I think that you will find selling all of those guns at a gun show frustrating. Unless you price them where dealers would consider buying them, they would be slow movers because you'd have to match them up with the right collectors. I would suggest contacting Rock Island Auction. http://rockislandauction.com/
These guys run a top-notch, honest auction specializing in firearms of all kinds. I've attended several of these auctions in person and am always impressed. What I'd do is contact them and see if you can send them your list and then get their feedback.
