I got this pair of Colorado Hotel tokens on eBay last week. Janice's list only shows one metal, but doesn't describe its color. Dan Wickett's site shows only the silver-colored one. Does anyone know which is the circulation strike, and whether the other is a prototype struck on a different metal? I guess the one on the left could have been plated; it appears to have no wear at all.

You are welcome to the scans if you need them, Dan.
