Identifying and Cleaning Found Coins: A Guide for Metal Detecting Enthusiasts
Metal detecting is an exciting hobby that allows you to discover hidden treasures from the past. One of the most common finds while metal detecting is coins, which can provide valuable insights into history. However, these coins often come out of the ground covered in dirt and grime. In this guide, we will discuss how to identify different types of coins and share effective cleaning methods to restore their shine.
1. Identifying Coins:
Before diving into cleaning techniques, it’s crucial to be able to identify the type of coin you have found accurately. Here are some steps you can follow:
a) Observe the Design: Carefully examine both sides of the coin for inscriptions, symbols, or figures. Note any identifying marks like dates or mint marks.
b) Research Online Resources: Take advantage of online databases and numismatic websites that offer comprehensive information about various types of coins. These resources often include detailed images and descriptions that can help with identification.
c) Seek Expert Opinions: If you’re unable to identify a particular coin on your own, consider reaching out to local coin clubs or professional numismatists who can assist with identification.
2. Cleaning Methods:
Once you have identified your found coin, it’s time to clean it gently without causing any damage or diminishing its value. Here are a few tried-and-true methods:
a) Warm Water Bath: Fill a bowl with warm water (not hot) and add a mild dishwashing detergent or liquid soap. Let the coin soak for several minutes before using a soft-bristled toothbrush or cotton swab dipped in soapy water to remove loose dirt from its surface.
b) Olive Oil Soak: For more delicate coins made from materials like silver or copper, an olive oil soak can be effective in loosening dirt without causing harm. Submerge the coin in olive oil for a few hours or overnight, then gently brush away the dirt with a soft toothbrush. Rinse the coin with warm water and pat dry.
c) Lemon Juice and Salt: This method is suitable for removing tarnish from copper or bronze coins. Create a paste by mixing lemon juice and salt until you achieve a gritty consistency. Apply the paste to the coin using a cotton swab or soft cloth, rubbing gently in circular motions. Rinse thoroughly with warm water and pat dry.
d) Baking Soda Solution: To remove stubborn stains without scratching the coin’s surface, create a baking soda solution by mixing one tablespoon of baking soda with hot water. Soak the coin in this solution for a few minutes before gently scrubbing it with a soft toothbrush or cloth. Rinse well and dry carefully.
3. Precautions:
While cleaning your found coins, keep these precautions in mind:
a) Never use abrasive materials like steel wool, scouring pads, or harsh chemicals as they can damage the coin’s surface irreversibly.
b) Avoid excessive rubbing or scrubbing as it may wear off delicate details on old or valuable coins.
c) If you’re uncertain about cleaning methods for specific coins, consult an expert before attempting any restoration techniques.
4. Coin Preservation Tips:
Once you have successfully cleaned your found coins, it’s essential to store them properly to maintain their condition:
a) Coin Holders: Invest in quality plastic holders designed specifically for storing and protecting coins. These holders are available in various sizes to accommodate different types of coins.
b) Acid-Free Paper Flips: For long-term storage, consider placing individual coins inside acid-free paper flips before inserting them into plastic holders. The flips help prevent direct contact between the metal surface of the coin and plastic material.
c) Display Cases: If you wish to showcase your collection, opt for display cases made from materials such as acrylic that offer protection from dust and moisture while allowing visibility.
d) Handle with Care: Always handle coins by their edges to avoid leaving fingerprints or oils on the surface. The natural oils from our skin can cause damage over time.
By following these identification and cleaning techniques, you can turn your found coins into shining pieces of history while preserving their value for years to come. Happy metal detecting!
