Since the inception of Stephen Rocchi and Guaranteed Forensic Authenticators in Sept. 2011, I have yet to observe on authentic autograph with their COA.
Their so-called "Forensic Examination" is just a bunch of BS and the real hobby knows it.
GFA (Guaranteed Fake Autograph) and their bullcrap is directly at people who believe that "Forensic BS" when it comes to autographs.
I have probably posted hundreds of threads/blogs on GFA and will continue to do.
Look at this laughable (forged) "Mickey Mantle" with a worthless COA from GFA and listed by Ebay seller Nova234.
