Stater

The Ambiani occupied the Somme valley in what is now Picardy, and their gold coinage — including this stater — was likely minted in significant volume to pay mercenary troops serving in the various inter-tribal conflicts of the late Gaulish period. Caesar's campaigns after 58 BC disrupted production across the region catastrophically; issues struck after roughly 57 BC are generally associated with a tribe already under severe military pressure. The alloy reduction from earlier Macedonian-derived prototypes reflects either deliberate debasement or constrained access to bullion as Roman encroachment tightened.
