The value of a coin collection depends on the care taken to protect the coins. The care of a coin collection can be as simple as putting the coins in a box and stashing them away but as the collection grows the collector needs to move up to more sophisticated protective methods.
One way to protect a coin collection is with a dedicated binder with plastic pages. Using this type of album will protect the coins from finger marks, scratches and other damage. In addition it will help to keep the coins safe from environmental damage such as air quality. Air pollutants like smog and cigarette smoke can react with the metal in coins to cause corrosion. This can be prevented by using a plastic page holder that is made from inert materials.
Another option is to use a coin and currency holder album. These albums have a high-quality PU leather cover and a clear plastic sheet on the inside that protects the coins. These albums will keep the coins organized and they will also allow you to view both sides of the coin.
There are also other types of coin storage that will fit in three-ring binders available at local office supply stores. These are a little more costly but they will protect the coins from damage and make it easy to catalog and locate coins. Other options include coin flips, which are small, plastic dual-pocket holders that will hold a single coin. These can be used with paper inserts that describe and catalog the coin. These are popular with coin dealers but can be a little difficult to open because of the staples that must be inserted.
