Silver Unit S-Type Proto Boar with Spear

The Corieltauvi occupied a territory roughly corresponding to modern Lincolnshire, Leicestershire, and Nottinghamshire, and their coinage is notably unusual among British Celtic issues for frequently bearing paired names — interpreted by scholars as evidence of joint rulership rather than sequential reigns. The S-Type classification places this unit within an early phase of Corieltavian silver production, before the tribe's output became more standardized in the decades approaching the Claudian conquest.

No Roman military pressure directly triggered this coinage — Caesar's expeditions of 55 and 54 BC reached no further than the Thames valley, leaving Corieltavian territory untouched and its mint activity driven by internal economic and political forces rather than Roman disruption.
