Denier - Conrad IV

Conrad IV served as Bishop of Regensburg from 1204 to 1226, a tenure that overlapped directly with the civil war between the Hohenstaufen and Welf factions for control of the Holy Roman Empire. Regensburg's ecclesiastical mint operated under imperial concession, and the bishop's coinage rights were periodically contested during this period of fragmented royal authority.

At under half a gram, these bracteate-era deniers from the Bavarian episcopal mints are among the lightest silver issues of the region — a reflection of progressive weight reduction across German ecclesiastical coinage through the early thirteenth century.
