Part of the story is in the Archives here.

The chip is NOT real. It is a stickered chip, but was done as a joke by another chipper and posted here some 5 years or more ago (if memory serves me right). When asked to get one, he sent it to me, saying that it was 1 of 2 that he crafted as a joke. I do not recall who it was, but I have it documented in my collection as a homemade, stickered chip on a CHIPCO chip. (No, I have not pulled one of the stickers off to see the underlying chip, because the insert pattern is probably recognizable. (Anyone? Anyone? Anyone?)
