Here is a link to an interesting thread over on ChapTalk.net. Being discussed (actually, being offered For Sale) are three of the five colors of Sahara NCV's.

Total available quantity is about 3000 chips. Also noted in the thread are the existence of the yellow and black versions, with numbers indicating 300 yellows and 11 blacks, but only the other three colors are For Sale at 90 cents each, minimum buy is 100 chips.

I expect that these quantities will affect the TCR values for these chips.
