The Leuci were a Celtic people of eastern Gaul, settled in the region of present-day Lorraine, particularly around Toul and the upper Moselle valley.
Part of the wider La Tène cultural world, they occupied an important position between central Gaul and the Rhine frontier, benefiting from trade and communication routes across north-eastern Europe. Their chief centre later became the Roman settlement of Tullum Leucorum, reflecting their incorporation into the Roman world after the Gallic campaigns.
The tribe is also well known for its coinage, which belongs to the rich artistic tradition of late Iron Age Gaul. Leuci coins, often struck in potin, bronze or silver, typically display highly stylised motifs derived from earlier Greek and Gaulish prototypes, such as abstract heads, horses and other symbolic devices. These issues served not only as currency, but also as expressions of tribal identity and regional authority, illustrating the distinctive blend of Celtic artistry and external influence that characterises Gallic numismatics.
Potin is a cast copper-based alloy, typically containing varying proportions of copper, tin and lead, widely used for small-value coinage in Iron Age Gaul and Britain. Among the Celts it provided a practical and economical alternative to struck silver or gold, allowing tribes to produce coinage in larger quantities for everyday exchange.
Celtic potin coins are especially notable for their dark appearance, cast manufacture and often highly stylised designs, which reflect the distinctive abstract character of late Iron Age art.
