Denier - Rudhart

The Bishopric of Constance was among the most powerful ecclesiastical territories in the early German kingdom, and its coinage rights under the Salian and earlier Ottonian rulers were tied directly to royal favor rather than any permanent grant. The deniers attributed to this brief window under Bishop Rudhart — who held the see from 1018 to 1022 — represent one of the shortest episcopal minting episodes in the diocese's history.

Kluge's cataloguing places this type firmly within the Karolingian-derivative denier tradition still circulating across the upper Rhine region at this date.
