1/4 Thaler - John George I and August Vicariat

Issued during the Imperial Vicariate of 1612, this piece commemorates the joint administration of Saxony exercised by John George I and his brother August following the death of Emperor Rudolf II and the interregnum before Matthias was formally crowned. The Wettin electors held traditional Vicariate authority over the German territories governed by Saxon law — a privilege dating to the Golden Bull of 1356 — and routinely struck coinage to advertise that constitutional role.

The Vicariate issues of 1612 are among the more precisely datable Saxon coins of the period, tied directly to the weeks-long gap in imperial authority.
