Hey everyone, have a question about this Ted Williams signature at a local shop that comes with his COA (Green Diamond) as well as a Steiner sticker. The COA has John Henry Williams as President of Green Diamond.

Question is, is there any concern with Ted's signature with Green Diamond certs with JH as Pres? I've heard JH had Ted sign tons of things before he died. I've also heard that JH may have signed for Ted, too. 

This shop has JSA come in monthly and the vast majority of stuff in the store has a JSA cert, but this one does not. Am I just being too paranoid? Should I be pretty confident with Green Diamond certs?

Thanks listening and the help you all provide!
