There is at present an auction featuring a $25 reverse image millennium chip on E-bay, Auction #403878575. It is listed as an error chip.
A similar chip sold on E-bay within the last week for $144.25
Unless I am mistaken this chip was issued as such on purpose. I believe it was discussed on the board before. I have E-mailed the seller.... Am I nuts? About the chip I mean. [John I know you were waiting to jump on this one]
