I collect $2 gaming tokens from Nevada.... another odd denomination, kind of like the $2.50 chip in table games. There don't seem to be too many, but I've been able to find 37 different which you can see if you click the link below (large 330K scan).

Most are for playing $2 denomination slot and video poker machines, but some of the Harrahs and Aladdin are "premium tokens", paid out by low-roller slots. Not shown are the older large-size $2 tokens from the 1960's that were primarily used at the $2 blackjack tables.

I have extras of a few of these and would be glad to trade for any not in the collection, or will sell. I found Riviera, Stardust, and Green Valley Ranch last week in Las Vegas, although almost without exception, the machines were set-up for paper-in and the tokens will likely be retired shortly.
