1 Groschen - John George III

Mansfeld-Eisleben was a copper-mining county in the Harz foothills, but by the 1660s the mines were exhausted and the county was drowning in debt. John George III ruled a rump territory — the result of decades of partition among Mansfeld heirs — and his small silver issues of this period reflect a jurisdiction minting almost out of habit rather than economic necessity. The county was absorbed into electoral Saxony just years after these groschen were struck.
