Dos of Coin Cleaning and Maintenance

When it comes to cleaning and maintaining your coins, there are several dos that you should follow:

1. Handle Coins Properly:

  • Wear Gloves: To avoid leaving fingerprints or oils on the coins, always wear gloves or use plastic tweezers when handling them.

  • Use Distilled Water: If you decide to clean your coins, use distilled water that is free from impurities. Avoid tap water, as it may contain chlorine or other chemicals that can damage the coin's surface.
  • Use Soft Brushes: When cleaning, use soft brushes made of natural fibers, such as camel hair brushes or soft bristle toothbrushes. Gently brush the coin's surfaces to remove loose dirt or debris.

4. Seek Professional Help:

  • Consult a Professional Grading Service: If you have valuable or rare coins, consider seeking advice from a professional grading service. They can provide guidance on proper cleaning techniques or recommend conservators who specialize in coin restoration.
