I try to get about 5 to 7 chips at a time for each color. I have found that if I get more than that it takes forever to get rid of them. I would not plan on making your fortune selling roulettes on eBay. There is almost no cash market for current roulettes and even long obsolete ones can be hard to get rid of. Like any collectible, get what you like and if you get a few traders contact me and we will work out a trade.
