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).
One of the rarest authentic autographed Mickey Mantle baseballs is one that is signed on a "Budig" baseball.
99% of Mantle signed "Budig" baseballs are forgeries.
They are all laughable and obvious forgeries also.
Check out the below forged Mickey Mantle "Budig" baseball listed by Ebay seller 2012ehrig.
The worthless COA is from Victoria Mertes.
The "autograph" is laughable at best.
Look at this crap.
It even includes a laughable inscription "NO 7."
Of course, there is bidding on it because Ebay is so heavily-populated with delusional autograph collectors, impulse buyers and scammers who flip garbage like that.
