⅔ Thaler - Ulrich VI

The Bishopric of Chur controlled the Alpine passes of the Graubünden, and its coinage during the late seventeenth century reflects the region's peculiar position as a transit zone between competing Habsburg, French, and Venetian commercial interests. The ⅔ Thaler denomination — a fraction that seems odd to modern eyes — was in fact a practical response to northern German monetary conventions, where the ⅔ Thaler had become a widely accepted trading unit after the Leipzig Monetary Convention of 1690 attempted to stabilize circulation across fragmented territories.

Ulrich VI von Mont served as Prince-Bishop of Chur from 1661 until his death in 1692, a tenure long enough to see multiple coinage programs through.
