I trade a few high value for lots of low value and vice versa all the time. The way I see it, if you're willing to give me what I view as about $35-40 worth of cards I want, you can take whatever $35-40 worth of cards from me. I've never had a problem with it, which may be why I've always listed all my commons.
I appreciate Chicago players that begin competing within the city's sports organizations and stay with these teams throughout their careers.
