Yes it is! Very historic, very cool, but no sir, for the 3rd time, i do not want to buy it for 20K!
I have no chip in my collection that I value that high, don't want to own one that expensive and think with a box around every corner veiled in secrecy that "investing" in a chip that heavy is a fools errand.
I respect the offer, I'm the wrong guy as mentioned.
PS: You've been trying to sell me this chip for 3 years now and you still have it. That says something. Tell you what, I'll give you double face value for it, yep $10 for a $5 chip.
