The chips for sale are known chips. Below is a screen scan from my website. This will eliminate many potential bidders.

BTW, note the following picture from the auction:

It appears from the picture that the winner of the auction will be getting a full rack (200 chips) However, in the description it is pointed out there is only 168 chips. Obviously fillers have been added to make it look like you will be receiving a complete rack of chips. I think its a cheap trick to help boost the final price of the auction.
