Katie, of course Greg and Robert are right on the promo Casino chip.
Here is the chip used on the tables in the movie Casino.
I have the set $1, $5, $25, $100, & $500. The $1 is the best scan.
Tangiers was the name of the casino in Casino.
The closed Sport Of Kings in LV was given a new facelift with signs, paint, etc for the set of Tangiers.
