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).
When does a Mickey Mantle and Roger Maris autographed photo sell for $54.00?
When it's a laughable piece-of-crap set of forgeries.
Check out the below forged Mantle/Maris photo sold by Ebay seller Alsop_us for a whopping $54.00.
Does the person who bought this, really think they purchased an authentic set of Mickey Mantle and Roger Maris autographs for $54.00!!!
Crap like this sells because Ebay is so heavily-populated with delusional autograph collectors and impulse buyers.
Also, Ebay does not care. It is only about the money.
People have this pre-conceived notion that Ebay filters out forgeries.
Nothing could be further from the truth. Ebay makes a ton of money from the sales of forgeries.
