Pfennig - Werinto and Dietrich

Formbach was a small comital dynasty in the Inn valley whose minting activity peaked in the early twelfth century before the line died out in 1158, with territories absorbed by the Babenbergs. The joint attribution to Werinto and Dietrich — almost certainly co-ruling counts of the same house — narrows this piece to a decade when the county still held independent issuing authority, likely exercised through a mint at or near Vornbach am Inn.

CNA B37 is sparsely documented in auction records, which reflects the genuine rarity of attributed Formbach issues rather than collector indifference.
