1 Thaler - Joachim Frederick of Brandenburg

Joachim Frederick held the Archbishopric of Magdeburg as a Protestant administrator — never ordained, never consecrated — a direct consequence of the Peace of Augsburg's provision allowing Lutheran princes to control ecclesiastical territories without taking holy orders. He was seventeen when this thaler was struck, governing a nominally Catholic see on behalf of his father, Elector John George of Brandenburg. The arrangement was constitutionally awkward and theologically absurd, which is precisely why it produced coins at all: establishing administrative presence required a visible, circulating currency bearing his authority.
