I was there for derby day. I was down with at least 20 friends from school. WE all got one. 2000 was the first year that I was aware that there is a chip collecting hobby that is organized. In June (after seeing the listed value)I contacted all my friends to see if they still had there's. All of them had thrown there's away. I still have mine.
As I remember they went very quickly. I believe that the staff there had kept quite a few for themselves.
Thanks for the info Gene!
