Denier - Charlemagne Saint Fermin church of Amiens, CAROL REX

Struck in the earliest years of Charlemagne's sole reign over the Franks — before the execution of his brother Carloman's heirs had fully consolidated his authority — this denier belongs to the initial phase of Carolingian monetary reform that would eventually standardize silver coinage across much of western Europe. The Amiens mint operated under episcopal oversight, with the church of Saint-Fermin providing both the institutional authority and the physical infrastructure for striking. These earliest Carol Rex issues predate the heavier reformed deniers mandated after 793-794, making them measurably lighter than later Carolingian production.
