Hey Paul,

The only LUXOR $1 chip that I have where the side a and side b UV markings don't match is the Luxor/Circus Circus - which is already on your list.

I'm also working on a set of these chips and was wondering if anyone have and dups of these or any other mismatch UV markings:
Egypt/Blank
Pyramid/Nile
Nile/Luxor???
