Amy, I wrote an article in the club magazine on Oversize Chips a few years ago. If you weren't a member at the time, and want a copy of it, just let me know.

Also, FYI, the "Authentic Products" division of Paulson manufacturers non-casino chips that are oversize -- typically 50mm diameter. There's an Arizona Diamondbacks chip, a series of 3 Nevada phonecard chips, and some other specialty chips that are oversize.
