GFA opened its doors Sept. 2011.

That was almost 15 years ago.

During that almost 15 years, I have never observed an authentic autograph with a GFA (Rocchi) COA.

Not one in almost 15 years.

I just spotted this on Ebay.

Forged Mickey Mantle bat with a COA from Guaranteed Forensic Authenticators.

Look at this train wreck.
