With the U.S. Mint redesigning so many coins (statehood quarters, Lincoln pennies, Lewis and Clark nickels), more people have become interested in coin collecting. Supplies for collectors are readily available from retailers, but they can be costly. Protecting and displaying your coin collection doesn't have to be expensive. With a few inexpensive supplies, you'll be able to custom make your own.
Cut the poster board and plastic sheets into 2-inch wide and 4-inch long strips and fold the pieces in half to form 2-by-2 inch squares. These squares will become your individual coin holders.
Center the coin you want to store in the center of the 2-by-2 inch square. Draw a circle around the coin on the square. Cut the circle out on both sides of the poster board square at the same time.
Open the poster board square and place a folded plastic square inside it. Then place the coin inside the cardboard and plastic so that it is centered over the cut hole.
Close your coin holder and staple the edge with one staple each on the open sides. Both sides of the coin should be visible through the circles you cut and the coin should be held in place in the opening by the plastic and staples. Label the coin holder.
Individual coin holders can be inserted into slide storage sheets, which can then be stored in a three-ring binder.
Personalize the binder with a cover. This method allows you to arrange your collection in any way you might want.
This method of making a coin holder does not protect against oxidation. If this is an issue with you, coin holders are available for sale that will seal the coin entirely.
