Denier with hippocampus facing right

The Allobroges, a powerful Gallic tribe occupying the region between the Rhône and the Alps, were subdued by Rome in 121 BC following a campaign by Quintus Fabius Maximus — yet continued issuing their own silver coinage for decades afterward. This denier belongs to that post-conquest period of uneasy Roman accommodation, during which tribal monetary systems persisted alongside Roman currency rather than being immediately displaced.

The hippocampus type is among the more distinctive in Allobrogian coinage, and the die work on this series shows notably uneven execution across known specimens.
