Potin with boar Class Io

The Leuci occupied territory in what is now Lorraine, centered around the Moselle valley, and maintained enough political independence to strike their own coinage well into the late Gaulish period. Potin — a cast tin-lead-copper alloy rather than struck metal — was the dominant monetary medium among several Belgic and eastern Gaulish peoples, and the Leuci Class I series is among the more consistently produced regional types. Julius Caesar names the Leuci explicitly in the *Bellum Gallicum* as a people subject to the Treveri's influence, which places this coinage squarely within a politically volatile frontier zone during the Gallic Wars.
