1 Thaler - Clemens Wenzel of Sachsen Konventionstaler

Clemens Wenceslaus of Saxony — the last Elector-Archbishop of Trier — was appointed to that see in 1768 at age thirty, owing his position almost entirely to dynastic pressure from his uncle Augustus III of Poland rather than any ecclesiastical distinction. The Konventionstaler standard itself had been formalized by the 1753 Munich Convention between Austria and Bavaria, an attempt to stabilize the chaotic patchwork of silver coinage circulating across the Holy Roman Empire's western territories.

Clemens Wenceslaus would eventually flee Trier ahead of French Revolutionary forces in 1794, ending nearly a millennium of ecclesiastical rule over the electorate. This 1771 piece predates that collapse by over two decades.
