1 Pfennig

Schweinfurt's copper pfennig of 1622 belongs to the chaotic wave of municipal emergency coinage that flooded the Holy Roman Empire during the Kipper- und Wipperzeit — a currency crisis so destabilizing that it contributed directly to hyperinflation in the early years of the Thirty Years' War. Cities, princes, and petty lords debased silver coinage aggressively, forcing municipalities like Schweinfurt to issue their own small copper pieces simply to maintain local trade when debased coins drove good ones out of circulation entirely.
