I have just acquired a mass quantity of Chipcos. Most of this stuff is one each, no duplicates. A very few are two each. Here is a group of 19 notched sample chips that are available for sale, first come first served (please email offers). These chips all have the Chipco logo on the reverse. The image in the bottom right corner is representative of the logo. Some have a white background instead of yellow, some have text in a semicircle around a larger pile of chips. I'm asking $8 each, plus 50¢ per package shipping. I will entertain trades for Northern Nevada chips I need.
