You've got the right idea about casino chips. Some casinos have chips they only use in their poker rooms and tournaments so I was curious if that is what you meant. As your collection grows you may specialise in different kinds of chips and some folks collect poker chips. There have been plenty of different examples of private/casino/home poker chips over the years and you can have a pretty large collection just of these. Plenty of casino chips to collect and many $1 collectors! You can pick up a lot of info here on the board by reading or asking questions and the price guides have good intros in them. The hobby is pretty easy to participate in and there are lots of ways to enjoy it.
