A great collection deserves great protection. Improper storage can cause toning, spotting, corrosion, or damage that destroys value. Here’s the 2026 guide to keeping your coins in top condition.
Best Storage Options
- 2×2 Cardboard Flips – Inexpensive, good for circulated coins. Use Mylar windows (not PVC).
- 2×2 Plastic Capsules – Airtight, clear, great for silver and gold.
- Slabs (PCGS, NGC, ANACS) – Professional grading + hard plastic protection. Best for valuable coins.
- Albums & Folders – Whitman, Dansco, or Lighthouse for circulated sets. Avoid cheap vinyl pages (PVC damage).
- Coin Boxes & Trays – Mahogany or plastic trays with velvet inserts for display.
- Safe or Safety Deposit Box – For high-value collections. Use silica gel packets to control humidity.
Key Protection Rules
- Never clean coins – Cleaning removes natural toning and reduces value dramatically.
- Handle by edges – Use cotton gloves or hold by rim to avoid fingerprints/oils.
- Control environment – Store at 40–60% humidity, 65–70°F, away from direct sunlight.
- Avoid PVC – Plastic pages or flips with PVC can leach chemicals and ruin coins.
- Inventory & photograph – Keep a spreadsheet or app record with photos, dates, grades, and values.
2026 Tip: Use airtight Intercept Shield bags or capsules with anti-tarnish strips for silver coins—they prevent tarnish for years.
Protect your coins properly and they’ll reward you for decades.
