I got this at a chip show sometime in the last year but am just getting around to adding it to the collection. I don't see it in either chip reference but it's one of many chips apparently used in Pan tournaments at the Plaza. There are also purple ($1) and orange ($5) chips with the same blue "No Cash Value Las Vegas NV" overstamp.

I cannot make out the original denomination under the blue stamp but it looks like $80.00. Could there have really been an $80 chip? I know they have a 70c chip, but $80 is really strange.

Color is closest to Paul-son Chocolate Brown.
