6 Mariengroschen - Charles William Ferdinand

Charles William Ferdinand — who would later command Prussian forces at Valmy in 1792 and issue the notorious Brunswick Manifesto threatening Paris with destruction — was still a relatively cautious reformer during the years this coin circulated. The Mariengroschen denomination itself was a north German peculiarity, its name derived from a medieval Marian devotional tradition that had long outlasted its religious meaning by the time these were struck at the Zellerfeld or Clausthal mint in the Harz.

The four-year span of this type likely reflects a routine recoinage rather than any monetary disruption.
