Anyone know the story on these? I believe Armin told me they were made by a promoter who contacted each casino and then produced a design for each. I don't know how many casinos there were, though. I have a note on one of them indicating a mintage of 500. These are all .999 silver and some have some really nice toning after 30+ years. Edges are plain except for identifying legends and "Made in Canada"... Royal Canadian Mint, maybe? Diameter is 39 mm.

I have an extra Sahara available for $75.
