Response from Manie, seller of these chips:

Hi John: I can only tell you what I was told. Jan. 2001 the Gold Dust West closed escrow to Black Hawk Gaming { they used to be the Gold Dust Reno ]At that time I was told they destroyed all gaming chips. I do wood working and they contacted me to make them some desk chip holders. They told me that they held back 100 of each for that purpose. In exchange for the work they gave me 10 of each. all of these chip holders had the chips epoxies in . I just decided to sell mine because I need the money that's why I'm selling them so cheap. I hope this explains mine. I don't know about the others. Thanks MS

I don't know if his story is creditable. I DID NOT purchase them. I think that $200 for the set is about right though.
