decide what specialty you like - by state, topic (say, chips issued for holidays, etc.) - maker of chip (T. R. King Large Crowns were mentioned). Now go to eBay and see what people are asking for them. Know that there are thousands of chips out there, some are rare and will command high prices, but many are not particularly scarce, and are reasonably priced. Or you can check on this very website, as offers of chips are posted on the ChipBoard almost every day. Hope all this helps out!
