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).
Check out this forged Mickey Mantle baseball listed by Ebay seller Wmhen-55.
This seller is not the sharpest tool in the shed.
Let's check out his "PSA authenticated" baseball.
Here is a photo of the "Mantle."
Obvious forged Mantle.
And the "Mantle" is on a "Budig" baseball.
Then Ebay seller Wmhen-55 posts a photo of the PSA sticker on a "Bobby Brown" baseball even though the seller describes it as "JSA" certified in the auction description, while the title reads "PSA."
This is laughable.
Here is a screenshot of some of the auction description.
You can click your mouse on the image to get a closer view.
The seller writes "Mickey Mantle JSA signed American League Baseball Autographed LOA certified. Hand signed."
