Preserving Your Oblong Penny Collection: Expert Conservation Tips

The Growing Value of Elongated Coin Collections

As a dedicated conservationist, I’ve witnessed countless collections lose their numismatic value and historical significance due to improper storage and handling. Elongated coins, whether you call them “oblong” or “elongated,” represent a unique intersection of numismatics and Americana that deserves careful preservation.

Understanding the Preservation Challenge

These flattened souvenirs face several preservation challenges that differ from standard coins. The elongation process itself creates stress points in the metal, making them more susceptible to certain types of damage. Additionally, the designs pressed into these coins can trap contaminants, leading to accelerated deterioration.

Common Threats to Elongated Coins

• Environmental factors: Humidity and temperature fluctuations can accelerate corrosion
• PVC damage: Many common storage materials contain polyvinyl chloride that can leach harmful chemicals
• Physical stress: The elongated shape makes these coins more prone to bending or cracking
• Surface contamination: Oils from handling and airborne pollutants can cause discoloration

Proper Storage Solutions

The debate about cleaning elongated coins often overlooks the more critical issue of proper storage. Here’s how to protect your collection:

Choosing the Right Holders

“The key to preserving elongated coins isn’t about making them look new again, but about preventing further deterioration while maintaining their historical character.”

Avoid PVC-based holders at all costs. Instead, opt for:

• Archival-quality Mylar flips: These provide excellent protection without chemical interaction
• Acid-free paper envelopes: Ideal for bulk storage of less valuable pieces
• Custom-cut foam inserts: Perfect for displaying your collection while preventing movement

Climate Control Essentials

Maintaining proper environmental conditions is crucial for long-term preservation:

Temperature and Humidity

• Keep storage area between 65-70°F (18-21°C)
• Maintain relative humidity at 45-55%
• Use silica gel packets to control moisture in storage containers

To Clean or Not to Clean?

This question generates heated debate among collectors. As a conservationist, my stance is clear: minimal intervention is best.

When Cleaning Might Be Necessary

If cleaning is absolutely necessary due to harmful deposits:

1. Use only distilled water and a soft brush
2. Never use abrasive materials or harsh chemicals
3. Dry thoroughly with compressed air (never rub)
4. Consider professional conservation for valuable pieces

Understanding Toning and Oxidation

The natural toning that develops on elongated coins can actually enhance their character and value. However, distinguishing between desirable toning and harmful oxidation is crucial:

Desirable Toning

• Even coloration across the surface
• Subtle color variations that enhance design details
• Natural patina that develops over time

Harmful Oxidation

• Green or black spots indicating active corrosion
• Uneven discoloration suggesting chemical reactions
• Surface pitting or flaking

Handling Best Practices

Even with perfect storage, improper handling can undo all your preservation efforts. Follow these guidelines:

Safe Handling Techniques

• Always hold coins by their edges
• Wear clean cotton gloves when handling valuable pieces
• Avoid touching the design areas where possible
• Never stack elongated coins directly on top of each other

Documentation and Organization

Proper documentation is often overlooked but essential for preservation:

Record Keeping

• Photograph each piece with high-resolution images
• Document the date and location of acquisition
• Note any special characteristics or historical significance
• Keep a separate log of storage conditions and any conservation work

Long-term Preservation Strategy

Preserving your elongated coin collection is about more than just physical protection. It’s about maintaining the historical narrative these pieces represent.

Regular Maintenance

Schedule periodic checks of your collection:

• Inspect for signs of deterioration every 6-12 months
• Check storage materials for signs of degradation
• Update documentation as needed
• Rotate displayed pieces to prevent light damage

The Future of Elongated Coin Collecting

With the potential discontinuation of the cent, elongated coins may become even more historically significant. Proper preservation ensures these pieces remain valuable both monetarily and historically for future generations.

Investment Considerations

As the article mentions, certain elongated coins have sold for hundreds or even thousands of dollars. Proper preservation directly impacts value:

• Well-preserved pieces command premium prices
• Historical significance increases with proper documentation
• Rare designs become more valuable when preserved in excellent condition

Conclusion

Your elongated coin collection represents more than just souvenirs—they’re pieces of American history. By following these conservation principles, you’re not just protecting your investment; you’re preserving a tangible connection to the past for future generations to appreciate and study.

Remember, the goal isn’t to make these coins look new, but to maintain their character while preventing further deterioration. With proper care and attention, your collection can remain a source of pride and historical significance for decades to come.
