Silver 1/2 Unit - Eastern North Thames Sudbury Snakeheads

The Trinovantes occupied territory roughly corresponding to modern Essex and southern Suffolk, and by the mid-first century BC were navigating increasing pressure from the Catuvellauni to the west. These fractional silver units — the "Snakehead" types named by modern collectors for their distinctive imagery — circulated in the lower Thames estuary region and likely functioned in small-denomination exchange within tribal markets rather than in any large-scale interregional trade. The Sudbury classification places this piece within a geographically defined die group identified through find-spot clustering and hoard distribution.

At under a gram, these were easily lost and rarely hoarded in quantity. Most known examples come from metal detector finds in Essex.
