I have found other CC chips back East with the same hot stamp and sm-key mold from a different source than these. What is interesting about the ebay lots you are questioning is the orange "Colony Club" chip. I remember Howard Herz selling a few sets of the Colony Club and Colony Casino, Reno chips in the $5, $25, & $100 denoms many years ago along with the same orange "Colony Club" chip as is shown in the ebay lots. Because of this, I have assumed that these are from Reno, but just have identical hot stamps and molds to others issued for other clubs.

Hey, my 1st post! Hope it was helpful!
