Hi Dennis,
Those were basically put out by the "Founders" of the Sturgis Rally's.
Some were given out by the people who run Sturgis, and were also
sold in some of the shops. From what I could find out, they were not
gotten out of machines in casinos even though some are .999 silver.
Some I have say issued by the "Founders" ....
I have some somewhere, and will look for those when we get home.
Mary & I are currently in Las Vegas until Dec. 18th.
