This is one of many that were in Colorado silver strike machines. Only a few casinos there could afford the costs for the dies to be made. So the casinos went together and paid for the dies.

Some the same and I have been told lets say 4 casinos had this design while another casino had a different design. That way a collector had to go to each casino to play if they wanted a set. Lots of them out there but slowly they are all going to the melting pots with silver up in value.

By the way, there are 6 in the set.
