1 Groschen - Albert of Hohenzollern

Albert of Hohenzollern served as the last Grand Master of the Teutonic Knights to rule Prussia as a monastic state. In 1525, under pressure from Luther — whom he had consulted directly in Wittenberg — Albert dissolved the Order's Prussian branch, converted to Lutheranism, and transformed the territory into the secular Duchy of Prussia under Polish suzerainty. These groschen, struck across the final years of his Grand Mastership, were among the last coins issued under the Order's authority before that transformation permanently ended seven centuries of Teutonic governance in the region.
