Pfennig - Henry IV Gutenwerth

Henry IV of Istria and Carniola issued these bracteate-style pfennigs during a period when the March was caught between competing imperial and Venetian pressures along the Adriatic hinterland. The Gutenwerth mint — on an island in the Wörthersee — was one of the few active striking facilities in the region, and its output during this window represents nearly the entire surviving coinage attributable to Henry's march.

The CNA Cj3 attribution places this firmly within Castelin's typology for the region, a reference that remains the primary authority for Carinthian and Carniolan issues of this period.
