⅔ Thaler - Charles Frederick William

Brandenburg-Ansbach was by 1753 a margraviate in visible decline, its treasury chronically strained and its ruling line heading toward extinction. Charles Frederick William — Karl Friedrich Wilhelm — held the title but exercised limited independent authority, and coinage from his reign was issued partly to assert a sovereignty that was already slipping. The ⅔ Thaler denomination itself was a peculiarly North German convention, pegged to the 1690 Leipzig foot and designed to circulate across Protestant territories where the full Thaler was often hoarded.

The margraviate was absorbed into Prussia in 1791 when the last margrave, Alexander, died without heirs.
