Cleaning coins may seem like a way to improve their appearance, but it often does more harm than good. In Elgin, many collectors unintentionally lower their coin’s value by removing surface details or causing micro-scratches during cleaning.

Here’s what to avoid:

• Don’t use household cleaners – Even mild products can react with metal and damage the surface.
• Never scrub coins – Abrasives wear down fine details that matter for grading.
• Avoid soaking in vinegar or acids – These can cause discoloration and destroy original patinas.
• Be cautious with online “cleaning hacks” – Many DIY tips are not suitable for numismatic preservation.
• Don’t polish proof or high-grade coins – Original mint luster is often more valuable than a shiny finish.

If you think a coin needs cleaning, consult with a knowledgeable professional first. In most cases, it’s better to leave coins as-is and allow a rare coin dealer in Elgin to assess condition without interference.
