In a place like Rockford, seasonal temperature changes and humidity levels can affect coin preservation. Whether you store coins at home or in a secure facility, protecting them from environmental damage is essential.

Here’s what to consider:

• Avoid extreme temperatures – Heat and cold can cause metals to expand, contract, or discolor.
• Control humidity – Too much moisture in the air can lead to corrosion, even in silver and gold coins.
• Use proper containers – Acid-free holders, capsules, and sealed boxes help reduce exposure.
• Store off the ground – Keep coins elevated in case of flooding or leaks.
• Avoid plastic bags – Some types contain PVC, which can damage coin surfaces over time.
• Inspect regularly – Check your coins a few times a year for signs of damage or changes in appearance.

Proper storage in Elgin’s changing climate protects the long-term value of your collection, whether you're keeping it for enjoyment or planning to sell later.
