I know a few of the older casinos do have those unique or only 2 or 3 known chips. I'm really not worried about those, if the time comes where I can obtain one of those, even better, but that wont totally discourage me. I know there will be a couple "big money" chips almost no matter what. Anyone have any idea where I can get a complete list. Say I choose MGM Grand, how many chips would I be looking at? I am already getting new releases on current casinos, so those I will always have, I want a challenge.
