Denier - Anonymous

The Bishopric of Basel exercised temporal coinage rights granted under the Holy Roman Empire, with episcopal mints operating with considerable autonomy throughout the twelfth century. Anonymous attribution on these deniers was standard practice — not evasion, but simply the convention of an era when the issuing institution, not a named ruler, carried monetary authority. HMZ 1#203 places this piece within a documented Basel type, though the absence of a named prelate makes precise dating within the fifty-year window genuinely difficult. The thin flan and low silver content reflect the broader debasement pressures affecting Rhenish ecclesiastical coinages after roughly 1160.
