Hello,
These coins are from the same seller on eBay and I haven’t been able to properly identify them so far. Any idea? I’d like some opinions on their authenticity if possible, though the seller is a rather trusted one. Maybe simply cleaned or such?
They are all genuine, but quite corroded and worn.
The #1 is indeed Provincial, and shows tyche on reverse but I couldn't tell more. Maybe someone with more experience in roman provincial coinage could recognize it.
The #2 could be a dupondius of Domitian, but I'm still struggling to decipher any character or depiction on the reverse.
The #3 is an antoninianus Claudius II with FIDES EXERCI on reverse. IMP C CLAVDIVS AVG on obverse. Your Fides seems to look right, if it's that so I cannot find an exact match in the RIC.
The #4 is a votive type for Constantius II. Reverse VOT XX MVLT XXX.
The #5 is for Constantine I, reverse VIRTVS AVGG, campgate type, PR across fields, mintmark possibly RP, rome mint.
The reverse of #2 looks rather hopeless to me...but thank you! I thought it was Nero at first but the head didn't quite match. Domitian is definitely closer.
