Immediately below, are just a few links to threads on Stephen Rocchi and Guaranteed Forensic Authenticators (GFA).

Since they started their sham operation nine years ago, I still have yet to observe one authentic autograph with their worthless COA.

Not one.

Check out these two forged and laughable Mickey Mantle and Roger Maris photos with worthless COAs from GFA and Stephen Rocchi sold by Ebay seller Sloguy2000.

These sold for $450.00 and $350.00.

You have to be a moron or delusional to think you purchased an authentic set of Mickey Mantle and Roger Maris autographed photos for those laughable prices.

Think about this; Roger Maris passed away in 1985; so how in the hell did he sign these photos on inkjet paper.

How about some freaking common sense.

On top of that, these are laughable forgeries.

Check on the serial numbers on the COAs:  71817 and 71818.

These are mass-produced forgeries out of Florida.
