Denier - Charles II / Charles III Le Mans mint

The Edict of Pîtres in 864 was Charles the Bald's attempt to reassert royal control over a coinage that had fragmented badly — local lords and ecclesiastical authorities had been striking on their own terms for decades. The edict designated specific authorized mints, Le Mans among them, and made unauthorized minting a capital offense. Whether it worked is another question entirely; enforcement was patchy at best, and the same types continued under Charles III with little administrative interruption despite the dynastic turbulence of 888–898.
