Preserving Your IKE Dollars: Expert Conservation Tips to Protect Value and History

There’s a special ache that comes from seeing history damaged through well-meaning mistakes. As a conservationist who’s handled thousands of modern coins, let me share some hard-earned wisdom about preserving Eisenhower dollars—particularly those prized 1972 Type 1 and Type 3 varieties that make collectors’ hearts race. These magnificent coins deserve better than chemical baths and PVC prisons!

Understanding the IKE Dollar’s Historical Significance

Born during America’s space race and struck from 1971-1978, Eisenhower dollars represent our last circulating large-size dollar coin. What makes them endlessly fascinating to collectors? Let’s examine their composition:

• 1971-1974, 1977-1978: Copper-nickel clad (91.67% copper core wearing an 8.33% nickel jacket)
• 1975-1976 Bicentennials: Same clad composition but featuring stunning Revolutionary War drummer reverses
• Silver Issues: 40% silver-clad treasures made exclusively for collectors (all mint marks except elusive 1973)

Our forum discussion rightly spotlights the crown jewels needing extra protection—the 1972 Type 1 (bold high relief) and Type 3 (modified low relief) reverses, plus those tantalizing Bicentennial narrow letter varieties. These transitional strikes aren’t just coins—they’re minting history in your palm!

The Toning Dilemma: Patina vs. Damage

Natural toning occurs when metals dance with their environment over time. On copper-nickel IKEs, this chemical waltz creates:

• Rainbow iridescence (coveted when evenly distributed)
• Warm gold and bronze accents
• Steely blue rims that frame the design

DO: Cherish attractive natural toning in archival-quality holders
DON’T: Try “improving” nature’s artwork—you’ll murder its eye appeal

Those 1972 Type 1 coins discussed in the forum likely developed glorious golden patinas that accentuate their dramatic Earth-facing eagle. Never strip away this earned character!

Oxidation: The Silent Killer of Clad Coinage

While silver develops elegant toning, copper-nickel clad compositions face more destructive threats:

• Angry red spots screaming “copper corrosion!”
• Chalky white powder—the telltale cry of nickel oxidation
• Menacing black stains creeping from reeded edges

These destructive processes accelerate like wildfire in humidity. The 1977-D coins dominating our forum member’s find? They’re especially vulnerable after decades trapped in moisture-laden bank rolls.

Battle Plan for Preservation

1. Maintain 35-40% humidity like your coins’ life depends on it (because it does!)
2. Deploy silica gel soldiers in your storage trenches
3. Never entomb coins in plastic without climate controls

The PVC Menace: How Plastic Poisons Coin Surfaces

Cheap flips and albums containing polyvinyl chloride (PVC) emit acid gas that:

• Etches permanent microscopic scars
• Leaves sticky green “crime scene” residue
• Steals original luster through irreversible hazing

The original poster’s instinct to rescue six nicer coins was brilliant—they narrowly escaped PVC’s destructive embrace. For long-term survival:

Your Arsenal:
– Mylar flips (the numismatic gold standard)
– Acid-free cardboard fortresses
– PVC-free plastic tubes

Coin Kryptonite:
– Vinyl albums masquerading as “collector friendly”
– Rubber bands (just don’t!)
– Budget “starter kits” that destroy collectibility

Proper Holders for IKE Dollars

These 38.1mm giants demand specialized housing:

• Temporary Storage: Saflip Mylar flips (snug 38mm size)
• Showcase Display: Lighthouse Quadrum capsules (Q38 size)
• Bulk Protection: Guardhouse tubes (38mm diameter)

For those special finds like the 1972 Type 1s, I insist on individual capsules with inert gaskets. And please—banish foam-ring holders to the numismatic underworld where they belong!

The Cleaning Question: Why You Should Almost Always Say No

Every conservatory wall should display photos of cleaning disasters. I recently mourned a 1971-P Ike stripped of 90% numismatic value by baking soda scrubbing. Remember:

• Dipping murders original luster
• Polishing creates microscopic canyons
• Chemicals rewrite metal composition

When cleaning MIGHT be permissible:
– Active PVC damage (consult a pro first!)
– Storage residues (remove gently with cotton gloves only)

For the 74 circulated coins returning to circulation? A quick soapy bath won’t harm their minimal collectibility. But those six keeper coins? Don’t even breathe on them wrong!

Long-Term Storage Solutions

Follow this sacred protocol for generational preservation:

1. Stage 1: Mylar flip inspection under proper lighting
2. Stage 2: 48-hour silica gel stabilization
3. Stage 3: Archival capsule entombment
4. Stage 4: Climate-controlled sanctuary (65°F/18°C ideal)

For bulk storage of workhorses like 1977-D coins, Intercept Shield tubes work wonders—their polymer tech neutralizes corrosive gases like a force field!

Collectibility and Value Preservation

While most circulated Ikes carry modest premiums, exceptional specimens like:

• 1972 Type 1 high relief (the holy grail!)
• 1973 no-mintmark phantom
• Bicentennial narrow letter rare varieties

Can command impressive sums in mint condition. Proper conservation preserves grading options and protects against future environmental assaults.

Remember—every coin in that bank roll whispers 1970s economic history. Whether it’s a humble 1978-D destined for coffee shop adventures or a pristine 1972 Type 1 screaming for grading submission, these artifacts deserve preservation with passion. As our forum member discovered, the true reward lies in the hunt’s thrill and the pride of preserving history—one carefully shielded coin at a time.
