I can't believed someone paid $1000 for that.

CPU collectors pay serious money for pre-production or rare CPUs. There are some bizarre and highly sought after parts, two I can think of are OEM only releases of Socket 478 Pentium 4s which support EM64T (no normal 478 Pentium 4 had 64 bit support.)

Or another weird one:

Speculated it was sold to major stock traders.

I have a couple of engineering samples that I stumbled upon strangely enough. One was an engineering sample of a 2.666 GHz S478 Pentium 4 in a computer from a second hand store. The other is an EFX68000C16 from 1979 (an engineering sample of an MC68000 rated for 16 MHz.) It came from an estate sale of an old Motorola engineer. The first worked until I accidentally broke a pin and the second is unstable in a Sega Genesis console I installed it in at any speed.

I understand that, but none of those were particularly rare.
