1 Groschen - Christoph

Christoph of Württemberg struck this groschen during the period when he was consolidating Lutheran reforms across the duchy — the same years he was negotiating the Treaty of Passau's practical implementation with Protestant estates. His mint at Stuttgart was producing coinage in quantity to fund an administration simultaneously rebuilding ecclesiastical infrastructure and managing the return of properties seized under the Habsburgs during his predecessor's reign.

The .500 fineness places it squarely in the debased regional standard common to southwestern German territories by mid-century, when the fragmentation of minting authority made consistent silver content across the Holy Roman Empire essentially unenforceable.
