The "no return policy" carries no weight if the item isn't as described. If it's not a legit 1926-S XF45 in a legit NGC slab saying so, it's Significantly Not As Described, and the buyer is off the hook (assuming they pursue it).
As @TypeCoin971793 pointed out, the same coin was sold in August. It went for$763.33, sold by the same person that's selling it now. Obviously it was returned.
I finally got a reply from the seller. They didn't send any clearer pictures but did send the certification number of 1807365-007 which does verify at NGC for an XF-45 1926-S Buffalo nickel. That said, I probably got a response since the bid is only up to $104.50 with less than 24 hours to go.
Now that we have some of the above information/confirmations, my answer to "Who would bid on this 1926-S Buffalo nickel?" is, "I would.", you might just end up getting a bargain.
And if it isn't the genuine NGC XF45 example with that cert #, you've got an ironclad Buyer Protection case.
Even though I want one like that for my Dansco album I couldn't justify the risk. There had to be a reason for the bad images. I hope the winning bidder is a CT member and saw this thread and will fill us in on the details once the coin is in hand.
