Denier - Theoderich

Basel's episcopal mint operated under a series of imperial grants, but the specific authority to strike coinage during this period derived from privileges confirmed under the Salian emperors. Bishop Theoderich I held the see from 1041 to 1046 — the attribution spanning to 1055 likely reflects die use continuing under his successor, a not uncommon practice at minor Rhenish and Upper Rhenish ecclesiastical mints where dies were expensive to replace and supervision was loose.
