If you've recently purchased a lot of collectible world coins—like the curated coin assortments offered at Erickson Life—you might be tempted to shine them up to make them look brand new. After all, who doesn’t love the gleam of polished metal?

But here’s the truth: when it comes to collectible coins, cleaning them can do more harm than good—especially if done incorrectly.

In this post, we’ll explain how to clean collectible coins the right way, when (and when not) to clean them, and the best practices for preserving their condition without risking their value.

Should You Clean Collectible Coins at All?

Before we talk techniques, let’s address the big question: should you clean collectible coins?

In most cases, the answer is no.

Collectors and appraisers value coins not just for their appearance, but for their authenticity, age, and natural patina. Improper cleaning can:

• Scratch the surface

• Remove original toning

• Decrease historical or monetary value

• Leave behind chemicals or residue

That said, if the coins are heavily soiled, encrusted with debris, or you're simply collecting them for fun rather than investment, light cleaning using gentle methods can be acceptable—especially for bulk coins like our Lot of Collectible World Coins.

When Is It Okay to Clean Coins?

You might consider cleaning coins if:

• They’re covered in dirt, mud, or organic residue

• They’ve been exposed to water or environmental damage

• You want to identify faint markings or dates

• They’re part of a non-rare, non-investment bulk collection

If your collection includes modern world coins, damaged pieces, or duplicates, these are typically safe candidates for cleaning.

What NOT to Do When Cleaning Coins

Let’s start with a few don’ts—because improper cleaning is the fastest way to ruin a good coin.

• ❌ Never use abrasive cleaners, scrubbing pads, or toothbrushes

• ❌ Avoid vinegar, lemon juice, or other acidic solutions

• ❌ Don’t use metal polishes or household chemicals

• ❌ Never polish coins with cloths designed for jewelry or silverware

These methods may make coins “shinier,” but they strip away originality and leave micro-scratches that drastically lower value.

How to Clean Collectible Coins: Safe Methods

If you’ve determined it's okay to clean a few coins, follow these gentle steps:

1. Start with a Water Soak

Place coins in distilled water (never tap water, which contains minerals) and soak them for several hours—or even a full day. This loosens dirt without harsh chemicals.

2. Rinse Gently

Use a soft stream of warm water to rinse the coin. Avoid rubbing. If debris remains, repeat the soak.

3. Use Mild Soap (Optional)

For stubborn grime, add a small drop of mild dish soap to the distilled water. Gently agitate the water—do not scrub the coin directly.

4. Pat Dry with Care

Place the coin on a clean, soft cloth or towel. Pat dry—never rub. Let the coin air dry completely before storage.

Pro tip: Use cotton gloves while handling coins to avoid fingerprints and oils.

What About Tarnish or Toning?

Many older coins, especially silver ones, develop a surface film called toning. This natural discoloration is often valued by collectors and should not be removed unless you're dealing with a damaged or common coin for personal display.

If you’re unsure whether you’re looking at toning or corrosion, it’s best to consult a professional before cleaning.

Storing Your Coins After Cleaning

Once your coins are clean (or even if you decide to leave them as-is), proper storage is key to preserving condition.

Recommended Storage Options:

• Coin flips or holders (PVC-free)

• Airtight capsules for higher-value coins

• Albums or folders for easy browsing

• Desiccant packets to control moisture

Always store coins in a cool, dry place—away from direct sunlight, humidity, or fluctuating temperatures.
