I don't see a casino name, Jesse, only the name of the company that had the bar made. There were so many commercial bars made in the 1970's and 80's that I doubt any are scarce or worth a premium. What is rare and valuable are bars from the 1800's, either from private mints or from the US Mint itself. I auctioned one for over $800 a few years ago. It weighed about 4 ounces.
