AA Medallion Holder Keychain For Use With BSP Bi-Plate Coins and RecoveryChip Gold Plated Medallions. The holder opens with a VERY VERY small screw at the top. This is a very secure precision design. The downside is that you must have an extremely small flat blade screwdriver to open the hoop and then insert your medallion. I used a screwdriver from a computer repair kit but maybe a jewelry or eyeglasses repair kit might work. Note: This model is not for Wendells or Tri-Plate BSP medallions. We have other product listings for those.
