Preserving History: Expert Conservation Strategies for the 1970-S Small Date Lincoln Cent (PCGS MS65)

Let me share a hard-earned truth with fellow collectors: that 1970-S Small Date Lincoln Cent in your collection isn’t just pocket change – it’s a modern rarity begging for proper care. I’ve watched too many gems lose their numismatic value to well-meaning mistakes. Here’s how to preserve both this coin’s story and its market potential for future generations.

The 1970-S Small Date: Copper With Character

Why does this humble cent deserve museum-level attention? Struck during a blink-and-you-missed-it window at the San Francisco Mint, this variety whispers its rarity through that distinctive petite date font. PCGS population reports tell a sobering tale: only 2,296 examples graded across all conditions as of last count. When you’re holding one of the great minting anomalies of the 20th century, conservation isn’t optional – it’s your duty as a collector.

Preservation: Where Passion Meets Science

Remember the chatter about Ben The CoinGeek’s PCGS MS65 example? Those deep marks on Lincoln’s lapel sparked fierce debate, but here’s what matters most: every fingerprint, every moment in a subpar holder, chips away at history. Let’s armor your coin against its greatest enemies:

Toning: Beauty or Beast?

Bronze composition turns these cents into chemical time capsules. Watch for:

• Natural Patina vs. Chemical Crimes: That iridescent glow some coins develop? Pure numismatic poetry. But blotchy rainbows scream “storage disaster”
• The Sweet Spot: Stable humidity below 55% preserves surfaces. I keep silica gel packs with my collection – cheap insurance against environmental mood swings
• Golden Rule: Never try to “fix” toning. I’ve seen acetone baths turn six-figure coins into garage sale fodder

Oxidation: Copper’s Mortal Enemy

When your red-orange beauty starts browning like forgotten fruit:

• First Response: Isolate! That color shift means surface chemistry is raging
• Plastic Peril: Cheap holders are Trojan horses – we’ll expose their dirty secrets next
• Damage Control: Spot verdigris? This isn’t a DIY moment. I learned the hard way – call a pro before your coin becomes a science experiment

PVC: The Silent Collector Killer

Beware the green menace lurking in old flips:

• Sticky Situation: If your coin feels tacky or sports emerald streaks, you’ve got a PVC emergency
• Damage Control:
  1. Quarantine immediately – this stuff spreads like numismatic gossip
  2. Document everything – photos protect both provenance and value
  3. Seek professional detox – amateur cleaning attempts murder eye appeal
• Prevention Protocol: Only archival-grade “PVC-free” holders touch my collection

Choosing Armor: Holders Matter

Your coin’s first line of defense:

• Temporary Housing: Mylar-windowed Saflips (vinyl is verboten!)
• Forever Home: Air-tite capsules – the Fort Knox of protection
• Graded Glory: Never crack PCGS holders! They’re time capsules preserving both condition and credibility
• Environmental Warfare: My coins live in a humidity-controlled safe – attics and basements are where collectibility goes to die

The Cleaning Conundrum

About those shoulder marks on the MS65 specimen:

• Cold Hard Truth: Cleaning = collectibility suicide. Even microfiber can microscopically sandblast surfaces
• Market Reality: Professionally graded coins with cleaning evidence lose 30-70% of numismatic value overnight
• Last Resort: If mystery gunk appears (forum folks love theorizing “parking lot grime”), PCGS Restoration Services beats kitchen-table chemistry

Surface Marks: Reading a Coin’s Life Story

Those heated forum debates taught us:

• Origin Stories: Pre-strike quirks versus post-mint damage – proper storage prevents you from adding tragic chapters
• Design Danger Zones: Notice how Lincoln’s ear crevices trap contaminants? That’s why my holders get quarterly inspections
• Grading Wisdom: PCGS deemed those MS65 marks mint-original – your job is keeping them from worsening

Guardian of History

With just 209 examples graded MS65 or higher, every 1970-S Small Date cent is an irreplaceable artifact. Proper preservation maintains that breathtaking luster strike collectors will covet decades from now. Remember: in our world, true ownership isn’t possession – it’s stewardship. Protect that copper time capsule like the numismatic legacy it represents.
