Gratian AE3. 367-383 AD, Siscia mint, 2.3g, 18mm OBV: DN GRATIANVS PF AVG, Pearl-diademed draped & cuirassed bust right. REV: GLORIA RO-MANORVM, Emperor walking right, head turned back, holding labarum and dragging bound captive behind him. S over dot in left field; A over sigma in right field; Delta SISCE in ex. REF: RIC IX Siscia 14v This coin is a recent purchase along with some of the other late Romans. The number of workshop marks for this coin just staggers the mind. There are it seems like hundreds of them. Perhaps this one might be unlisted but most of them seem to be lumped into RIC IX Siscia 14, so I'm stating the catalog as that unless someone disagrees or finds a exact match for this coin. Wikipedia copy and paste history.
