Here is a horrific forgery listed by eBay seller gaylynnegan67 who puts "AUTHENTIC" in the title, unfortunately this couldn't be further from the truth.

BIN of $685 which just shows you how clueless these moron sellers are. You can get a snow white AUTHENTIC Mickey Mantle signed ball Upper Deck certified for $500. LOL.
