Coin Care Guide

Protect Your Collection • The Coin Shop

Rule #1

Never clean a coin

Cleaning almost always lowers value — sometimes dramatically. Even “gentle” methods can cause permanent damage. Leave cleaning to professional conservation only when it is truly necessary.

How to properly care for your coins

Good habits protect both collector value and the look of your pieces. These are the practices we recommend in the shop every day.

Proper handling

Hold coins by the edges with clean cotton gloves or coin tweezers. Never touch the faces — skin oils cause spotting and toning over time.

Safe storage

Use acid-free flips, capsules, or albums. Store cool, dry, and dark. Silica gel helps control moisture and tarnish.

Environment

Avoid extreme temperature swings, humidity, direct sun, and household chemicals. Stability is the best protection.

Long-term

For valuable coins, consider professional grading (PCGS or NGC). Store in a quality home safe or locked cabinet.

Common mistakes to avoid

  • Household cleaners, toothpaste, or polishing cloths
  • Paper envelopes or ordinary plastic bags
  • Touching the surface of the coin
  • Kitchen or bathroom humidity
  • Stacking coins directly on top of each other

When to come see us

Unsure whether a coin should stay raw, go into a capsule, or be submitted for grading? Bring it in during business hours (Tue–Fri 10–4, Sat 10–2). We will give practical advice — and we stock the flips, capsules, and albums most collectors need.

Should I clean this coin before I sell it?

Almost never. Cleaning usually reduces what a dealer or collector will pay. Bring it as-is and let us evaluate it honestly.

PVC flips — are they safe?

Long-term storage in soft PVC can damage coins. Prefer inert holders and quality flips; ask us what we stock for your coin size.

Is professional grading worth it?

It depends on value, rarity, and condition. We can help you weigh submission costs against potential upside before you ship anything.
