I have seen this topic before, and sometimes a heated discussion, so my question is: Is there a way to find out, without directly contacting the casino itself, if a chip can be cashed in or not. Is there a Casino Commission in Nevada that dictates how long a casino must honor a chip, or is it up to the casino itself. I am sure one of the more learnered members will be able to shed some light on this. Thank you all again for helping me learn my hobby. You guys are the bestest.
