1 Mariengroschen - Reinhard II of Buchholtz

Corvey's right to mint was contested for much of the sixteenth century, with the abbey's coinage authority technically derived from a medieval imperial grant that secular neighbors repeatedly challenged in the Reichskammergericht. Reinhard II held the abbacy for only two years before his death in 1561, making this mariengroschen one of the briefest-tenured issues in the Corvey series.

The Ilisch Münster attribution places this piece within a documented die study, with the A/b designation indicating a specific obverse-reverse pairing rather than a general type.
