Denier - Theoderich

Theoderich I of Basel held the bishopric during a period of intense friction between imperial and ecclesiastical power, and his coinage rights were exercised under the direct patronage of the Salian dynasty — Henry III confirmed and consolidated episcopal minting privileges across the Reich in the early 1040s as part of a deliberate policy of binding the church hierarchy to imperial authority. Basel's mint at this period struck in the Rhine Valley tradition, producing thin, bracteate-adjacent deniers whose survival rate is exceptionally low given the fragility of the flans.
