I have two small Boy Scout pins in gold tone metal. Both have safety C-clasps. The pins are very small, measuring 11/16 inches long for the larger pin and the smaller measuring 1/2 inch in length. Neither of the pins is marked with any metal content or patent dates. The small pin is a fleur de lis and the larger pin is the same fleur de lis with Be Prepared on a banner beneath the fleur de lis.
Both of the clasps work well and close securely.
