These forger’s dies were created to strike fake Solidi of RIC 104 Constantinus I for Constans Caesar (336/337 CE) and found in Beaumon-sur-Oise.
There should be an image in Gallica, but for the life of me I can’t put in the right key words to get the database to deliver the right record
BUT in someways I’m more interested in this single Gallic Die, because of how the shape of the die reminds me of the Republican die now in Madrid. (old post with photo; another post for context). The Madrid die will be fully published soon…

Yeah, we gotta figure out how to search Gallica. I always get stumped. Reminded me of a rabbinic story from Roman times about discovery of gold hoard in Antioch that we read at bedtime. It’s a story about hoarding: https://en.wikipedia.org/wiki/Abba_Judan
