Unearthing Hidden Treasures: Mastering the Art of Cleaning and Preserving Metal Detecting Coins
Cleaning and Preserving Coins Found While Metal Detecting
Metal detecting can be an exciting hobby that often leads to discovering interesting artifacts, including coins. Whether you stumble upon a rare coin or just find some old change, it’s important to know how to properly clean and preserve these treasures. In this article, we will provide you with detailed information on the best practices for cleaning and preserving coins found while metal detecting.
1. Cleaning Coins:
Before starting the cleaning process, it is crucial to understand that cleaning can potentially damage the coin’s value if done incorrectly. It’s always recommended to consult with a professional numismatist before attempting any aggressive cleaning methods.
a) Dry Cleaning: The safest method is dry cleaning, which involves gently brushing off dirt and debris using a soft-bristle toothbrush or a non-abrasive brush specifically designed for numismatic purposes. Avoid using any chemicals or abrasive materials during this process.
b) Soaking Method: If dry cleaning doesn’t yield satisfactory results, soaking the coin in distilled water may be considered. Fill a container with distilled water (avoid tap water due to impurities) and place the coin inside for 24-48 hours. Gently agitate the water occasionally without touching the coin directly.
c) Chemical Cleaning: Chemicals should only be used as a last resort when all other methods fail and under professional guidance. If necessary, mild solutions like acetone or baking soda mixed with distilled water can be applied sparingly on stubborn stains using cotton swabs or soft brushes.
2. Preservation Techniques:
Preserving your discovered coins in their current condition ensures their longevity and potential future value appreciation:
a) Do Not Clean Patina: Many collectors appreciate coins’ natural patina – the thin layer of oxidation that forms over time – as it adds character and authenticity. Do not attempt to remove patina unless advised by an expert.
b) Proper Storage: Store your cleaned coins in individual coin holders made of acid-free materials, such as Mylar flips or cardboard 2x2s. Avoid PVC-based holders, as they can cause damage over time. Place the holders in airtight containers or albums designed for numismatic preservation.
c) Handling with Care: Always handle coins by their edges to avoid transferring oils and acids from your skin. Fingerprints can degrade a coin’s surface over time.
3. Identifying Valuable Coins:
While cleaning and preserving your coins is essential, it’s equally important to identify potentially valuable ones before taking any cleaning actions:
a) Research: Conduct thorough research on the coins you find using books, online resources, or consulting experts in numismatics. Understanding the historical context and rarity of a particular coin will help determine its value.
b) Seek Expert Opinion: If you believe you have found an exceptionally rare or valuable coin, seek out advice from professional numismatists who can verify its authenticity and provide guidance on appropriate cleaning methods if necessary.
4. Legal Considerations:
It’s crucial to be aware of any local laws regarding metal detecting and keeping discovered artifacts, including coins:
a) Obtain Permits: Some areas require permits for metal detecting activities. Make sure to obtain all necessary permits and follow specific regulations to avoid legal issues.
b) Reporting Finds: In some cases, particularly when discovering ancient or historically significant coins, it may be mandatory to report your finds to relevant authorities or archaeological organizations. Familiarize yourself with local laws concerning antiquities.
In conclusion, cleaning and preserving coins found while metal detecting requires caution and knowledge in order not to damage their value. Dry cleaning is usually sufficient for removing dirt and debris; however, more aggressive methods should only be used under professional guidance as a last resort. Proper storage techniques help preserve the condition of cleaned coins while handling them with care prevents further damage. Lastly, identifying potentially valuable coins through research and seeking expert opinions is essential, while adhering to legal requirements ensures a responsible and enjoyable metal detecting experience.
