How do you preserve medal collections?

How do you preserve medal collections to ensure they maintain their historical significance and monetary value for generations? Proper preservation requires a systematic approach combining environmental controls, appropriate storage materials, and regular maintenance protocols.

Environmental Control Essentials

Temperature and humidity are critical factors in medal preservation. Maintain a consistent temperature between 65-70°F (18-21°C) with relative humidity levels of 45-50%. Fluctuations can cause metals to expand and contract, leading to stress fractures or ribbon deterioration. Avoid basements, attics, and areas near heating/cooling vents.

Storage Solutions and Materials

Archival-Quality Materials

Use acid-free storage boxes, tissue paper, and polyethylene foam for cushioning. Never use PVC-based plastics, as they release harmful chemicals over time. Individual coin capsules or Mylar sleeves provide excellent protection for each medal while allowing visibility.

Display Considerations

If displaying medals, use UV-filtering glass and keep them away from direct sunlight. Rotate displayed items periodically to prevent uneven fading or deterioration.

Cleaning and Maintenance

Handle medals minimally and always wear cotton gloves to prevent oil transfer from skin. For cleaning, use only soft brushes and avoid harsh chemicals or abrasives. Document any cleaning activities with photographs and detailed notes.

Documentation and Insurance

Maintain detailed records including photographs, provenance information, and condition reports. This documentation proves invaluable for insurance claims and helps track any changes over time. Consider professional appraisals for valuable pieces.

Professional Conservation

For medals showing signs of corrosion, cracking, or significant wear, consult professional conservators who specialize in metallic artifacts. Attempting DIY repairs often causes irreversible damage.

Proper medal preservation combines science with careful attention to detail, ensuring your collection remains pristine for future generations. Whether you're preserving military honors or Olympic achievements, these fundamental principles will help safeguard your collection's legacy.
