I found it on the list..

National Pastime Buyback Game Used J.Gonz 01 EX Wall 3 N/A N/A
I'm not familiar with the pasttime product, do these cards have some sort of stamp on the back?
Here is a Nomar card from this product and I don't see anything on it to signify it other than the handwritten number.
