An extremely fine set of First World War U.S. Marine Corps collar disks that are in excellent condition. Each disk retains virtually all the original dark bronze finish and is complete with fully functional, unbent screw posts, and circular nuts. The stabilizing pins on both disks are bent due, no doubt, to the thick and impenetrable wool of the uniform collar. Each disk is with fine detail and background stippling. A seldom encountered pair that remain in excellent condition.
