Pfennig Undetermined Friesach minting

Friesach, in the Salzburg archdiocese, was among the earliest and most prolific silver minting centers in the eastern Alpine lands, and the so-called Friesacher Pfennig became a dominant trade currency across the central Danubian region from the late 12th century onward. Jurisdictional claims over minting rights in Friesach were bitterly contested between the Dukes of Carinthia and the Archbishops of Salzburg throughout this period — attribution of individual issues to one authority or the other remains unresolved for many dies, hence the "undetermined" assignment here.
