A significant Celtic sanctuary, the site at Ribemont-sur-Ancre (Somme) is also an important Roman settlement, noted since the mid-sixties for its impressive architecture and remarkable urban planning. Numerous synthetic articles have documented the site’s installations, but paradoxically, the material unearthed has been the subject of only very scarce publications and remains largely unpublished. Since 2010, the data have been subject to a new examination, and the study of the material has been re-launched; this is the case for Roman coins, which until now had not been the subject of in-depth re-search and whose publication was limited to a simple listing covering only the discoveries from 1990 to 2003, while the corpus of species unearthed previously remained mostly unpublished. This article presents the coins discovered during the excavations of the years 1966-1989, carried out in the very heart of the agglomeration. They constitute sources of primary importance and particular interest to the variations in production and monetary supply of the site. Although the classification of coins according to their archaeological layer of provenance can only be imperfectly undertaken, the various excavation campaigns have brought to light numismatic material distributed between different districts of the agglomeration (theatre, baths, sanctuary, and habitats) which can be compared with each other to restore the characteristics of monetary circulation from the High to the Late Empire.
