First question is what are you selling? If you have high end stuff use an auction house. For baseball its tricky. Grey Flannel is the go to auction for basketball and football but I don't know how their baseball stuff does. Lelands seems to always have a good baseball selection. Most charge you between 15 and 20% depending on a variety of factors. For the cheaper stuff use Ebay or the classifieds here. I agree that individually is better. Alot of collector's don't collect a team but collect players and that way they will bid on your stuff. If you sell the whole thing as one lot it will discourage bidders. Personally I collect NFL stuff but only one jersey per player no specific team. If a jersey I wanted was bundled with alot of stuff i didn't want I wouldn't bid unless it was something impossible to find that I had to have. Also you might want to talk to Barry Meisel he sold Rangers stuff for awhile a few years ago maube he would sell it on consignment for you.
