Switzerland.
The coin depicts crowned coat-of-arms and ‘RESPUBLICA SOLODORENSIS’ legends. And the other side of the coin features Saint Ursus standing, facing front and holding a flag with inscribed legends, ‘S URSUS MART 1789’.
Until 1798, Thaler was the currency of the Swiss canton of Solothurn which was further sub-divided into 40 Batzen, each of 4 Kreuzer or 8 Vierer. In 1798, the currency was replaced by the Frank of the Helvetian Republic.
In the late 18th century, billon coins were issued in denominations of 1 Vierer, 1, 2 and 4 Kreuzer along with silver 10 and 20 Kreuzer, 10 and 20 Batzen, and gold 1?4, 1?2, 1 and 2 Duplone.
