Potin Unit Rounded Bull / Holman D2

Potin coinage among the Cantii emerged from Continental practice — specifically the Massaliote tradition transmitted through cross-Channel trade networks — and this type predates the Roman conquest by nearly half a century. The casting rather than striking of these pieces reflects the technology available in southeast Britain at the time; potin units were made in strip-cast chains and broken apart, which is why so many examples show irregular flans and casting flash at the edges.

Van Arsdell's sequencing places this D2 variety within a typological progression that helps archaeologists date southeast British sites. Several examples have been recovered from Thames foreshore deposits.
