Potin Unit Rounded Bull / Holman D7

Potin coinage among the Cantii was not minted in any conventional sense — these pieces were cast in clay or stone moulds, likely in small batches, producing the irregular flans and surface porosity that define the type. The Holman D7 classification within this series reflects a specific die grouping identified by numismatist John Holman in his systematic study of Kentish potin, separating what earlier cataloguers had lumped together under broad typological headings.

Cast rather than struck, these circulated across what is now Kent during a period of intensifying cross-Channel contact with Belgic Gaul — the alloy itself imitating, at some remove, the bronze coinage of Massalia.
