Potin with helmeted head and ringlet

The Senones occupied a swath of central Gaul roughly corresponding to modern Seine-et-Marne and Loiret, and their potin coinage was in active production during the years Caesar was systematically dismantling Gaulish resistance. Potin — a cast tin-lead-bronze alloy rather than a struck metal — was the workhorse small change of northern and central Gaul, cheap to produce and apparently acceptable across tribal boundaries. The date range here brackets the revolt of Vercingetorix and the catastrophic siege of Alesia in 52 BC, after which independent Gaulish monetary production effectively ceased.
