I picked this one up pretty much because it's in such great condition. This was found locally (not by me) in Linconshire UK. I know it is constantine but that's as far as my knowledge of it goes. $20 I paid. A steal?
EDIT: I think it is this... Constantine I, 307-337 AD, AE3 - SOLI INVICTO Obverse: IMP CONSTANTINVS PF AVG laurateate and cuirassed bust right Reverse: SOLI INVITO COMITI Sol standing left with globe and raising right hand, chlamys draped over shoulder, PTR in exergue, T-F around Sol Daes to 310-313 AD Trier Mint, RIC 102 20mm, 3.00 grams
pulled mine out to see. I paid $7 for mine, but mines pretty worn , so I'd say yeah you got a great deal.
Congrats on this find! Wow. I have a strong interest in roman culture and coins, just have not made the leap. Once I am satisfied with my current obsession I will most likely make that leap. Once again, Congrats Regards SGT S
