Potin Unit Blob and Line / Degraded Head Variety

Potin coinage in Britain was not locally invented — it arrived as a technology transfer from the Kentish channel trade networks, ultimately derived from Massaliote and Gaulish prototypes. By the time types like this one were being cast, the originating designs had passed through so many generational copies that the source imagery had become functionally abstract. This is a feature, not a defect: the degradation itself is chronologically useful, placing the piece late within the potin sequence.

Cast rather than struck, which is the diagnostic production method for all British potins. No mint, no authority, no issuer we can name with confidence.
