Preserving Buffalo Nickel Varieties: A Conservationist’s Guide to Proper Storage and Care

Historical Significance

The Buffalo Nickel, minted from 1913 to 1938, stands as one of America’s most cherished coin series. Featuring James Earle Fraser’s iconic design—a Native American on the obverse and an American bison on the reverse—these coins are a testament to early 20th-century artistry. For collectors aiming to preserve significant varieties for potential inclusion in reference works like the Cherrypickers’ Guide, mastering proper conservation techniques is paramount.

Understanding Toning and Oxidation

Toning on copper-nickel coins like Buffalo Nickels occurs naturally through exposure to sulfur compounds in the air, forming a protective layer that helps preserve the coin’s surface. However, improper storage can accelerate harmful oxidation, compromising the coin’s integrity. Buffalo Nickels, composed of 75% copper and 25% nickel, are particularly vulnerable to environmental damage. The copper content reacts with moisture and pollutants, potentially leading to verdigris—a greenish corrosion that can permanently mar the coin. Grasping this chemistry is crucial for effective preservation.

PVC Damage: The Silent Destroyer

Polyvinyl chloride (PVC), commonly found in older coin holders and flips, poses a significant threat. When exposed to heat and humidity, PVC degrades and releases acidic gases that cause irreversible damage, manifesting as a slimy green residue that eats into the coin’s surface. For Buffalo Nickel varieties you hope to submit for recognition in the Cherrypickers’ Guide, PVC damage is particularly catastrophic. The editors and graders examining your submission need to see the coin in its original state, without any chemical alterations that could obscure important variety markers.

Proper Holders and Storage Solutions

The optimal storage solution for valuable Buffalo Nickel varieties is archival-quality holders made from inert materials like polyethylene, polypropylene, or Mylar. These materials won’t react with the coin’s metal composition over time. For varieties you’re considering submitting to the Cherrypickers’ Guide team at cherrypickers@whitman.com, use individual capsules or flips that provide both protection and easy viewing. Avoid storing multiple coins together where they might contact each other and cause wear. Temperature and humidity control is equally important. Store your collection in a cool, dry place away from direct sunlight. Ideal conditions are around 65-70°F with 40-50% relative humidity. Consider using silica gel packets in storage areas to absorb excess moisture.

To Clean or Not to Clean: The Conservationist’s Perspective

This is perhaps the most critical advice I can offer: do not clean your Buffalo Nickels, especially if you’re hoping to have new varieties recognized. Cleaning, even with gentle methods, removes the natural patina and can eliminate important detail that variety specialists need to see. Bill Fivaz and J.T. Stanton, the authors of the Cherrypickers’ Guide, specifically look for original surfaces when evaluating new varieties. A coin with its natural toning, even if it appears slightly dull, is far more valuable for variety attribution than a bright, cleaned specimen. If your Buffalo Nickels have accumulated dirt or debris in the recesses, resist the urge to clean them. Instead, consult with a professional conservationist who specializes in numismatic preservation. They can advise on safe methods that won’t compromise the coin’s integrity.

Documenting Your Varieties

When you discover what you believe to be a new variety worthy of the Cherrypickers’ Guide, proper documentation is essential. Take high-resolution photographs under consistent lighting conditions. Note the coin’s grade, any distinguishing characteristics, and its provenance if known. The Cherrypickers’ Guide team welcomes submissions from collectors. As mentioned in the forum discussion, you can contact them directly at cherrypickers@whitman.com with your findings. They may request additional information or photographs to evaluate your discovery properly.

Case Study: Successful Variety Submissions

Looking at successful submissions can provide valuable insights. For example, collectors who have identified doubled die varieties like the 2015 WDDO-006, 2019 WDDO-011, and 2024 WDDO-002 Lincoln cents have followed a careful process of documentation and preservation. While these are Lincoln cents rather than Buffalo Nickels, the principles remain the same. The collectors who successfully had these varieties recognized maintained their coins in original condition, provided clear photographic evidence, and followed up with the variety attribution services.

Long-term Preservation Strategies

For collectors serious about preserving Buffalo Nickel varieties for future generations or potential publication, consider these long-term strategies:

• Maintain detailed records of your collection, including acquisition dates, sources, and any relevant historical information
• Use only archival-quality materials for storage and display
• Regularly inspect your collection for signs of environmental damage
• Consider professional grading for particularly significant specimens
• Join numismatic organizations to stay informed about best practices in conservation

Conclusion

The preservation of Buffalo Nickel varieties requires a delicate balance between protection and maintaining the coin’s original state. By following proper conservation techniques—using appropriate holders, controlling environmental conditions, avoiding cleaning, and documenting carefully—you increase the chances that your significant varieties will be recognized and preserved for future collectors. Remember that the numismatic community, including experts like Bill Fivaz, values originality above all else. A well-preserved, naturally toned Buffalo Nickel with a significant variety is far more valuable than a cleaned or damaged specimen, regardless of its rarity. Take the time to protect these pieces of American history properly, and you’ll be contributing to the ongoing story of coin collecting for generations to come.
