⅔ Thaler - John Frederick

John Frederick of Brandenburg-Ansbach ruled the margraviate from 1667 until his death in 1686, a period during which the ⅔ Thaler denomination — effectively the Gulden or two-thirds piece — became a dominant trade coin across the fragmented German states following the monetary chaos of the Thirty Years' War. The denomination itself emerged from deliberate monetary policy: the Leipzig Convention of 1690 would later try to rein in its proliferation, but through the 1670s mints across the Empire struck them aggressively to satisfy commercial demand.

Brandenburg-Ansbach operated its mint at Schwabach during this period.
