Pfennig - Berthold II von Pfirt

Berthold II von Pfirt served as Bishop of Basel during a period of intense friction between episcopal authority and the burghers of the city, culminating in conflicts that would eventually strip the bishops of direct urban control. His coinage draws from the broader Upper Rhenish bracteate tradition, struck thin enough that the die impression reads through to the reverse — a production method that kept silver content low while maintaining a workable flan at minimal minting cost.
