Silver 1/2 Unit Tricorne

The Iceni occupied what is now Norfolk and Suffolk, operating largely outside direct Roman administrative control until Prasutagus formalized a client-kingdom arrangement with Rome — an arrangement that collapsed catastrophically after his death when Roman officials seized Icenian lands and triggered the Boudiccan revolt of 60–61 AD. Coinage of this period reflects a tribe still managing its own affairs, issuing silver fractions for exchange within a network that probably included grain, livestock, and prestige goods rather than anything resembling a monetized market economy.

The tricorne designation refers to the die classification, not a visual description provided here. At 0.6 g, these fractions were easily lost and infrequently recovered intact — detector finds from Norfolk hoards account for the majority of known examples.
