if it's from a shop of some sort, get the reciept. get it graded. if it comes out authentic then whatever the grade is, thats the grade. a 4 should bring you close to what you have invested into it. if it comes back as a miscut, trimmed, etc, as Jim was saying, bring it straight back to the shop you got it from. i'm hoping that within a year I can find an Aaron rookie myself. I've done some homework on it and it's a bit harder to find than a Kaline or a Banks rookie (both of which I have)...from my understanding, stars are graded a bit tougher, so if you think it's a 6, it may come back a 5. but still, a good investment...you can always figure out a way to trade up. good luck! I'd love to hear that you scored a 7, keep us posted!
