The Conservationist’s Guide to Preserving Lincoln Cents Before 1982

Understanding the Historical Value

I’ve seen too many valuable pieces ruined by improper cleaning or storage. Here is how to keep this safe for the next generation.

Lincoln cents minted before 1982 represent a unique period in American coinage history. These copper-based coins contain approximately 95% copper content, giving them inherent metallic value beyond their face denomination. However, their preservation requires understanding the delicate balance between maintaining historical integrity and preventing deterioration.

The Dangers of Improper Storage

Many collectors unknowingly damage their Lincoln cents through improper storage methods. The most common culprit is polyvinyl chloride (PVC), a chemical found in many inexpensive coin holders and flips. Over time, PVC leaches out and creates a greenish, sticky residue that permanently damages the coin’s surface.

Temperature and humidity fluctuations also pose significant threats. Coins stored in garages, attics, or basements are particularly vulnerable to toning and oxidation. The garage photo that frequently circulates online shows exactly what happens when coins are stored without environmental controls – rows of garbage cans filled with pennies developing various stages of corrosion.

Proper Storage Solutions

For long-term preservation, I recommend using archival-quality holders made from inert materials like Mylar or polyethylene. These materials won’t react with the copper content and will protect against environmental factors. For bulk storage, consider using airtight containers with silica gel packets to control moisture levels.

Temperature-controlled environments are ideal, though not always practical. If you must store coins in less-than-ideal conditions, rotate your storage containers periodically and inspect them regularly for signs of deterioration.

To Clean or Not to Clean

This is perhaps the most controversial topic in coin preservation. My professional recommendation is simple: don’t clean your coins unless absolutely necessary. Cleaning, even when done carefully, can remove the natural patina that develops over time and significantly reduce a coin’s numismatic value to collectors.

If you must clean a coin due to severe contamination or corrosion, use only distilled water and mild, non-abrasive soap. Never use commercial cleaning products, vinegar, or any acidic solutions. After cleaning, ensure the coin is completely dry before returning it to storage.

Understanding Toning and Oxidation

Natural toning on copper coins is not damage – it’s a protective layer that develops over time. The rainbow hues that appear on well-preserved copper coins are actually prized by many collectors. However, uneven toning or spots can indicate environmental damage and should be monitored.

Oxidation appears as green or blue deposits on the coin’s surface. While some oxidation is normal for copper, heavy deposits suggest improper storage conditions. Light surface oxidation can sometimes be carefully removed, but deep oxidation often permanently damages the coin.

Investment Considerations

While the debate continues about whether pre-1982 Lincoln cents are worth saving for their metallic content, I approach this from a preservation standpoint rather than an investment one. The current ban on melting these coins makes their immediate monetary value limited, but their historical significance remains intact.

If you’re collecting these coins, focus on quality preservation rather than quantity. A small collection of well-preserved specimens will maintain its value and historical importance far better than a large collection of deteriorating coins.

Best Practices for Long-Term Preservation

Document your collection with photographs and written descriptions. This not only helps track your collection’s growth but also provides valuable information for future owners or heirs. Store documentation separately from the coins themselves to prevent damage in case of environmental issues.

Regularly inspect your collection for signs of deterioration. Early detection of problems like PVC damage or environmental corrosion can prevent more serious damage. Handle coins only by their edges and consider using cotton gloves for particularly valuable specimens.

Conclusion

The decision to save pre-1982 Lincoln cents ultimately depends on your collecting goals and available resources. However, if you do choose to preserve these coins, proper storage and handling techniques are essential. Remember that you’re not just saving metal – you’re preserving a piece of American history that deserves careful stewardship for future generations.

Whether you’re a serious collector or a casual saver, the principles of proper preservation remain the same: protect from environmental damage, avoid cleaning unless absolutely necessary, and store in archival-quality materials. By following these guidelines, you can ensure that your Lincoln cents remain in the best possible condition for years to come.
