Pfennig - Dietrich or successors

Formbach's comital line ended abruptly when Count Ekbert II died without male heirs around 1158, triggering a fragmented inheritance dispute that drew in the Bishopric of Passau and the House of Andechs. Coins attributable to this transitional period — struck under Dietrich or whichever successor briefly controlled the mint — are notoriously difficult to assign with precision, which is why the CNA catalogers hedged the attribution rather than commit to a single issuer.

The county itself was absorbed into Bavarian ecclesiastical territories within a generation of this issue.
