1 Thaler - Peter Ernest, Bruno, Gebhard and John George

Mansfeld-Friedeburg operated under a peculiar inheritance structure that forced multiple heirs to share both territory and minting rights simultaneously, producing joint-issue thalers that bear the names of all ruling counts together. This piece names four co-rulers — Peter Ernest, Bruno, Gebhard, and John George — a consolidation reflecting the county's habitual partition and reunification across generations of the Mansfeld dynasty, a family whose copper-mining wealth funded an outsized political presence in the Holy Roman Empire well into the late sixteenth century.

The two-year emission window of 1587–1588 was narrow even by joint-reign standards.
