Silver Unit Herringbone Spiral

The Iceni occupied what is now Norfolk and parts of Suffolk, operating a mint — or more likely several dispersed production points — that issued silver coinage in the final decades before Roman conquest. Their monetary system collapsed not with Claudius's invasion of 43 AD but earlier, through client-king arrangements that steadily subordinated tribal authority. This piece falls squarely in that transitional window, when Iceni silver was being produced under increasing Roman political pressure but before outright absorption.

ABC 1543 is among the more precisely classified Iceni units, distinguished by the herringbone spine treatment that differentiates it from related spiral-pattern varieties catalogued nearby in the Allen-Bateson-Chadburn sequence.
