Protect Your Collection • The Coin Shop
Cleaning a coin almost always lowers its value — sometimes dramatically. Even “gentle” methods can cause permanent damage. Leave cleaning to professional conservation services only when absolutely necessary.
Always hold coins by the edges using clean cotton gloves or coin tweezers. Never touch the faces or surfaces — skin oils cause spotting and toning over time.
Use acid-free flips, capsules, or albums. Store in a cool, dry, dark place. Add silica gel packets to absorb moisture and prevent tarnish.
Keep coins away from extreme temperature changes, humidity, direct sunlight, and household chemicals. A stable environment is the best protection.
For valuable coins, consider professional grading (PCGS or NGC). Store in a quality home safe or locked cabinet.
