Someone had these at the Minden show last week, Mike. I'd never seen it before and didn't get one myself. It certainly seems to have American Revolution symbolism, with the eagle and snake on one side and the liberty cap on the other. Hope someone with knowledge of these responds.

Now that I think a bit more, isn't the eagle and snake on some Mexican coins? And is that a cactus the bird is perched on? Maybe they could be from south of the border.
