1⁄12 Thaler - Ludwig Constantin von Rohan-Guéménée

Ludwig Constantin von Rohan-Guéménée was appointed Prince-Bishop of Strasbourg in 1756 through the same dynastic maneuvering that kept the Rohan family in control of that see for the better part of the eighteenth century — a grip they held until the Revolution dismantled it entirely. The bishopric functioned as a quasi-sovereign principality within the Holy Roman Empire, giving the bishop full coining rights despite the territory's ambiguous political position between French royal authority and imperial jurisdiction.

1759 places this issue squarely in the Seven Years' War, when silver circulation across the Rhine territories was under considerable strain from military requisitioning on both sides.
