Denier - Pepin I bust and temple

Pépin I of Aquitaine received his sub-kingdom from his father Louis the Pious in 817, the same year Louis issued the Ordinatio Imperii — a document restructuring Carolingian succession that made Pépin's position nominally secure but ultimately subordinate. This denier, struck just a year later, is among the earliest issues of his reign and reflects the Carolingian monetary reform initiated under Charlemagne, which standardized the silver denier across Frankish-controlled territories. Pépin's Aquitanian issues are catalogued under multiple overlapping reference systems precisely because the regional minting administration remained administratively distinct from the imperial core.
