Interesting article. Thanks for sharing.
Have you seen any of the newspaper twice weekly ads, as required by NGCB?

Previous redemption ads I've seen are usually for a casino that closed, so redemption is for everything, to be done at a nearby casino, or a common-ownership casino in the area.

In this case, there are specific Plaza chips involved in the "retiring" / redemption, but not others that still remain in use. So the more detailed wording about the affected chips would be interesting to read. Color pics of the chips in question would be even better, but the regs don't require that.
