1/2 Thaler - Christian III

Christian III used the Schleswig-Holstein mint at Rendsburg to consolidate his authority over the duchies following the Count's War, which had ended only a decade earlier with his contested seizure of the Danish throne. The 1545 half thaler belongs to a period of deliberate monetary standardization, as Christian worked to align his German duchy coinage with the emerging Reichstaler system while keeping it administratively distinct from his Danish royal issues.

The Rendsburg mint was jointly administered under the duchy's peculiar co-governance structure — Holstein being an imperial fief answerable to the Holy Roman Emperor while Schleswig was held as a Danish duchy, a constitutional tension that persisted for three centuries.
