This is an extremely important topic. To get started, review my “Introduction to Numismatics” presentation on our Resources page. This presentation makes reference to useful ANA publications, including a guide to numismatic estates.

According to the ANA, “It is best to store coins individually in containers designed to limit exposure to detrimental elements as much as possible. These supplies for long-term storage, such as acid-free envelopes or PVC-free mylar “flips,” are available for purchase through your local ANA member dealer. Paper money should be stored in PVC-free, mylar sleeves. A dry environment in a fairly constant temperature is important for long-term storage of your numismatic items. If you store your collection in a safe-deposit box [or in a safe], check on your collection every few months to make sure no problems are developing.

Organization is also important – most serious collectors specialize in certain items (such as certain types of coins) and try to keep their collection well-organized. Otherwise, you risk being an “accumulator” rather than a true collector! Good record-keeping is recommended.

Coin albums can be used to organize a collection of a certain type of coin, although there are many other methods including storage boxes. (See photo at top.) The inexpensive albums where you simply push each coin into a hole in the cardboard should only be used for low-value circulated coins. Even the better-quality albums like in the photo should be used carefully. They have plastic slides which protect the coins but could cause small scratches on the coins if used carelessly.

Have lots of coins of the same type (Lincoln cents are a good example)? Then storage in rolls (or plastic tubes) can be a good choice. Since coins have raised rims, they usually stack well in rolls without scratching or “bag marks” but caution is nonetheless advised. If you’ve found coins in rolls which might grade MS-65 or better, then storage in separate holders is advisable, and you’ll need to do that anyway if you plan to submit the coins for grading.

If you have certified (“slabbed”) coins, you’re a step ahead, as these offer substantial protection, but proper safe storage of the slabs is still important. There are number of different storage options for slabs, including boxes supplied by the grading companies themselves.

If you want to start shopping for coin storage products, one of the companies I recommend is Wizard Coin Supply. The photo at top is an example of the products they offer. Or, as the ANA suggests, start with your local coin dealer or shop.
