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).

Also immediately below is a link to my blog on The Florida Forgeries.

Check out the below forged  Mickey Mantle and Willie Mays photo.  These are Florida Forgeries.

These are listed by Ebay seller Milwaukee--jon.

Now check this out.  

Ebay seller Milwaukee--jon has a so-called Steiner Sports COA coupled with these forgeries.   As you can observe this is not a Steiner Sports product.

Now here are the Mantle and Mays forgeries.

Check out the bottom right corner and observe the HPM Florida hologram.

HPM stands for Hall Of Fame Players Market; a Florida COA.

Not the sharpest tool in the shed to attempt to sell forgeries using a Steiner Sports COA, but not hide the Florida hologram.
