Pépin le Bref's monetary reform of 755 — enforced by capitulary and backed by ecclesiastical authority — standardized the denier across Frankish territories, breaking from the fragmented Merovingian coinage system that had allowed local magnates and monasteries to strike essentially at will. The Nevers mint was among those absorbed into this new royal monopoly. At roughly 0.71g, these pieces fall below the theoretical standard Pépin attempted to impose, suggesting either local weight drift or tolerance practices that his administration never fully corrected before his death in 768.
