Boy, you guys must go crazy over the colors of these things sometimes. In the 10th edition Chip Rack (p. 77) there is only one chip like the one of mine pictured below -- (N4070).

But in the Campiglia-Wells price guide (3rd edition, p. 53) there is:
¶ an 8th issue one with 3 white and 3 purple edge spots, worth $10,000 new; and
¶ a 10th issue one with 3 purple and 3 beige edge spots, worth $6000 new.

Which do I have? On the real-life chip, the purple is darker, but that is not the issue here. The other color is a little off-white (due to soilage/use/wear?), or is it beige, or is there just one chip?
