Best Storage Boxes for Medals You Aren't Displaying Yet

Which materials are archival-safe for long-term preservation of metallic decorations?

Materials that are chemically inert and free of sulfur or acidic additives provide the most reliable protection for metallic decorations over extended periods.

• Polyester film, such as Mylar, offers a transparent, chemically stable barrier that allows for viewing without exposing the metal surface to oils from human skin.
• Unbuffered tissue paper is preferred for silver or copper-based medals, as high-alkaline buffers can sometimes cause adverse reactions with specific reactive alloys.
• Polyethylene foam serves as a safe, non-reactive support material if it is high-density and free of plasticizers that might leach into the medal finish.
• Ethafoam provides a firm, inert structural base that won't off-gas or degrade when in direct contact with metal components.

How should ribbon materials be protected from light exposure and humidity?

Ribbons require complete darkness to prevent UV-induced fading and a stable environment to stop mold growth. Use unbuffered, acid-free tissue to wrap each ribbon, then place them in an opaque, archival-grade container. Many collectors assume that laminating a ribbon protects it from humidity, but this actually seals in moisture and traps acidic gases, which accelerates the deterioration of the silk or rayon fibers. Instead, rely on a climate-controlled room where the relative humidity remains steady, as this allows the natural fibers to breathe without risking the structural integrity of the fabric.

What are the benefits of using acid-free storage versus standard plastic containers?

Acid-free storage prevents the migration of harmful chemicals that cause pitting and discoloration, whereas standard plastic containers often off-gas volatile organic compounds.

Prioritize materials with these specific ratings to make sure your collection remains pristine for decades.

How can oxidation and tarnishing be prevented when storing medals in a box?

Preventing oxidation requires the removal of moisture and the neutralization of atmospheric pollutants that react with metallic surfaces to form tarnish.

• Silver cloth contains treated fibers that absorb sulfur compounds from the air, effectively creating a protective micro-environment around the metal.
• Corrosion intercept bags utilize copper-impregnated polymers to react with and neutralize corrosive gases before they can reach the surface of the medal.
• Microcrystalline wax provides a thin, invisible physical barrier that seals the metal from oxygen and airborne contaminants when applied sparingly to stable surfaces.
• Desiccant packs maintain an internal humidity level below 50 percent, which is the threshold where the rate of oxidation for most base metals significantly increases.

What is the recommended method for organizing multiple medals to prevent scratching?

Yes, you should store medals individually using custom-cut, acid-free board dividers to prevent surface-to-surface contact. Maintain a minimum gap of 2 centimeters between each item to make sure that even if a medal shifts, it cannot scratch the finish of its neighbor within the storage box.

Should medals be stored individually or in a collective display case?

Individual storage is superior to collective display cases because it eliminates the risk of medals clanking together or damaging each other's finishes. Using individual compartments allows you to tailor the environment for each piece, such as using specific tissue for silver versus bronze, which react differently to the air. For example, a heavy bronze star might scratch a delicate enamel badge if they are left to slide against one another in a shared tray.

The only exception is if your collection is housed in a professional-grade, custom-fitted cabinet with individual recessed slots that prevent any movement. Even then, you must make sure the display case material is archival-safe, as many mass-produced display cases use velvet or felt linings that contain adhesives and dyes that eventually stain or corrode the metal.

What environmental conditions are ideal for preventing degradation of metal and fabric components?

Maintain a consistent temperature between 18 and 22 degrees Celsius to prevent the expansion and contraction that weakens metal-to-ribbon attachments. Keeping the relative humidity strictly between 45 and 55 percent is the most effective way to stop both metal oxidation and the growth of mold on fabric ribbons.

Are there specific storage box features that provide better security for valuable or sentimental items?

Security-focused storage boxes often feature reinforced corners and locking mechanisms that prevent accidental opening or unauthorized access to sentimental items. A heavy-duty, drop-front box made of triple-walled, acid-free corrugated board provides structural rigidity that protects medals from being crushed if other items are stacked on top of them during storage. For instance, a metal-reinforced edge prevents the box from warping over time, which keeps the lid airtight and secure.

The nuance here is that while security is important, you must avoid locking mechanisms that use internal metal springs or lubricants that might off-gas into the box interior. If you require high-level security for a valuable collection, store these archival boxes inside a fire-resistant safe that has been properly ventilated to avoid the buildup of stagnant, humid air.
