I just bought a black light...I am having some fun with the chips in my collection.... Can any one tell me what all the Luxor $1 chips say.. I have one with the UV mark "NILE" the othe is blank... Barbary coast chips "98", "99", "01" are these year mint marks? Does any one collect chips for the UV tags or Am I the only one thinking about having alot of chips that apear to be the same but are UV taged different...I also Made a find that I am pleased with, a first issue Harrah's Marina AC black ring with NO UV Tag... I have been getting several of these chips and the all had the purple UV tag...But one... Any info would be great on the LUXOR and Barbary Coast chips...PS. If you have not looked at your chips with a Black light do so, You will full in love with the chip collecting hobby again.....
