1 Kreuzer - Frederick III Graz

Frederick III issued this kreuzer from Graz during the final years of a reign defined by chronic financial embarrassment and near-constant siege — most famously when Matthias Corvinus of Hungary occupied Vienna in 1485 and held it for five years, forcing the Habsburg court to operate from Styrian strongholds. The Graz mint became correspondingly more active during this period out of sheer administrative necessity.

At 0.69 g, these small silver pieces were already below the theoretical kreuzer standard, reflecting the steady debasement that plagued Habsburg petty coinage through the 1480s.
