Potin Unit Rounded Bull / Holman E5

The Cantii occupied the southeast corner of Britain — roughly modern Kent — and their potin coinage represents one of the earliest indigenous struck or cast currencies in the British Isles. Potin itself, a tin-rich bronze alloy, was the material of choice for these small cast pieces, which owe their form ultimately to Massaliote prototypes filtered through generations of Gaulish transmission. By the time the Cantii were producing their own types, the originals had been abstracted almost beyond recognition through successive copying.

Caesar's two expeditions into Cantii territory in 55 and 54 BC postdate this issue by at least a decade, meaning these coins were already circulating when his legions first encountered the tribe.
