Ed - sounds like fun and a good idea.

When you get ready to start compiling your data and chips to do this... get a hold of me. The Harrah's chips have MANY interesting UV marks and changes. I can loan you or send you anything you don't have to assemble the display... like "HET HET HET" across the inlays (for HARRAH'S ENTERTAINMENT) or just "Harrah's" in tiny letters over and over on others.

AND I use UV lights to distinguish been the different minor .... dare I say it? COLOR variarions on the $2.50 Coin Inlays. And (are you looking Archie ) there are 3 distinct UV differences in the Harrah's $1 gray rings and black rings. Some of these have been recognized by font differences, but under UV light... each chip looks VERY different
