Silver 1/2 Unit Allen ZB

The Corieltauvi occupied a substantial territory across what is now Lincolnshire, Leicestershire, and Nottinghamshire, and are unusual among British Iron Age tribes for apparently operating without a single paramount ruler — their coinage shows paired and sometimes triple name combinations suggesting shared or collegiate authority. The "Allen ZB" classification follows D.F. Allen's foundational typological work on Celtic British coins, which remains the baseline for Corieltauvian series despite subsequent refinements. At half a gram, these fractional pieces served real transactional functions, most likely in high-value exchange among elites rather than everyday commerce.
