Whether you’re a seasoned collector or new to the world of coins, one thing remains essential: proper storage. Coins—especially rare or valuable ones—can lose value if they’re scratched, tarnished, or exposed to the wrong conditions.

Storing your coins the right way isn’t just about organization—it’s about preserving their condition, value, and history for years to come.

At PGS Gold & Coin, we’ve helped thousands of collectors and investors in Chicago protect and manage their coin collections with expert guidance. Here’s what you need to know to do the same.

Why Proper Coin Storage Matters

Coins are sensitive to:

  • Moisture, which can cause corrosion or spotting
  • Air pollutants, including sulfur and oxygen, which can tarnish metal
  • Physical damage from handling or contact with other objects
  • Temperature changes, which can create condensation or damage packaging

Improper storage can dramatically reduce a coin’s market value, even if the damage seems minor.

 

Best Practices for Coin Storage

1. Handle with Care

Always hold coins by the edges—never the faces. Use cotton gloves if handling high-value or proof coins.

2. Use Proper Containers

The best storage options include:

  • Individual coin holders (2×2 flips, Mylar flips, or cardboard holders)
  • Coin capsules – airtight, hard plastic cases perfect for high-value coins
  • Albums and folders – ideal for organizing and protecting circulated collections
  • Coin tubes – efficient for storing bullion or bulk coins of the same size

Avoid PVC-based plastic flips, which can release chemicals over time and damage coins.

3. Control Environment

  • Store coins in a cool, dry place—ideally between 60–70°F with low humidity
  • Use silica gel packs to absorb moisture
  • Avoid attics, basements, or anywhere with temperature swings or water exposure

4. Limit Exposure to Air and Light

Keep coins sealed or enclosed. Oxidation and UV rays can tarnish silver and other metals.

5. Keep an Inventory

Maintain a detailed list or digital catalog of your coin collection, including purchase dates, grades, certifications, and values. This is essential for insurance, resale, or estate planning.

Safe Deposit Box vs. Home Storage

  • Home Safes: Great for easy access and everyday collectors. Choose a fireproof, waterproof safe stored in a secure area.
  • Bank Safe Deposit Boxes: Ideal for high-value or long-term storage. However, limited access and no FDIC insurance for contents are considerations.
