【U.S. Military Surplus】 ※ This is a challenge coin from the U.S. Department of Defense. Made in 2018. Commemorative coins awarded to members of the Army, Navy, Air Force, and Marine Corps who participated in missions and exercises and achieved excellent results or were outstanding personnel. ※ This is a challenge coin from the Federal Aviation Administration (FAA). Each one is not for sale, and I think it's a rare item with a unique design. For those interested in the U.S. military, military items, etc., and collectors, please consider this.
