These I know very well, have a very large collection of AC chips, all types and memorabilia. So, know those well.

The L. Green AC (quite a rare color) you also see there were the first roulette/poker chips ordered in 1928 While the casino was only partially opened, there were 8 colors of these. Then in 1929, with the casino much larger and with many more tables, the simple AC chips, of which a very small number were ordered, were replaced by the AC with table numbers. Of these, large numbers were made, therefore easier to find nowadays.

But, your info of what happened to the chips after AC closed, is quite interesting!! Thanks for the info!
