Can anyone tell me what happens to chips (entire racks) at Indian casinos when they are taken out of use A) because they have been replaced or B) because the table has been shut down? Some seem to pop up later, such as the CBC (Cahto bingo casino) chips, others, not. I do not believe they are required to be destroyed, as I understand is the case with Nevada casinos, but my inquiries have really been shined on. Thanks for any input.
