I have a $100 chip from Sahara Tahoe encased in a clear plastic cube. This cube has all four corners shaved off. It was given to high rollers in a tournament probably between 1978 and 1982. It is a black with green chip. Has anyone seen another like it, have any idea on it's value, or may be interested in purchasing it? I'm more curious than anything. I have been carrying it around with me since 1982. It was given to me by the head of P.R. & advertising of Sahara Tahoe at the time.
