The best way to clean your coins is not to clean them. When people want to sell their old coins, they want to make the coins look as beautiful as possible to get a good price. This may apply to cars, bikes or smartphones, but not to coins. For older coins, signs of aging and distortion can increase the value of a coin and make it more attractive to collectors.

Coins are valued by collectors based on a number of different factors, ranging from the scarcity of the currency, the date, the minting of the currency in which it was produced, and of course the status of the coin. The condition is not about dirt or dirt, but about potential damage. Many collectors even want patina to appear on coins. This is a kind of green layer that has formed on coins/metals over the years. You should never clean old coins yourself, as removing the patina can significantly affect the value of the coin. Cleaning causes 99 percent of coins to lose their value.

If you still want to clean your coins, you should just rinse your collection with a soft brush and water. It is very important not to dry the coins with a cloth, as friction can remove small parts of the engraving.

What is the best way to clean your coins?

Cleaning coins is a delicate process, and it’s important to approach it with caution to avoid damaging the coins and preserving their historical or numismatic value. In general, it’s often recommended not to clean coins, especially if they have numismatic or collector’s value, as cleaning can diminish their condition. However, if you have common coins or those in circulation that you want to clean, here are some gentle methods:

Mild Cleaning Methods

Warm Soapy Water

Fill a bowl with warm (not hot) water and add a small amount of mild dish soap.
Gently immerse the coins and let them soak for a few minutes.

Use a soft toothbrush or your fingers to gently brush away dirt or residue.
Rinse the coins thoroughly with clean water and pat them dry with a soft cloth.

Cleaning of metals by electrolysis

Olive Oil Bath

Place the coins in a small dish and cover them with olive oil.
Let the coins soak for a few hours or overnight.
Remove the coins and gently wipe away the oil with a soft cloth.

Baking Soda Paste

Make a paste by mixing baking soda with water until it forms a thick consistency.
Gently rub the paste onto the coins using a soft cloth or a soft toothbrush.
Rinse the coins thoroughly with clean water and pat them dry.

Avoid Harsh Cleaning Methods

Metal Polish or Abrasive Cleaners

Avoid using metal polish or abrasive cleaners, as they can scratch and damage the surface of the coins.

Vinegar or Lemon Juice

Acidic substances like vinegar or lemon juice can corrode coins over time, so it’s best to avoid using them for cleaning.

Rubbing or Buffing

Avoid rubbing or buffing coins with abrasive materials, as this can cause scratches and wear.

Ultrasonic Cleaners

Ultrasonic cleaners are not recommended for coins, as they can cause damage and may remove the patina.

Tips for Preserving Value

Handle with Gloves

Wear cotton gloves to avoid leaving oils or fingerprints on the coins.
Minimal Handling:

Minimize handling of coins, especially valuable or rare ones, to prevent wear.

Consult Professionals

If you have valuable or ancient coins, consider consulting a professional coin conservator or numismatist before attempting any cleaning.

Always remember that cleaning coins can impact their value, and in many cases, it’s best to leave them in their natural state. If you have coins with historical or collector’s value, it’s advisable to consult with experts before attempting any cleaning to avoid unintentional damage.
