Don, The chip You are showing is not as rare as some people would lead you to believe. There was racks of them delivered. Several racks were put on the tables. No one knows how many. Once they were discoverd, Caesars made every effort to retrieve them from the tables. Cage cashiers called chippers. I had a BJ dealer call me. He got 3 for me. No one at Caesars will say how many were destroyed or if they were destroyed.
Before everyone asks, I already traded 2 of the ones I got. I know a dealer that had a few of them. Will ask if anyone wants one. I have seen them advertised at about $100 but not for awhile.

I have not seen the other 2 errors you mentioned.
