They are said to be from Las Vegas.
The seller lives in Las Vegas and I have
no reason to doubt him.
I know there were several Northern Club's
in Nevada back in the 30's and 40's.
I don't know of any in Tonapah, but The Gaming
Table lists one in Goldfield, opened around 1910.

I see you show a couple of Bank Club chips.
Here is a scan of a pair of dice.
I got these with a group of dice from Las Vegas,
but I can't attribute these to Las Vegas, yet.
They are rather old, and all the dice that
came with them were from the 40's and 50's, so
there is a chance they could be from las Vegas.
But the seller of the Bank Club dice didn't know
anything about dice. And was not living in Nevada
even.
