My collection is a mess...I have far too many cards to deal with! I wish I could help you collect a few, and maybe make a few $$$ (or trades), but the truth is I'm so unorganized I wouldn't know where to start!
THAT said, other people here are far more organized and should be able to sell/trade with you easily. What would help is for you to specify terms a bit more. Are there specific teams, years or types of football cards you're interested in? Let people know and they'll likely jump on it.
Which reminds me, I still have to find my Cowboy's cards for a potential trade...it's been months since I said I'd find the time, and with my boss leaving town for a couple of months, I better get on it while I can lol
