'Troccos Bull' Bronze Unit 'Trinovantian U' - Trocc

The Catuvellauni, operating out of their principal centre at Camulodunum — modern Colchester — were the dominant political force in southeastern Britain in the decades immediately preceding the Claudian invasion of 43 AD. This small bronze unit belongs to a phase when the tribe was aggressively expanding at the expense of their neighbours, the Trinovantes, whose territory they had largely absorbed by this period. The "Trinovantian U" classification reflects a typological grouping rather than a separate issuing authority — these coins were struck by Catuvellaunian control over formerly Trinovantian lands.

The TROCC inscription remains incompletely understood; it may denote a mint site, a magistrate, or a subordinate authority operating under Cunobelinus.
