1 Thaler - Peter Ernest I, John Albert, Bruno II, Hoyer Christoph and John George IV

Mansfeld's copper mines had made the county one of the most productive mineral territories in the Holy Roman Empire, but by the 1580s the counts were drowning in debt despite — or because of — that wealth. This thaler was struck under a joint administration of five co-ruling counts, a governance arrangement born of the Mansfeld partition system that divided comital authority among surviving male heirs rather than consolidating it. The result was chronic fiscal dysfunction and near-constant litigation between branches of the family.

The Friedeburg line in particular was careening toward insolvency by mid-decade, and thalers of this joint issue circulated briefly before the county's financial collapse forced outside creditors to intervene directly in its administration.
