When the Luxor first opened with Chipco made $1 chips, they were UV tagged in one of 6 versions (TUT, PYRAMID, LUXOR, EGYPT, NILE and CIRCUS CIRCUS) and no tagging. This tagging was done by Chipco and not by Luxor, as an experiment to test UV tagging (this according to the Chipco at a presentation given at one of the Club Educational Seminars some years back at the Tropicana).

After a period of time, they stopped tagging the chips all together. More recently, the Luxor (now an MGM/Mirgae property, not Mandalay Resorts (Circus Circus, Ent.)) is using GPI (Paul-Son) made, lead-free chips with the standard top-hat and cane (Paul-Son logo) UV tagged in the center of the chip.

So, yes, you will find a UV tag on current Luxor $1 chips (and all other denominations) but not on all older (Chipco) $1 Luxor chips. But the coolest UV tagging was on the 6 different, earlier releases of Luxor $1 chips from Chipco.
