When you sell clothes to a consignment store or trade in your old car, you are probably used to preparing your investments by making sure they’re in pristine condition. However, some objects can be devalued by a good cleaning. If you are an aspiring coin collector, for example, consider the following reasons not to polish your coins.

3 Reasons to Leave Your Coins Uncleaned

1. Coin Collectors Prefer Uncleaned Pieces

While you might consider your coin collection one of your most prized possessions at the moment, there may come a time when you want to sell it—whether because your collection has become too big or you need some extra funds. Even if you never plan to get rid of your old coins, it is best to prepare for the possibility. In the marketplace, coin collectors favor uncleaned coins that still have their natural coloring, including any tarnishing that may have developed over time.

2. Patina Demonstrates Age

While some objects, like cars and china, are better off being cleaned and polished to a bright shine, coins wear their discoloration like a badge of honor. The gradual deterioration that develops over time, also known as patina, is proof of a coin’s age—which is where the intrigue of historical, rare currency lies. While a well-preserved coin is admirable, a coin that has been aggressively cleaned is not.

3. Uncleaned Coins Are Worth More

Should you ever decide to sell your coin collection, you will be happy you stayed away from cleaning solutions. Uncleaned coins are worth more than their polished alternatives. If you scrub your collection so hard that you leave nicks and scratches in the outermost layer, the coins will lose their shine and a significant amount of their value.
