I just received this coin a few days ago in a group of 3 antoninianii I bought from an auction on Forvm. This one seems interesting. I think I have the attribution narrowed to the following 2 possibilities. Please let me know if you think it is one of these or even a different coin entirely. My question is this: Is there a modius on the head of the genius on the reverse? Thanks in advance. Claudius II Gothicus, AE antoninianus. Rome. IMP CLAVDIVS AVG, radiate head right / GENIVS EXERCI, Genius standing left, modius on head, holding patera and cornucopiae. Cardiff, Llanedeyrn I hoard IARCW 318/44; RIC V-1, 49 var Claudius II Gothicus AE Antoninianus. Rome, 268-270 AD. IMP C CLAVDIVS AVG, radiate draped bust right / GENIVS EXERCI, Genius standing left, holding patera and cornucopiae. RIC V-1 48, Sear5 11340.
I don't think it is RIC V-1, 49 var since there should be a Z in the right field. I also think there is spacing for the letters on the obverse legend to read "IMP C Claudius AVG". You are in the ballpark, but looking through wildwinds, there are a couple of possibilities. Since I do not see a cuirassed bust that would leave only RIC 45 or RIC 48 rad,dr. In this condition, I think it's a take your pick decision unless someone else sees something I don't.
Genius usually has a modius on his head. Your coin is RIC 48, take a look here and skim through the examples listed: http://www.ric.mom.fr/en/coin/229
For future reference, using RIC Temp (for 268-276AD) is really easy and quite extensive. Chances are that if you have a coin from that time frame you'll find it there. It's a way more reliable reference source than RIC.
Thanks Seth, I am really not used to coins of this period, my main focus is the first century. I bought this one as part of a group of 3 because I liked the look of it and the group was very inexpensive. I appreciate the advice.
