Dennis,
Laughlin, NV has a slot machine that you can win silver dollar coins from. If I remember right the slot machine is at the Riverside Casino in Laughlin. We went there last November. About the same time as the Palms Show. If it is still there watch out it's a very hungry slot machine. At least for the one's who played it then.

Don't remember which casino in downtown Reno. Has a silver dollar slot machine. But when you crossed the alley from another casino. It was just inside the alley door. I have not been to Reno in quite a while so I cannot veryfiy it's still there.

Don't be surprised if you get at least some of or all of the earlier CLAD SANWICH TYPE silver dollars. And that they are pretty beat up. Seems I remember that what was gotten out of the Laughlin machine. I actually did not play the machine my self. But I saw what the others ended up with.
