it's Aelia Flaccilla and the reverse is SALVS REIPVBLICAE; Victory seated right, inscribing Christogram on shield set on a column. I can't make out the mint though.
Hey I just got one of these from @Victor_Clark ..I'll give him a shout out for good service ....and photography. I couldn't beat your pic of the coin! Aelia Flaccilla A.D. 378- 383 AEL FLACCILLA AVG; draped, with elaborate head-dress, necklace and mantle. SALVS REIPVBLICAE; Victory seated right, inscribing Christogram on shield set on a column. In ex. SMHA RIC IX Heraclea 17 12mm 1.2gm I've been wanting to get a coin of her for years now.
