I made a trip to Fallon and Winnemucca last weekend, and I now have the following chips available:

Headquarters Bar and Casino, Fallon
$1 chip is $3 each, $5 chip is $8 each, $25 chip is $30 each. (They did not make a $100 chip.)

Winners Hotel and Casino, Winnemucca
This chip was actually released last May, for the 10th Annual Run-A-Mucca Motorcycle Rally. They are $8 each.
