Before attempting to polish a coin, it’s crucial to understand whether or not it’s a good idea, as cleaning collectible coins can significantly decrease their value. For collectible coins, it’s best to consult with a professional coin grading service or numismatist before cleaning, as the patina and natural toning can add to the coin’s value.
However, if you’re looking to clean common pocket change or coins that don’t hold significant collector value, here are some safe and effective methods:
The safest approach is to gently rinse the coin under a light stream of distilled water, holding it by the edges. Pat dry with a soft cloth or air dry, avoiding tap water due to potential minerals.
Common household items can be used for cleaning non-collectible coins:
- White vinegar: A mixture of vinegar and salt can help dissolve grime. Soak for a few minutes, gently scrub if needed (avoid on delicate coins), and rinse thoroughly with distilled water.
- Baking soda: A paste of baking soda and distilled water can be used with a soft cloth or toothbrush to gently rub the surface, followed by a thorough rinse and drying.
- Olive oil: A mild option for copper or bronze coins is soaking in olive oil for a period to loosen dirt, then rinsing and drying gently.
- Silver coins: Baking soda paste can be used for gentle cleaning of tarnished silver coins. Avoid abrasive silver polish.
- Copper coins: Olive oil is a safer option than acids for cleaning heavy tarnish on copper coins.
- Gold coins: Gold coins rarely tarnish and are best left mostly untouched, with a simple wipe to remove surface dirt if necessary.
- Cleaning valuable coins without professional advice is strongly discouraged as it can significantly reduce their value.
- Avoid using harsh chemicals or vigorous scrubbing, which can damage the coin.
- Always handle coins by their edges.
By using gentle methods and being cautious, you can clean coins effectively while preserving their condition.
