This Air Force Money Clip has been a very big hit for our customers with ties to the US Air Force. The Air Force Challenge Coin we mount is made of Military Brass and is Handsome as it is rugged. It features the Air Force Emblem as its design. The Challenge Coin is the size of an older United States One Dollar so is perfect for a Money Clip. The Money Clips are of very high quality and are finished in a Beautiful 14 Karat Gold Plating.
