I do not think it is from the photos, the clash mark from the talons to the rim and from the "8" to the rim appear to be missing.
Yes, it should. You can see the clashes here I mentioned above. I think NNC missed on this one, and if you google them, that was the normal event.
I ask the seller to double check it but he just blew it off. It's not that hard to check but what do I know. It would be a $2000+ coin if real.
Why would he be auctioning a real 57 snow-7 on ebay rather than a real auction house that could document it? .....Because they would try to document it correctly. I guess some would play , thinking they could get it back if they were wrong.
Looks like the seller is going to go ahead and sell it. Based on the price as of now, few are being fooled by the listing or the slab. http://www.ebay.com/itm/381429817789?_trksid=p2060353.m1438.l2649&ssPageName=STRK:MEBIDX:IT
