Adam Frederick of Seinsheim held both the Bishopric of Würzburg and the Bishopric of Bamberg simultaneously from 1757, an unusual dual tenure that made him one of the more administratively powerful ecclesiastical princes in the Holy Roman Empire during the Seven Years' War. This coin was struck in 1761 — the war's penultimate year — when Franconia had seen Prussian and Imperial troop movements disrupt trade and drain treasury reserves across the region. The Konventionstaler standard itself had been formalized by the Munich Convention of 1753, binding Bavaria and Austria to a common silver weight that Würzburg adopted to facilitate cross-border commerce.
