Lets say I have a Mickey Mantle game used bat for sale and I 100% guarantee its authentic. Well, the new owner sends it in to get it authenticated and they say they cannot because it doesnt match up to Mantle's characteristics, but one of his teammates, like Harry Bright.

Now, would you want a authentic Mantle bat used by Harry Bright? I know I wouldnt for the money one would probably drop on it. Because its not a game used Mickey Mantle bat. Just like you had your bat used by that particular player.

Pretty much, you didnt sell the guy the same item you had listed in the auction. Yes, it was an authentic John Doe bat.....I guess. But used by John Doe, well, Taube answered that question for ya. Really, I dont think its that difficult. Like I said, Id be pissed too and would want a refund.
