Four pin back badges from the heyday of Harolds Club in Reno. The black one is #1 and the purple one #4 (Jane and Jim Jackpot) in a series they did for collectors in the 80's. I think there are 23 different.

Yours for $3 each, or $10 for all four. Shipping is $2 for any number of pins.

It would be intereting to know if anyone has all the Collector series.
