collect Colorado chips. According to the Colorado Chip Exchange (you can find them from a link from the main page on this site) there are only 3 sets of these chips known. The black chip is the tough one. I think with only 3 sets known that would put this set into the scarce catagory. I am calling these chip slightly used but many would call them unused. I know I paid a good bit for them years ago. The Colorado Chip Exchange has them listed for $150 and I don't think they have any in stock, though I may be wrong on this. I will trade for equal value in $2.50 snappers in very nice condition or I will take cash offers until tomorrow at noon.
