Preserving War Nickels: A Conservationist’s Guide to Protecting America’s Silver War Coins

The Hidden Crisis in War Nickel Preservation

As a conservationist who has studied these coins for decades, I’ve witnessed a troubling pattern that threatens the future of war nickel collecting. I’ve seen too many valuable pieces ruined by improper cleaning or storage. Here is how to keep this safe for the next generation.

Understanding War Nickel Composition and Vulnerability

War nickels, minted from 1942 to 1945, contain 35% silver as a strategic metal replacement during World War II. This composition makes them particularly susceptible to toning, oxidation, and PVC damage. The large mintages of certain dates like the 1943-P have led many collectors to underestimate their preservation needs, but even “common” dates deserve careful handling.

The Toning Challenge: Friend or Foe?

Toning on silver coins occurs naturally through exposure to sulfur compounds in the air, developing beautiful rainbow hues over decades. While some collectors prize these patinas, others prefer brilliant surfaces. The key is understanding that toning is a natural process that can be preserved or removed, but never reversed once altered.

For war nickels showing early toning, store them in airtight holders with silica gel packets to control humidity. Avoid touching the surfaces with bare fingers, as skin oils accelerate toning and can cause permanent fingerprints. If you prefer brilliant surfaces, consult a professional before attempting any cleaning, as improper methods can permanently damage the coin’s surface and significantly reduce its numismatic value.

PVC Damage: The Silent Destroyer

Polyvinyl chloride (PVC) was once commonly used in coin flips and albums, but it poses a severe threat to silver coins. Over time, PVC breaks down and releases acidic gases that cause a distinctive green slime to form on coin surfaces. This damage is irreversible and can destroy a coin’s value completely.

Examine all storage materials carefully. Modern archival-quality holders are PVC-free and inert. If you discover coins stored in old PVC-containing materials, remove them immediately and store them in proper holders. Never attempt to clean PVC damage yourself, as this typically makes the problem worse.

Proper Holders: The First Line of Defense

Selecting the right holder is crucial for war nickel preservation. For individual coins, consider these options:

• Air-tite holders with gaskets for long-term storage
• Archival-quality flips for coins you handle frequently
• Acid-free cardboard 2×2 holders with Mylar windows
• Certified grading holders (slabs) from reputable services

For rolls and larger collections, use archival-quality tubes or boxes with proper cushioning. Avoid rubber bands, paper clips, or any materials that might trap moisture or chemicals against the coins.

To Clean or Not to Clean: The Eternal Question

This is perhaps the most controversial topic in coin preservation. My professional stance is simple: clean only when absolutely necessary and only using professional methods.

Most war nickels found in circulation or collections have already developed some toning or oxidation. Light surface dirt can often be removed safely with gentle methods like soaking in distilled water or using a soft brush. However, aggressive cleaning with abrasives, acids, or even some commercial coin cleaners can permanently damage the delicate silver surface.

Before cleaning any coin, ask yourself: Is this cleaning truly necessary? Will it improve the coin’s appearance without reducing its value? If you’re unsure, consult a professional numismatist. Remember that a properly preserved, naturally toned coin is almost always more valuable than one that has been harshly cleaned.

Storage Environment: The Overlooked Factor

Even with proper holders, the storage environment plays a crucial role in preservation. War nickels should be stored in a cool, dry place away from direct sunlight and temperature fluctuations. Ideal conditions include:

• Relative humidity between 40-50%
• Temperature between 60-70°F (15-21°C)
• Protection from air pollutants and sulfur compounds
• Minimal exposure to light, especially UV radiation

Consider using a dehumidifier in humid climates and avoid storing coins in basements, attics, or other areas prone to moisture or temperature extremes. A dedicated coin cabinet or safe provides the best protection.

Special Considerations for Key Dates and Varieties

Certain war nickels require extra attention due to their rarity or condition sensitivity. The 1944-S, for example, suffered significant attrition and high-grade examples are particularly valuable. The 1943/2 overdate, despite being considered common, deserves careful preservation as many examples have been destroyed through improper handling.

Key dates and high-grade specimens should be stored in the most protective holders available, preferably in certified grading holders. These provide both physical protection and authentication, which is crucial for valuable varieties.

Documentation and Insurance

Proper documentation complements physical preservation. Maintain detailed records of your collection, including purchase dates, prices, and any restoration work performed. Consider specialized coin insurance for valuable pieces, as standard homeowners’ policies often don’t cover numismatic items adequately.

Conclusion: Preserving History for Future Generations

War nickels represent a fascinating period in American history when the nation adapted its coinage to support the war effort. These coins, particularly the scarcer dates and varieties, are becoming increasingly difficult to find in nice condition due to decades of attrition and melting.

By following proper preservation techniques – using appropriate holders, controlling environmental factors, avoiding unnecessary cleaning, and understanding the specific needs of different dates and conditions – collectors can ensure these historical artifacts survive for future generations to study and appreciate.

The next time you handle a war nickel, remember that you’re not just holding a piece of silver, but a tangible connection to America’s wartime experience. Treat it with the respect and care it deserves, and it will reward you with both historical significance and potential financial appreciation for decades to come.
