1 Thaler - Francis Louis of Erthal Konventionstaler

Franz Ludwig von Erthal was simultaneously Prince-Bishop of both Würzburg and Bamberg from 1779 until his death in February 1795, one of the last ecclesiastical rulers to exercise genuine temporal authority over these Franconian territories before Napoleon's reorganization swept them away. His reign coincided with the Revolutionary Wars, and French forces were advancing into the Rhineland precisely as this thaler was being struck. The Bishopric of Würzburg would survive him by only a decade — secularized in 1803 under the Reichsdeputationshauptschluss.

The Konventionstaler standard dated to the 1753 Munich Convention between Austria and Bavaria, fixing the coin at 10 to the Cologne mark of silver.
