Silver 1/2 Unit Tricorne / Plouviez Tricorne

The Iceni occupied what is now Norfolk and Suffolk, and by the late first century BC were operating within a sophisticated inter-tribal exchange network rather than a fully monetized economy. These small silver fractions — sometimes called "minims" — were likely used in high-value transactions by weight or count rather than face denomination. The Snettisham and Plouviez die groupings identified by Richard Hobbs and others suggest production at more than one location, possibly reflecting decentralized authority among Iceni subtribes before the consolidation under rulers like Antedios and, later, Prasutagus.
