So I had to learn a lot about certificates, who's are legit, what to look out for, how to check for fakes.
All I can say is your best off never spending $ on this stuff. Market is completely flooded with fake stuff. These certificate companies are complete bs, corrupt as hell, and really don't do much.
I remember one time we were suppose to get a game worn farve jersey. Paid a nice penny for it, shows up with the certificate and all. Game worn farve jersey.
Fcking thing was brand new.
