"If a casino had a chip in the cage and would, by policy, sell you the chip, then it's NOT obsolete. Everything else IS obsolete." ... Jay Sands

Jay; I guess you have not read anything I've posted about A.C. casinos.

With very few exceptions, one can NOT purchase chips in A.C. from the cage as one can in Las Vegas. That's the difference. Your definition is flawed in my view by using a Las Vegas standard and applying it universally. I can accept your definition when applied to Las Vegs chips. It is unacceptable (for me and many other A.C. collectors to use) regarding A.C. chips.
