I'm wondering if someone could help me out with this one. I bought this yesterday at a local antique mall. Being new to coin collecting, I'm still having trouble telling the difference between post-mint damage and the different kinds of mint errors or die varieties.
I think someone on
ebay is trying to sell the same kind of dime for a lot of money, but even that person doesn't know what's going on, so any help would be much appreciated.

I have a couple more images, but don't know if they'll help at all. Thanks.
