The answer I was looking for is the Golden Nugget $1 and $5 chips, TCR#'s N8463 and N8468. These chips were issued by the Golden Nugget in Atlantic City. The chips do not have a location identified on them, just the casino name and denomination. They are also very similar in style to chips used in the Golden Nugget in LV. The unconfirmed rumor is that these chips began showing up at the cage in LV and were accepted there. That is why they are in the TCR. One of the TCR authors told me that these chips may be removed from future editions, unless the rumors can be substantiated.

It appears that Barry Hauptman was the first to post a partially correct answer, but he transposed the digits on the TCR# so he is not 100% correct. Travis Lewin also had a correct answer, but his post is 51 minutes later than Barry's. Since, I cannot tell who is the winner, I'll name both Barry and Travis as the winners and they will each get a $1 chip. Send me an email with your mailing address. Congratulations.
