There are 5 or 6 different wooden tokens from the Sands in Reno, Dave. All are listed in the Nevada Promo Token book. There's also this aluminum free-play token that usually sells for about $5.

In addition to the $25 Sands chip that was shown on the board, there is a $5 which has been around for quite a while. I believe L.C. Meredith in Reno still has them for sale.
