from posts & a coupe of emails is as follows.....

* 2002 Chip was used (or given away as a souvenir) in Nevada and more precisely the Grand Sierra in Reno
* The $50 chip was apparently a 2nd rebuy chip, the first being the same chip with a $25 denomination (I have the same chips in 25 but it does not have a $ sign like the $50). At which event and at which casino in which state seems to be a mystery for these chips.
* The smaller inlay $25 I have no info on as yet.

Feel free to dispute or fill in the gaps. I would love to place these chips under a casino if at all possible. Thanks so far for those that have responded & emailed.

Cheers, Tim.
