I will leave the law to Jim, sounds like he knows it. I do not want to open the same can of worms again.
It is possible we are dealing with Casino Policy instead of the law. In Nevada, Casino Security is the law. The police have no juristriction unless they are invited.(unless they chase someone into the casino). Sort of like State Police entering the city limits. Some security guards are pretty hard nose. It does not matter what we think the law is, it is what they think. Is anyone willing to fight a court battle for being trespassed warned over a roulette chip?
As I said before, I have no problem with you collecting roulettes.

My little story was meant to say that some of the posts went a little too far. The hobby is fragile. Why should one collector care what another collects. We are all adults and if a roulette collector gets in trouble, let him get out of trouble his own way. I think there are bigger battles to fight than yes or no on roulettes. Like this fraud thing.
