I have a good friend who had received a pair of practice skates of Johnny Bucyk and they are autographed. I myself don't care about an authentication of a product especially if I saw him sign my product but this friend of mine wants them authenticated. So, my question is where can I have him send these skates to be authenticated and the autograph as well? Is it also possible to have them tell if they were his practice skates? Thanks for any help guys
