Since there has been has some talk about Win Chips lately, I dug mine out, as well as a few other ncv's. The Four Queens chip is an old one that has been replaced with a new design. the Sahara and old Santa Fe ncv chips were obtained through a coupon program connected to the Las Vegas Advisor publication. The Sahara deal has $50 (10 $5 ncv"s) available with the coupon for $40. The Santa Fe program was similar, but it was $20 for $10. The only extra chips I have left are some of the Circus Circus ones, if anyone would like to trade. I have the Aladdin win chip coming to me in the mail, but any others I would like to add to my collection.
