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've haven't observed one of the below COAs in years.
A "Smokey's Sportscards" COA with a laughable forged Mickey Mantle baseball.
Smokey's, of course, was a major part of Operation Bullpen.
Ebay seller Micma434009 has this garbage listed with a $2,000 Buy It Now/Best Offer.
Even the delusional autograph collectors and impulse buyers that heavily-populate Ebay, won't buy this crap.
