Why Proper Coin Storage Matters
How you store coins has a direct impact on their condition, resale value, and overall longevity. Improper storage may expose coins to moisture, temperature shifts, and physical damage, reducing their value even if they’re otherwise rare or desirable.
Follow these best practices:
- Use protective holders – Hard plastic capsules or archival-safe sleeves prevent contact and minimize environmental exposure.
- Avoid PVC materials – Plastic that contains PVC can cause long-term chemical damage to coins.
- Store in a stable climate – Temperature and humidity control helps prevent toning, corrosion, or mold.
- Limit handling – Hold coins by the edges only and avoid touching the surface with bare hands.
- Keep away from contaminants – Store coins separately from items like paper, cardboard, or treated wood that may emit damaging vapors.
Good storage protects both common and rare pieces, preserving their condition for display, resale, or long-term investment.
