This explains the No AC on everything except the Harrah's. Harrah's certainly has gaming establishments in other jurisdictions.
I guess that Trump (TAJ) chips did not need AC or NJ since Trump did not, at the time of issue, have casinos in other jurisdictions.
The Plaza chips that are on the tables now would seem to be in violation of the regulations unless these are truly old back-up chips which at the time of manufacture did not require AC or NJ because of the same reason as the Taj chips, OR the CCC granted an exception OR the CCC simply missed the boat. Take your pick, or supply pertinent information if you have it.
