... I do not know, but if I had to guess; I would think the item was imitating an actual casino name (not a fantasy casino), it's facade (an actual artist's rendering of the building in which the named casino existed); the dates of operation (actual dates of operation)... and depicted on an item which is a reasonable facsimile of an actual casino chip.

More accurately [IMO]; the item is a commemorative of an actual operation...
