1 Thaler - Clemens Wenzel of Sachsen Konventionstaler

Clemens Wenceslaus of Saxony — the last Elector-Archbishop of Trier — was an unlikely ecclesiastical ruler: a Wettin prince appointed to the see in 1768 largely through dynastic maneuvering, who spent his tenure more preoccupied with Enlightenment court culture than with diocesan affairs. His Trier coinage was struck under the Konventionstaler standard established by the Austro-Bavarian convention of 1753, which fixed the thaler at 1/10 of the Cologne mark — a monetary agreement that brought decades of relative stability to the fragmented coinage of the Holy Roman Empire's ecclesiastical states.
