Potin Unit Curved Bull / Holman B2

Potin coinage among the Kentish Cantii derives ultimately from Massaliote bronze issues, transmitted through Gaulish intermediaries before being adopted and locally cast — not struck — in Britain. The Holman B2 classification distinguishes a specific casting variant within the broader "curved bull" series, reflecting the tribal practice of producing coins in clay molds rather than with dies, which is why no two examples are precisely identical in weight or outline.

These are among the earliest coins produced in Britain, predating Caesar's invasions by several decades and any Roman administrative influence entirely.
