plaques to find!

I've posted this previously. This scan is from the back cover of a Caesars Gaming Guide. The guide was a hardcover booklet, probably sold at the gift shop. I have recently visited a closed, Facebook Group, for former Caesars Palace employees. I received permission to post there, in pursuit of validating these plaques, and several former employees recall these plaques being used in a High-Limit area.

I do NOT know if smaller denominations also existed, and if so, were there jetons.
