Before I continue, below are links showing hundreds of examples of forged Mickey Mantle baseballs, photos, etc. found on Ebay (the most dangerous place to buy autographs if you're a casual collector or impulse buyer).
I was looking at the listing. Ball signed in the autumn of 1994? Lol. Yeah, ok. It says he's a top seller on there and he has a 30-day return policy. So, he either knows he selling a forgery or he's very naive. He also has a DiMaggio for sale that's also a forgery. Hmmmm
