A fellow I know in the coin club I belong to said he had some miniature insulators and asked if I could find out about them because he is not an insulator collector. This morning he handed me the box with his miniatures inside. It was a pleasant surprise to see a clear and an amber CD 216 Armstrong / Whitall Tatum salesmen sample. I think he will be a little surprised when I tell him the value that is listed in the Briel Price Guide.
