Silver 1/2 Unit - Eastern North Thames Double Horse

The Trinovantes occupied territory roughly corresponding to modern Essex and southern Suffolk, and by the mid-first century BC were under mounting pressure from the expansionist Catuvellauni to the west. This fractional silver unit belongs to a period when Julius Caesar's two expeditions to Britain — 55 and 54 BC — were actively disrupting tribal power structures along the Thames estuary. Whether the coin predates or postdates Caesar's campaigns is unresolved, but its production almost certainly reflects a moment of political instability in which the Trinovantes were simultaneously resisting Catuvellaunian encroachment and, per Caesar's own account, appealing to Rome for protection.
