Coin flips make quickly storing coins effortless, yet safe and secure because they are PVC free and archival safe. To use a coin flip just insert a coin and fold over, that's it. Flips are a collector favorite for many reasons, one being they are made with two individual pockets that are separated but still connected. In one pocket a collector can put in a coin or medallion, and in the other pocket they can put in coin information with the insert. Our Mylar coin holders come with inserts that allow collectors to put almost any coin information they desire, the inserts can also be used as a display card.
