Friesach, a market town in upper Carinthia, became the dominant minting center for the eastern Alpine trade network from roughly the mid-twelfth century, and the silver penny type it produced was so commercially trusted that "Friesacher Pfennig" became a recognized unit of account across Slovenia, Croatia, and Hungary well into the thirteenth century. Attribution within this series is notoriously difficult — multiple episcopal and ducal authorities struck coins to the same weight standard at Friesach and surrounding sites, and the CNA Cj32 grouping reflects that unresolved issuer problem rather than any deficiency in the individual specimen.
