Pfennig Undetermined Friesach minting

Friesach, in what is now southern Austria, operated as one of the most commercially significant minting centers in the medieval German-speaking world — its silver pfennigs circulated as far as the Adriatic coast and into the Balkans, where they became a de facto trade currency known generically as "Friesacher Pfennige" regardless of actual issuing authority. The attribution problem embedded in this piece's cataloging is genuine: the Archbishopric of Salzburg, the Duchy of Carinthia, and the Patriarchate of Aquileia all operated at Friesach concurrently, sharing dies and often the same moneyers.

CNA Cj53 places this squarely in the Carinthian series, but the overlapping production arrangements mean that even specialists working from the coins themselves frequently disagree on issuer.
