Collecting items is a pastime that's been popular throughout the ages. Coins are popular collector's items that people young and old can enjoy. Finding rare coins and growing your collection over time can bring incalculable joy. Whether you're interested in selling your coin collection or you'd simply like to know its worth, a professional appraiser can give you an accurate quote. These are four factors that can affect the overall value of your coin collection:

1. Materials

The material a coin is made of affects its overall value. Nickel is the least valuable material, while copper is worth more. Gold and silver coins are often worth more than their face value due to their precious metal content. Coins made of precious and semi-precious metals may be valued by weight. If you're interested in selling your coin collection, you may want to consider selling your gold and silver coins to a metal buyer who will pay you by the gram.

2. Size

The size of your coin collection will have an impact on its overall value. For instance, large coin collections may be more likely to contain valuable coins. Additionally, large coin collections typically contain more valuable metals by weight. This is good news for people who have been collecting coins for years and have amassed impressive collections during that time.

3. Age

The age of a coin can affect its value. As with most objects, antique coins are often worth more than they were at the time of their minting. However, not every old coin is worth large sums of money. A coin appraiser can look at your coin collection to find old coins that are especially valuable. Old coins that are in good condition are more likely to fetch a higher price than coins that have been damaged by wear and tear. For this reason, keeping your coins in a container designed to protect them from skin oils, ultraviolet rays, and contaminants can help you safeguard the value of your coin collection.

4. Rarity

Rarity plays a large role in the overall value of a coin. Some coins were minted in small quantities, which makes them exceptionally rare and valuable. Other coins are misprints that are ironically worth more than their correctly minted counterparts. Coin appraisers have a good working knowledge of rare and valuable coins. They'll be able to tell you which coins in your collection are worth money based on their rare status.
