Does anyone out there how many Las Vegas and/or Nevada Casinos issued a $5 LE chip in 1997 for the USAF 50th Anniversary? I already have these chips from the following casinos:

Bally's
Barcelona
Fiesta
Imperial Palace
Las Vegas Hilton
Sahara

Are there a bunch more of which I'm unaware? Short of having to pore over the latest edition of TCR, I'm not sure how else to find the answer besides asking for your help here. Any info provided would be greatly appreciated!

Thanks!
