Obol - Charles II Orleans mint

The 864 Edict of Pistres was Charles the Bald's attempt to rationalize a Carolingian monetary system that had fragmented badly under pressure from Viking raids and local magnates striking unauthorized coin. The edict restricted minting rights to specific royal palaces and episcopal centers — Orléans among them — and mandated the withdrawal of all earlier types. Obols from this reorganized phase are inherently short-lived issues; the window between the edict and Charles's death in 877 is narrow, and actual striking at any single authorized mint occupied only a fraction of that span.
