Zinsgroschen - Frederick III, John and George

The Ernestinian line's joint coinage arrangements were a direct consequence of the Saxon division of 1485, the Leipzig Partition that split the Wettin dynasty into two branches and required complex negotiations over shared monetary administration for decades afterward. Frederick III — Frederick the Wise — was the Elector who sheltered Martin Luther at the Wartburg following the Diet of Worms in 1521, meaning this type was actively circulating during the most convulsive years of the early Reformation. The billon content reflects the broader debasement pressures on central European groschen coinage in the early sixteenth century, as silver supplies from the Erzgebirge mines were increasingly strained by demand.
