Michael,

I really don't know. I asked the other members of this message board, and all I could find out is that they are scarce, and they were not specifically put out by the casinos themselves.

The best I can guess is that they are some sort of commemorative silver coins, minted for collecting.

If you find out anything else, please let me know.

Thanks.
