Military challenge coin display cases can be found online at shops that specialize in selling military collectibles and at retailers such as Amazon, and Medals of America, or at hobby and craft stores. Typically, military coin cases are made of a hardwood such as walnut. Large display cases have four to six shelves that hold over 40 coins.
Military challenge coin cases are designed as a wall display or desktop unit. A wall display case usually has a clear acrylic cover that latches shut with magnetic or brass closures. Covers may also provide coins with UV protection from outside light. A desktop case displays coins in the open without cover. Some cases include a felt background to cushion coins.
