Staple-type cardboard coin holders and coin flips need to be stapled to insure that the coin stays in the holder. A traditional stapler will leave the backs of the staples sticking out slightly. The staples can then come into contact with other coins in your collection, or the holders they are in, resulting in scratches and other damage. Max staplers bend the backs of the staples flat so they will not scratch or rub against other coins or coin holders and they stack neat and flat for easy coin storage. These staplers are for both staple-type cardboard holders and coin flips.
