There have been many threads about casino chips being poured in concrete thru the years here in the USA and off shore... and even photos published in our club magazine.

One interesting story about obsolete chips being destroyed was from a French casino; whene the inventory was turned over to a sculptor who created a three-dmentional representation that was erected in the town's square made with the melted chips... Perhaps they should try that in Vegas; see how high they can make a "Tower of Chips."
