I am a long time collector of modern world coins but started branching out to other types about ten years ago. I purchased this coin from a seller that was moving large quantities of coins as part of closing down an inherited LCS. This coin was listed simply as "unidentified". I have no idea if it is even genuine. It weighs 12.89g, about 27mm. Your feedback would be greatly appreciated.
I don't see any reason to doubt the authenticity. Hadrian A.D. 119-123 Æ Dupondius IMP CAESAR TRAIAN HADRIANVS AVG P M TR P COS III; radiate and draped bust right. FELICITA S AVGVSTI; Felicitas standing l., holding caduceus and cornucopia; across fields S - C. RIC II Rome 611
