Denier - Otto III Andernach mint, city wall

Otto III inherited the throne at age three following his father's sudden death in 983, leaving the empire under a regency — first his mother Theophanu, then his grandmother Adelaide — until he came of age. The Andernach mint was one of several Rhenish mints active under his reign, operating under royal grant in a strategically positioned town along the Rhine. Andernach's minting rights had deep Carolingian roots, and Otto III's issues there continued that administrative continuity rather than marking any new monetary initiative.

Kluge's classification places this among a group of deniers whose city-wall reverse type was closely tied to specific grant-holding ecclesiastical or comital authorities at individual mints.
