Does it matter if the cards have been signed ?
Just listed several signed cards on ebay. If your interested. I also have others.
I have signed & framed jumpers. I have signed balls. You name it, I'd be pretty certain that I have it. Weather or not I have 1 spare is another question. I do have doubles of some cards.
If you take the time to look at the ones I have listed on ebay, you can see that I'm not trying to get rich. All of my card auctions start @ .99c regardless of who or what it is.
