Preserving History: Expert Conservation Tips for Your 1916 Buffalo Nickel (Including the Controversial PCGS#50731189 Example)

I’ve witnessed too many heartbreaking losses in our hobby – valuable pieces forever altered by improper cleaning or storage. Let’s discuss how to protect these irreplaceable artifacts. The recent uproar over the 1916 Buffalo Nickel (PCGS#50731189), mistakenly attributed as a doubled die obverse (DDO) before its dramatic auction withdrawal, perfectly illustrates how easily historical significance and numismatic value evaporate without proper preservation. As someone who’s handled thousands of coins, I’ll share conservation secrets to safeguard your pieces for future generations.

Historical Significance of the 1916 Buffalo Nickel

The 1916 Buffalo Nickel stands as a crown jewel of American coinage. Master sculptor James Earle Fraser’s revolutionary design (minted 1913-1938) introduced three elements that still captivate collectors today:

• A composite Native American portrait radiating stoic dignity on the obverse
• The legendary American bison “Black Diamond” immortalized on the reverse
• A durable 75% copper, 25% nickel composition that creates unique preservation challenges

The controversial PCGS-certified G04 specimen (#50731189) ignited collector forums when it appeared in GreatCollections auction #1995928 with a $1,000 opening bid. Sharp-eyed numismatists immediately spotted discrepancies in its purported doubled die obverse characteristics – particularly absent doubling in the ribbon ties, feather base, and date. This cautionary tale proves how environmental damage can obscure critical diagnostic features, turning what might have been a rare variety into a questionable specimen.

Identifying Key Markers: How Preservation Impacts Authentication

The Doubled Die Dilemma

Genuine 1916 DDO specimens display three unmistakable identifiers:

• Crisp separation in LIBERTY’s ribbon ties that appears “lifted” from the field
• Distinct doubling along the large feather’s base resembling ghost images
• Pronounced date doubling where the “1916” appears almost shadowed

The PCGS#50731189 piece lacked these definitive markers, with seasoned collectors noting its surfaces showed “no legitimate doubling patterns.” Forum discussions revealing “acid etching” damage suggest prior improper cleaning scoured away critical details – a sobering reminder of how easily collectibility evaporates when preservation fails.

Preservation Fundamentals: Guarding Your Buffalo Nickel’s Integrity

Toning: Nature’s Artwork vs. Environmental Assault

Natural toning develops through decades of delicate sulfur reactions with the nickel-copper alloy, creating prized rainbow patinas. However, the PCGS#50731189 specimen displays textbook environmental damage – uneven discoloration from improper storage. To preserve original surfaces:

• Use archival-quality flips (never PVC-based)
• Maintain steady humidity below 55%
• Store away from sulfur sources like cardboard or rubber bands

The Oxidation Menace

Those dreaded red spots on Buffalo Nickels? They’re copper oxidation fingerprints – the cardinal sin of improper storage. Our controversial G04 specimen shows advanced corrosion consistent with acid exposure. Fight back with:

• Air-tight capsules creating oxygen-free environments
• Silica gel packets strategically placed in storage areas
• Cotton gloves always – skin oils accelerate deterioration

PVC Damage: A Collector’s Nightmare

Old vinyl flips silently leach plasticizers that leave green, corrosive slime. While the auction photos show a modern holder, any prior PVC exposure could explain this coin’s ravaged surfaces. If you discover coins in flexible plastic holders:

• Immediately transfer to inert acrylic or Mylar (I prefer Saflip® holders)
• Seek professional conservation for residue removal
• Never attempt DIY cleanings – amateur efforts slash value

The Great Cleaning Debate: Why Acid Etching Destroys Numismatic Value

Forum experts identified our case study coin as “acid etched” – the nuclear option of coin cleaning that:

• Permanently erases original luster and surface texture
• Creates microscopic pores that accelerate future corrosion
• Destroys 90%+ of numismatic value (PCGS’ “Cleaned” designation exists for good reason)

As someone who’s mourned countless “cleaned to death” coins, I implore collectors:

• Never clean beyond gentle distilled water rinses (and only when absolutely necessary)
• Leave conservation to accredited professionals with museum-grade tools
• Remember: mint condition surfaces = maximum collectibility and historical value

Proper Holders: Armor for Your Numismatic Treasures

While the PCGS slab offers basic protection, true preservation requires more. For raw or slabbed coins:

• Choose NGC/PCGS holders over unverified third-party slabs
• Select inert materials: archival acrylic, polyethylene, or Mylar
• Avoid felt-lined albums (hidden acid migration risks)

For potential rare varieties like DDOs, consider:

• Climate-controlled display cases with UV filtration
• Intercept Shield® polymer sleeves that neutralize pollutants
• Bank vaults for long-term storage of high-value pieces

Value Guide: How Preservation Makes or Breaks Worth

Proper conservation creates gut-wrenching value differences for 1916 Buffalo Nickels:

• G04 (natural surfaces): $25-$50
• G04 (environmental damage): Barely $10-$20
• Authentic DDO in G04 with original patina: $1,500+

The PCGS#50731189 specimen’s $1,000 opening bid reflected attribution confusion, not market reality – proof that improper care compounds authentication issues. Well-preserved examples with intact eye appeal command 200%-500% premiums over cleaned counterparts, regardless of technical grade.

Conclusion: Our Duty as Historical Stewards

Every Buffalo Nickel – common date or rare variety – is touchable history. The PCGS#50731189 saga reminds us how quickly value vanishes when preservation fails. By adopting these practices:

• You safeguard numismatic integrity for future authentication
• Protect collector value through generations
• Preserve irreplaceable historical significance

Remember: we don’t own these coins – we guard them for those who’ll study them a century from now. As the forum sage wisely noted about high-grade DDOs: “That’s why I only collect 16 DD’s in MS-65 or better.” Let’s extend that philosophy beyond grade to include impeccable preservation standards. After all, true rarity lies not just in mintage numbers, but in survival quality.
