Denier Bracteate - Conrad II of Tegerfelden

Conrad II of Tegerfelden served as Bishop of Constance from 1209 to 1233, presiding over a diocese that was among the largest in the medieval German church — stretching from the Rhine to well into what is now Switzerland. Bracteates of this type were struck as the thin, single-sided fabric became the dominant small-denomination coinage of the Upper Rhine and Swabian regions during the late twelfth and early thirteenth centuries, displacing the earlier double-sided denier almost entirely in this zone.

The Cahn corpus remains the foundational reference for Constance bracteate attribution, with Wüthrich's collection providing key die-link evidence for sequencing issues across Conrad's episcopate.
