Ok I purchased a 2000 Leaf Certified Materials Certified Gridiron Gear GU card of Edgerrin James from eBay. I received the card today and it is warped along the bottom, very bad. It looks like the ocean, there are 3 valleys and 2 peaks. There are no liquid stains on the card and no creases or anything. I took the card out of the case and it is not something that was caused by the case or can be fixed. Now my questions are, how thick are these cards? Does anyone own one that can scan the back and show me the serial numbering? My #'ering is very bold and does not look like the #ering on my other 2000 LCM GU cards. I also pulled the card out of the case and swear this card is no thicker than a base card which I find VERY odd since its a GU. So someone that owns one of these cards (can be of any player not just an Edge) can you please let me know what the numbering looks like and how thick is this card? The seller has said she will issue a refund, of course I am out shipping ($3) and I need to send it back so there goes another $1 or so, grrrrrr.
