There were two El Morocco's in Las Vegas (you have listed as Morocco). This one was El Morocco Casino, at 2975 Las Vegas Blvd., open from 1972-1983. (your $1 gray hotstamp chip & $25 green hotstamp are from this casino)
(The other was El Morocco Club, 1332 N. E Street, 1945-1955 & 1957-1958. I don't have a picture of that one...your $1 chip with a Zebra, purple EMC, and $5 yellow are from that club)

Here's an older Four Queens, in case you like it better
