Shameless plug I listed a few older AZ chips on Ebay.
Included are some harder to get AZ chips like the old Desert Diamond fractionals (one satin, one linen) and the Dark Center $5 chip.
Also, there is a beautiful $5 Desert Diamond Millenium chip. Scan doesn't do it justice at all.

I do not have extras of these so if you collect AZ or Indian Casinos, these would make nice additions.
Thanks for looking.
