Pfennig - Berthold V of Aquileia Gutenwerth

Berthold V, a Bavarian-born Andechs duke who held the Patriarchate from 1218 until his death in 1251, issued coinage from Gutenwerth — a mint site on an island in the Drava River in present-day Slovenia — during a period when the Patriarchate wielded genuine secular authority across Friuli and much of the eastern Alpine frontier. The narrow 1220–1228 window for this type reflects shifting political pressures from the Habsburgs and the commune of Treviso rather than any change in ecclesiastical tenure.
