Stainless steel spring-tensioning money clip (frame only). Insert your favorite half dollar, including the Walking Liberty, Ben Franklin, JFK and Commemorative half dollars or 30.5mm diameter medallion. The Money clip's channel is closed with a jeweler's screw, which is packaged dipped in Loc-tite in a small poly bag. A shim is supplied in case your coin or medallion is slightly smaller than the diameter capacity to keep the coin from spinning. A jeweler's or small screwdriver will be needed and clean work area not to lose the screw if dropped. Feel free to contact us if you have any assembly questions.
