I see that now. However, the obverse legend is IMP C CONSTANTINVS P F AVG as far as I can tell. I can't find one with this reverse. The extra C in the legend is not that frequent.
I agree ....I've just been through tesorillo and there's no match! Maybe one the experts has a reference for this...but it doesn't seem common.....Maybe a I'm missing something?
One of these here. (EDIT: More specifically, I think it's RIC VI Rome 313.) I read the mintmark as "RP" – if that's correct, it's from the Rome mint, first officina.
I'm going with this one. Please take a look and give feedback. RIC VI Rome 339 Date AD 312 - AD 313 Denomination AE2 Mint Rome Obverse IMP C CONSTANTINVS P F AVG: Bust of Constantine I, laureate, cuirassed, right Reverse SOLI IN-VI-CTO COMITI or SOLI INV-I-CTO COMITI: Sol, chlamys hanging behind (sometimes flying out), standing right, raising right hand and holding globe across body in left hand
I initially thought the same, but the problem with this attribution is that your coin clearly shows Sol holding a whip in his left hand/arm. RIC Rome 339 isn't supposed to have a whip. I thus think your coin is RIC Rome 313 or a variety thereof.
I don't see an option for the chlamys flying in Rome 313 313 says - "chlamys hanging behind, standing left, raising right hand and holding whip in left hand" There are enough questions to think it may be yet a different variety
Whatever attribute I select it must have the whip and the chalmys sometimes flying out. Thanks for all the feedback and help.
The position of the globe and the spacing of the letters in Soli Invicto Commiti make a difference. Look here.
