Hi Don; Thanks for the info and for providing a link to your site page. I note that all the Colorado tokens you list have either a "locomotive" or "logo" description of the other side. Mine all have a horse and dismounted rider with a rifle at his side and no mintmarks. Did receive an email from another chipper, Dennis, who also felt these generic tokens were from Colorado.... and maybe even from some boats that also use them. Seems to me that a casino would want their own name on any tokens they are cashing so that they are not honoring silver strikes won at other properties. Anyhow, thanks again for the quick response.
