I had picked up a graded Ted Williams baseball a while back, and kept it stored for a while.  I noticed recently that from the movement that the ball has moved around and the signature isn't showing.  I'm not a fan of the whole authentication/sticker nonsense, but would cutting the seals that are keeping the baseball cube close null and void the grade of the ball?  I only care because if I or someone else has to sell it in the future, I don't want them to be accused of tampering with the ball or for switching it by having cut the seals.    

This isn't the ball I own, but here's an image of the seals so I can clarify what I am talking about:

I appreciate the help!
