The dates you cite for the Reno Hilton don't make sense to me. I see those dates on the Chip Guide, but the Wikipedia entry for the Grand Sierra Resort (the current name of the casino) shows dates of 1992 to 2006. These dates seem more likely to me, since I went to the Reno Hilton. I even got this deck of cards directly from them at that time:

I was there at least twice, but the only times I have been in Reno were between 1992 and 1997.

I think the dates on the Chip Guide need to be checked.
