Charenton in this period was held by a succession of minor lords whose coinage rights derived from grants predating the Capetian consolidation of the Île-de-France. The William named in Billon issues of this type is generally identified as Guillaume de Charenton, whose lordship fell within the orbit of the Bishop of Paris — a jurisdictional proximity that periodically created friction over minting privileges. Billon deniers from such small seigneuries rarely survived heavy circulation; the alloy was frequently debased enough that neighboring markets discounted them against royal issues.
