and mine are all silver, so they were once gold huh?

Yes, let me do some looking. I've been through hundreds of these looking for the "best chip" and I don't really think I have a Gold $2.50. But I have some of the others that look like fresh. I normally don't care about grade beyond, Like New, Used, Worn or chopped liver.

Let me help. None are rare! I think they made the rounds at three casinos. I had a home play set of these, which was stolen.
