Yes hang on to them. I have then entire 1990 Pro Set with Emmitt Smith's rookie, plus many others. And a Roger Staubach (don't remember the year 197?). I used to work for Roger, and I got the AWESOME chance to talk shop, pose for pics, and after shaking life a leaf and gushing all over him, he put his Hall Of Fame Ring on my hand. His hands and fingers are HUGE! I was in heaven.
As for the tools and their stupid remarks.....are you supprised, coming from my350z.com? It's sad how much nastiness and negativity are on this forum.
