If you’re just getting into coin collecting—congratulations! We’re excited to be on this journey with you. Coin collecting is an exciting hobby with a rich history. As a new coin collector, one of the most important things to learn is proper coin collection storage. Keep reading to learn the do’s and don’ts of storing a coin collection to preserve the value and worth of your coins.
How Should You Handle Your Coins?
When you think of coins, “delicate” may not be the first descriptor that comes to mind. But you’d be surprised at how easy it is to damage and devalue these small pieces of precious metal.
- Handle each coin one at a time. You don’t want them to come into contact with each other and cause any scratches or other damage.
- Always handle your coins by the edges, never by the face.
- Wash your hands before handling your coins. Dirt or oils from your hands can tarnish the coin’s surface.
- Don’t handle your coins over a hard or bare surface. Use caution when removing your coins from their case. Handle them over a towel or other soft surface to reduce any damage that could occur if you accidentally dropped them.
- Don’t clean your coins. As odd as it may sound, cleaning and polishing your coins can devalue them. Improper technique and harsh chemicals can strip or scratch the surface. It’s better for your coins to show their age with coloration.
How Should You Store Your Coins?
It may be tempting to keep your coins out of any packaging or protective cases to be more easily shown off and admired, but that’s not best for the longevity of your collection. Coins are easily damaged by contact with other coins, oils from your skin and fingerprints, air, and moisture.
- Keep your coins in holders. The original holders are best, but you can also purchase your own. Single coin holders are usually 2” x 2”, and there are a few different kinds. However, some are more expensive than others. Cardboard 2 x 2s are the least expensive. They come with two coin-sized windows covered by a thin, polyester film called Mylar.
- Flips are another option. They usually come with two plastic pouches and are the most flexible. Hard-plastic holders are the most expensive. These two-piece capsules come in both round and square shapes.
- Avoid damaging chemicals. Some cardboard and paper contain sulfur which causes discoloration. And some plastics are made with PVC (polyvinyl chloride), which can ruin coin surfaces and coat them in a sticky, green residue.
- Keep your coins cool and dry. Discoloration due to sharp changes in temperature and moisture is often irreversible. Even droplets from talking or breathing over your coins can leave spots that are difficult to remove. Hard-plastic holders are more airtight than flips. Some are even made with anti-corrosive materials to mitigate the effects of damaging gasses.
- Keep any documentation. If any of your coins come with a certificate of authenticity or an information card, keep them in a safe place just in case you need them for reference later.
- Protect your investment. Keep high-value coins and collections in a safe-deposit box or a safe at your home. You can also add them to your home insurance coverage for the full cost of replacement.
