Denier with rider AMBILLI / EBVRO

The AMBILLI inscription has generated genuine disagreement among Celtic numismatists — some attribute it to a tribal name, others to a moneyer or magistrate responsible for the issue. EBVRO, appearing on the reverse, is generally associated with the Eburovices or a cognate group, though its presence here in the Rhone Valley suggests either a wide territorial reach or, more plausibly, a minting arrangement between neighboring peoples during a period of intensifying Roman pressure on southern Gaul following the reorganization of Gallia Transalpina around 120 BC.
