This card would probably sell for $20 maybe $25 max on Ebay. The signature pen hasn't worked out the best. The signature isn't crisp which is what most collectors look for when buying IP autographs such as this. As it is now, you are probably looking at $12 max
Just out of curiosity, Do you know when this card was signed?
i kind of guessed it was a very early signature. I haven't seen this signature before. Im used to his later signature where the Andrew joins to the Johns and not much of the "ndrew" is visible. I was talking to Josh Hoffman today and he is another player that has changed his signature slightly in an attempt to become quicker at signing his autograph. I don't think the autograph is more valuable because it is older. I believe the quality of the signature is very important to its value though and I will stick to the original guess of around $12 - $15. You may get luck and get a bit more, it just depends on who sees it and how much they are willing to part with.
