I bid on this trinket in error at the auction last week as I have one. 1921 Morgan Dollar with bezel marked with the original Harrahs Club logo used when the Tahoe location opened, probably in the 50's. The bezel isn't marked but appears to be silver as well from the toning. These don't seem to be listed in the Nevada Token catalog.

You can have this one for the sale price, less commission, and less shipping: $40, delivered.
