Duplone
The duplone was a currency used in various Swiss cantons in the late 1700s and early 1800s.[1][2] Although there is a wide range of conversions due to the differing sizes and gold contents of different canton's duplones, 1 duplone is generally equal to 16 franken.[3] This conversion is exact in both the cantons of Graubünden and Berne.[4][5] Duplones had a consistent gold fineness of 0.900 (just below 22 karats)[6] across Switzerland.[2]
