3 Pfennig - Frederick II

Frederick II of Mecklenburg-Schwerin ruled through the catastrophic aftermath of the Seven Years' War, which left the duchy's finances severely depleted from occupation, requisitions, and troop movements across its territory. Small billon issues like this one were the workhorse of everyday transactions in a state struggling to rebuild its monetary circulation. The .187 fineness — barely silver by any measure — reflects how thin the duchy's resources were stretched during this period.
