1 Conventionsthaler - Christoph Francis

Christoph Franz von Buseck was the last Prince-Bishop of Bamberg. He issued this thaler just six years before Napoleon's Confederation of the Rhine dissolved the ecclesiastical principality entirely in 1806, ending over eight centuries of church rule in the region. The Bishopric was absorbed into the newly created Kingdom of Bavaria without ceremony.

The Convention standard itself — established by the 1753 treaty between Austria and Bavaria — was already under strain by 1800, with French-influenced monetary chaos eroding cross-border silver agreements across the German states.
