Silver Unit - Regni Tangmere Two Horses

The Tangmere Two Horses type is associated with the tribal zone around modern West Sussex, a region where Atrebatic influence was consolidating in the decades immediately surrounding Caesar's two expeditions to Britain in 55 and 54 BC. Whether those invasions disrupted local minting or merely coincided with a shift in type is unresolved, but the coinage of this period shows marked fragmentation — multiple short-lived types issued in tight geographic clusters, suggesting political instability at the chieftain level rather than centralized production.

ABC 689 is among the scarcer Atrebatic silver units. Findspot evidence clusters heavily around the Chichester plain.
