The Chip Rack (19th) identifies that blue HHR 10 cent "Gold Rush" as being "attributed" to Goldrush Wendover. I'm doubtful too, as it is clearly two words on the chip, and all the other Wendover, NV chips say "GOLDRUSH" one word.

There are other examples of this. For example, this Bonanza chip, which I'm pretty sure is a California chip, but The Chip Rack cautiously "attributes" it to the Bonanza in Las Vegas. It would not make sense for it to have been used in both places, and for Nevada to have used just one chip in the series.

The challenge I imagine for the Nevada administrators is that if one of them removes those chips from Nevada, a year or two later someone in good faith will ask for them to be added to the Nevada listings, because they are listed in The Chip Rack. It will be hard for an administrator (there are a couple for Nevada, I think) to remember not to relist it.
