Hello,

I am very, very new to autograph authentication.  I am just starting to build my collection in which I will be collecting a number of basketball jerseys.  I am doing a lot of research but would like to hear the thoughts of the experts in this forum.

A couple questions below

• PSA vs JSA vs Beckett vs Upper Deck vs Pannai - For PSA you can enter the code and they will tell you its authentic but what about the rest of them?  If they are not like 99% correct, how do you confirm that they would be?
• Does pricing vary based on the authentication service?  Like is it worth more if PSA authenticates it vs someone else?
• What other things should I look for when purchasing signed jerseys?

Any other advice would be greatly appreciated.
