Stater 'Trinovantian M' - Tasciovanus

Tasciovanus ruled the Catuvellauni from a base at Verulamium — modern St Albans — and was among the first British tribal rulers to place his name on coinage, a practice borrowed directly from Gaulish contacts across the Channel. The 'M' series designation groups a cluster of issues distinguished by die-linking patterns rather than any single mint mark, and the attribution to Tasciovanus rests largely on find-spot distribution concentrated in Hertfordshire and Essex.

The Trinovantes, neighbours and sometime rivals to the Catuvellauni, likely fell under Tasciovanian dominance during this period — which complicates any clean attribution of findspot evidence to a single issuing authority.
