Silver Unit - Berkshire Abingdon Head

The Atrebates occupied territory spanning modern Berkshire, Hampshire, and Sussex, and by the mid-first century BC were absorbing significant Continental influence through trade and migration from the Belgic Atrebates of Gaul — Caesar's campaigns against those same Gaulish tribes almost certainly disrupted those networks directly. The "Abingdon Head" type takes its name from the findspot concentration around the upper Thames valley, suggesting a northern distribution zone for Atrebatic coinage distinct from the tribe's political heartland further south.

ABC 1007 belongs to a fractional denomination tradition typical of late Iron Age silver issues, where small units likely facilitated localized exchange rather than large-scale tribute payments.
