Plotina (Augusta, 105-123). Æ Sestertius (34mm, 28.95g, 6h). Rome, c. 112-7. Draped bust r., wearing stephane. R/ Fides standing r., holding grain ears and basket of fruits. RIC II 740 (Trajan). Fine Just doing a random search through previous auctions today, I noticed what appears to be the same coin (shape and pitting patterns are identical) from the same auction house in 2016, but with different features, surface colour and markings. Plotina (Trajan, 98-117), Sestertius, Rome, AD 112-117; ; PLOTINA AVG - [IMP TRAIANI], diademed and draped bust r., hair in long tail at back, Rv. FIDES - [A]VGVS[T], Fides standing r., holding corn-ears and basket of fruit; in field, S - C. RIC 740; C 12.Rare. Large flan, dark patina, very fine. There was no mention of smoothing in my purchase and I'm a bit of a newbie (advice is maybe to stay away from more expensive coins till I know better). Is it the same coin? What alterations have been made? Do you think I should return the coin, or contact the auction house?
