Pfennig - Frederick II, Gutenwerth

Frederick II of Austria — "the Warlike" — spent much of his reign in open conflict with Holy Roman Emperor Frederick II, a confrontation that ended with the Austrian duke's excommunication in 1236 and the imperial seizure of his territories. Coinage continued regardless, issued from Gutenwerth, a mint site on an island in the Wörthersee in Carinthia operating under ducal authority. Frederick was killed at the Battle of the Leitha in 1246, dying without a male heir and extinguishing the Babenberg line entirely.
