Potin with large laureate head DOCI

The Sequani occupied the territory of modern Franche-Comté and were among the more politically active Gallic tribes of the late Republic period — they famously invited Ariovistus and his Germanic forces across the Rhine around 71 BC to gain leverage against the Aedui, a decision that ultimately contributed to Caesar's justification for intervention in Gaul. Potin coinage of this type was cast rather than struck, a production method increasingly marginal by this period even among Gallic issuers.

The DOCI inscription is generally read as a magistrate name or tribal authority marker, though its precise administrative significance remains debated among Celtic numismatists.
