The Acid Test: Preserving Buffalo Nickels and the Ethics of Alteration

Have you ever held a piece of history in your palm, only to watch its numismatic value vanish from a single misguided decision? As someone who’s spent decades preserving coins, I’ve witnessed too many treasures damaged by improper cleaning. Let’s explore how to protect these artifacts – starting with a fiery debate raging through collecting forums about a 1913-S Buffalo Nickel that crossed a dangerous line.

Acid Treatment: A Controversial “Solution” for Buffalo Nickels

Buffalo Nickels (1913-1938) break collectors’ hearts. Their weak strikes and high relief made dates wear into oblivion faster than ice cream melts in Phoenix. Enter acid treatment – the nuclear option where collectors bathe coins in corrosive solutions to “restore” details. When forum user basetsb demonstrated this on a worn 1913 specimen, the bison’s vanished horn reappeared like a ghost from the metal.

“This chemical resurrection comes at a terrible cost,” one member lamented. “That horn isn’t original – it’s Frankenstein’s monster carved by acid.”

From my conservation bench, acid treatment isn’t restoration – it’s alchemy gone wrong. The process dissolves metal, creating artificial canyons where natural wear once told the coin’s story. Yes, rare dates like the 1918/7-D might gain temporary market appeal, but purists (myself included) see only murdered patina and lost provenance. That “revived” nickel? Its century of honest circulation history was erased in a chemical bath.

The Grading Quandary: When Labels Become Lies

When ICG slabbed our controversial nickel as “AU, Acid Treated,” battle lines formed faster than a 1933 double eagle auction. Here’s the rub: traditional grading evaluates original surfaces – luster, strike quality, natural toning. Acid treatment annihilates these irreplaceable traits.

As veteran dealer ArizonaRareCoins argued: “Slabbing this as AU is like calling a taxidermied lion ‘sleeping.’ The eye appeal might fool you momentarily, but the essence is gone.” Modern third-party graders wisely use “Details” designations (e.g., “Genuine – Acid Treated”) – a crucial transparency that protects buyers while acknowledging reality.

Preservation vs. Desecration: Drawing the Line

Let’s be crystal clear where conservation ends and vandalism begins:

• Preservation: Gentle removal of surface contaminants using museum-approved techniques. We’re talking distilled water swabs, not dental picks. Goal: Reveal existing details without altering the strike.
• Alteration: Any process changing the coin’s fundamental nature. Acid baths, whizzing, re-engraving – these aren’t restoration, they’re numismatic sacrilege that murders collectibility.

Our acid-dipped Buffalo Nickel? It’s now a chimera – part 1913 mint strike, part 21st-century chemical experiment. The original surfaces that collectors prize? Obliterated forever.

Guardianship 101: Protecting Your Pieces

Even altered coins deserve proper care. Here’s how to shield your collection from silent killers:

• PVC Peril: Those flexible plastic flips? Many contain polyvinyl chloride that slowly excretes acid, etching coins with green goo worse than a teenager’s neglected gym clothes.
• Safe Havens: Mylar flips. Hard acrylic holders. Archival-quality slabs. These inert materials preserve luster without chemical warfare.
• Environment Control: Store coins where you’d store fine wine – stable temperatures, low humidity, zero sunlight. Silica gel packs are cheap insurance against environmental betrayal.

The Golden Rule of Coin Care

Repeat after me: “When in doubt, don’t touch it!” That milk spot? Those carbon flecks? They’re part of your coin’s biography. Harsh cleaning:

• Scrubs away natural toning (the rainbow patina collectors adore)
• Etches microscopic hairlines visible under magnification
• Triggers accelerated corrosion like opening Pandora’s box

Our acid-treated Buffalo Nickel proves how “improving” coins often destroys them. Unless you’re a professional conservator with a PhD in metallurgy, hands off the Q-tips!

Rarity vs. Reality: The Acid-Treated Market

What’s an altered Buffalo Nickel worth? Forum estimates ranged from $15 (common dates) to $1,000+ for rare varieties like the 1916 doubled die. While tempting for budget collectors, remember:

These coins plateau in value. They’ll never command mint-state premiums or make auction headlines. Their collectibility hinges entirely on transparent disclosure – hence the critical importance of reputable grading labels that shout “ALTERED!” from the rooftops.

Conclusion: Honoring the Journey

That acid-treated 1913-S Nickel represents more than metal – it’s a morality play about our role as history’s custodians. Do we value accessibility over integrity? Convenience over preservation?

As collectors, our sacred duty is clear:

1. Educate: Learn to spot alterations like acid etching or artificial toning
2. Preserve: House coins in archival materials worthy of their age
3. Resist: Fight the temptation to “improve” what time has wrought

Whether you display mint-state rarities or circulated survivors, honor the journey these coins have made. Protect their stories. Preserve their numismatic soul. Future generations will hold these artifacts and know we cared enough to protect them – acid-free.
