Common Mistakes of Coin Storage

Whatever type of coin collector you are there are three common mistakes that will permanently damage or devalue your coins. You should be aware of these three things to preserve your precious collection as best as possible.

The first is everyone’s least favorite PVC: or polyvinyl chloride

This is a commonly used product made for many applications, one being coin storage. However, over time the PVC will coat and corrode your coins, turning them into a horrible green mess. If you store your coins in plastic holders or flips, make sure that you are NOT using holders that contain PVC or polyvinyl chloride.

The second is the easiest mistake for a novice to make: Finger Prints

Coins should always be handled by its rim and rim only. Our bodies put off many oils, that when in contact with a coin, can become acidic and will stain them, often resulting in permanent damage. There are dips and solutions that can remove fresh fingerprints, but if a fingerprint has been left to age the damage is almost always irreversible.

The third enemy: The Environment

You should always store your coins in a cool dry place with controlled humidity, temperature and moisture. Packets of silica gel can also help to absorb moisture if you live in a humid environment. Make sure your coins are never subjected to direct sunlight. A safe or bank safe are ideal as they are generally humidity/temperature controlled environments. Humidity can cause spotting, unattractive toning, or haze, which will adversely affect your coins. There are storage products marketed under the name "Intercept Shield" that are tested and believed to be safe for longer term storage of coins.
