Hiya JnC welcome to the board and chip collecting! Do you intend to collect casino chips as well as Las Vegas poker chips? One source of sales websites are the banner ads you'll notice here on TheChipBoard. The folks that run these sites usually post here as well. Just start clicking on the banners and start shopping! As for a value guide, collectors usally pick up The Chip Rack by Knapp, Myers & Wheelden first and suppliment themselves with Campiglia/Wells The Official U.S. Casino Chip Price Guide. Either and both are good investments in the enjoyment of the hobby.
