Don't forget that there are 3 or 4 different $1.00 in play. So you go to the poker room (for example) buy a rack of chips and you'll get a number of different types of chips. Take a look at http://www.silver-state-treasures.com/lasvegs/silvrton.htm to see them.

Maybe one of the new issue services or a local can help you. But the Silverton is a great place to go. I always enjoy my time there.
