I echo Jim Steffner's post includeing the Gamblers General Store http://www.ggss.com where you'll find Bill Akeman's Chip Gallery. Also Gamblers Book Club store, I got a good price on Campiglia and Wells' guide there. Search through any in-room magazines and get a free pass to Tropicana's Legends Hall of Fame museum. You'll see hundreds of rare (really!) and scarce chips. Their gift shop has a lot of chips for sale at Y (Yikes!) prices.
