Denier - Theoderich

Theoderich of Basel held the see from 1041 to 1055, a period when the Bishopric's minting rights were firmly grounded in imperial grant — the right to strike coin at Basel had been confirmed by the Ottonian and early Salian rulers as part of the broader policy of delegating fiscal infrastructure to loyal ecclesiastical lords. This denier belongs to that administrative arrangement, not to any single dramatic event.

At 0.6 g, these deniers fall on the light end of mid-eleventh century Rhenish issues, consistent with the gradual weight reduction seen across episcopal mints of the Upper Rhine during this decade.
