Long-necked potin

Potin — a cast tin-bronze alloy — was never struck from dies in the conventional sense; these pieces were produced in clay or stone moulds, often in connected strips that were snapped apart, leaving the characteristic irregular flan edges seen on most survivors. The "long-necked" type takes its name from a modern typological convention, not any ancient designation. Attribution to specific Rhone Valley tribes remains contested, with no surviving literary or epigraphic source confirming the issuing authority.
