I have one set of the chips. They are Ewing mold therefore made pre 1960. Some wear on the yellow $5 and the $25. The red $5 looks new to me.
$25 including postage.
I also have 2 extra red $5's.
$7 including postage.

I don't know anything about the casino except I also have some BJ coin Inlays chips from there. These would predate the coin inlays.

Email me if interested.
