When storing coins in a coin collection (or if you own a small amount of valuable coins), be careful who knows about these valuables. These are one of the top targeted items that puts society at risk for burglary and crime. If coins are not stored properly, it can cause corrosion, contamination, and their value to be lost forever. Today we are going to discuss general rules for storing coins, and different methods to be used for your coin storage.
Coins come in many different sizes, and can range from having little value to being worth thousands of dollars depending on the coin. These rules should be applied when storing coins. Make sure when storing your coins, you store them in a constant, moderate temperature, with low humidity. You should avoid storing in basements or attics that get too hot, unless they are climate controlled. Oxidation can occur if coins are exposed to air for a long period of time. This can cause the coins to discolor. Placing silica gel packs near the storage area can help control the moisture.
There are many different types of storage methods depending on your needs (long-term storage, or short-term storage).
For high value coins, you may want to consider keeping your coins in a safe deposit box or a fireproof home safe. For coins that are not of high value, you may use album folders, and paper envelopes to store your coins. Coin books are also used, but are not recommended for high value coins. It is not recommended to store your coins in bags, jars, misc containers unless you are keeping coins for saving money and are not concerned about the coins getting scratched or nicked up. Long term storage in any of these storage methods, can cause coins to discolor and damage over time.
Tubes or Plastic containers can hold a number of coins, and are good for bulk coin storage but the coins cannot be viewed without removing.
Coin albums and flips lined with mylar are the best and most popular method for storing coins. When it comes to flips and albums, it is best to stay away from the soft ones as they can contain PVC (or chloride), and this can cause decomposition to the coins. The mylar is not made of PVC but be careful when putting coins in these flips or albums and carefully handle them as if you are not this can cause nicks to the coins also.
Slabs are a sealed hard plastic holder. These are the safest method for your most expensive or valuable coins. These are best used for long-term storage, and are more expensive method of storing coins. You can use for individual coins or small sets of coins.
All of these methods can be used for coin storage, remember temperature and atmosphere is important to remember, and make sure you know the value of your coins before choosing which option storage you want to go with.
