I have some of the new variety of $1 chips from Harrah's, Joliet. This version has a lighter color print versus the one prior to it. Not sure how many people like different varieties but I have several for trade, if interested.
This is the new chip CG19129

Here is a comparison with the prior version that is still on the tables but very well used. You can see the one on the left is lighter (these are the ones I have to trade-CG19129) and the one the right is darker. Under a magnifier it looks like the one on the right is black and the one on the left is light purple. Greg explains it a bit different. Looks like they came out in January sometime. The chips I have are in excellent condition. http://www.chipguide.com/cgi-bin/search/search.cgi?id=iljoha

E-mail me if you wish to trade. I have a few of them.
