How about this one? Surface looks original. http://www.ebay.com/itm/1945-MERCUR...29?pt=Coins_US_Individual&hash=item53eeba30a9
Something about this dime looks off to me. Looks kinda rough under inspection. http://www.ebay.com/itm/1943-MERCUR...52?pt=Coins_US_Individual&hash=item564d5cecec
The second looks like a nice original coin, The third coin has a juiced image. I would stay away from the third one simply because it is too hard to tell if it has been tampered with.
