Pfennig Undetermined Friesach marks

Friesach pfennigs were among the most commercially significant coinages in the medieval German-speaking world, circulating so widely across Central Europe and the Levant that "Friesacher" became a generic term for quality silver coin in regional trade documents. The Archbishop of Salzburg and the Dukes of Carinthia operated competing mints at Friesach simultaneously, producing superficially similar types that scholars spent generations attempting to attribute — the "undetermined marks" designation on this piece reflects that unresolved die study rather than any deficiency in the coin itself.

Luschin von Ebengreuth's foundational work on this series in the late 19th century remains the baseline for attribution, though the CNA corpus has since refined the typology considerably.
