Oh, my. What happened, little Seated Liberty Dime? Did someone hurt you!? I looks real enough. Hard to tell with photos and condition. If it is real, it contains about $1.70 of silver. I think that is 1886; that's not 1866, is it? No, I don't think so. Yeah, that's '86, right? I cannot make out a mint mark, so I am leaning toward Philadelphia. In 1866, Philadelphia minted 8,725 of those; plus 725 proof. Pretty rare, I'd say. In 1886, Philadelphia put out 6,377,570; plus 886 proofs. Not horribly rare, but it appears folks are putting out more than a few bucks for the same in Good condition.
