I deal almost exclusively in "Snappers" world-wide. Nevada does not seem to have UV issues in its snappers. However, many US casinos in the Midwest put $2.50 chips in their racks; and then "re-order" which can only be differentiated by the UV.

In lists and future guides to these chips, many of us look at the UVs.

I want to thank-you for your thoughts and now realize why TCR does not use the UVs.
