This particular coin isn't worth very much but I had completely forgotten about it until earlier today. I bought it what must have been months ago and it got stashed away in a storage box (coin storage box) with the intent of looking at it but it slipped my mind. The toning on this was the only reason I had bought it, and I think I paid about $1 for it. Anyways... look at the colors! It almost looks like an AT coin but it just say in one of those cardboard flips for who knows how long? I'll see what it looks like in the sunlight in a few days, hopefully.
Yours looks like it has had a polish in the past, it definitely has altered surfaces. coins with altered surfaces do not tone in the same colors, so not necessarily AT as much as AS. Here is a worn Buffalo that has natural surfaces. I bought it for the D/S
