I know for sure that this is a Sales reipublicae, but is this Amelia flacillas issue? Feel free to post yours
The obverse legend appears to have - CIL.. on the right which should make it an Aelia Flaccilla ae4 coin with the SALVS REIPVBLICAE reverse. If it's a small bronze around 13mm in diameter that's it.
Looks like Brian is right. Aelia Flaccilla ( 379 - 386 A.D.) Æ2 O: AEL FLACCILLA AVG, Diademed and draped bust right. R: SALVS REIPVBLICAE, Empress standing with hands folded on her chest. SMKr" in exergue. 5.5g RIC IX 14
Yes, it is Flaccilla. Constantinople mint, officina E. It's RIC61 (if small module 12-13mm. If larger module, RIC55).
I believe my coin's hair matches. This is an RIC 61 page 229 0.9g 12mm (AE4). Finding these Constantinople mint AE4 coins in full legend may not be all that easy (unless the ones online are hiding from me). My Siscia is more full. Who has a nice CON? Yours is not all that bad but deserves a better photo. Also CONE, my AE2, 3.9g is RIC 55 is double struck confusing the reverse but the hair is a bit different. I'm surprised that the Bruck book did not give us a key by mints to her hair styles. She had so many.
