Autograph Serial Key What Is The BEST Company To Get A COA For Sports Autographs From?

What is the BEST company to get a COA for sports autographs from? - autograph serial key

Signed With a view to buying a bullet from a friend for the holidays and you do not know the difference between a certificate of authenticity from another - the last of them looked at me with a certificate of authenticity from Global Authentication Inc. (GAI) and comes with a game -- Stick evidence of manipulation and serial number. Is this a good company and if it is not what the company is looking for autographs would happen if? Thanks
