The Nature Boy said:well if you want to sell them all at once on EBAY go for it. Take some pics of the good cards to prove you have them and say you're selling your whole massive (use cool adjectives) collection, which includes Bonds, Sosa, Ripken, etc. You're more likely to encounter people who will pay more on EBAy than some dude at a baseball card shop that has been in the business for a long time. Worst case scenario you can set up a minimum amount on your collection so you don't get stuck selling it to some clown for $40.
Probably gonna go this way.
Thanks bromeslice.
