By that logic, these two chips should be taken off the list. They say Millennium nowhere on the chip, not even on the edge. And even if you just had one of the other two, you can't prove what it says on the edge. The word's cut in half! If you don't have all 4 chips to stack, you don't know what you have. What morons the Cal Neva chip designers were, to think we'd buy this crap as an actual millennium commemorative chip. I mean, I can forgive them for thinking 2000 is the start of the new millennium, but this! Sheesh!!!
