Preserving Your 1936-1942 Proof Lincoln Cent Collection: A Conservationist’s Guide

Introduction: The Importance of Proper Preservation

As a conservationist who has witnessed countless valuable coins deteriorate due to improper handling and storage, I cannot stress enough the importance of proper preservation techniques. Your new venture into collecting Proof Lincoln cents from 1936-1942 represents not just a financial investment, but a piece of American numismatic history that deserves protection for future generations.

Understanding Your Collection’s Historical Significance

The 1936-1942 Proof Lincoln cents represent a pivotal era in American coinage. These coins were produced during a time of significant economic and political change, just before and during World War II. The proof coins from this period were struck with exceptional care, featuring deep mirror fields and frosted devices that create the distinctive cameo effect that collectors prize today.

Your decision to focus on PCGS and CAC-certified Proof 66 Red specimens demonstrates an appreciation for quality and authenticity. These coins, particularly when certified by both PCGS and CAC, represent the pinnacle of preservation for this era. The “Red” designation indicates that these coins have retained their original mint luster and have not toned to brown or red-brown, making them especially desirable to collectors.

The Science of Toning and Oxidation

One of the most critical aspects of preserving your Proof Lincoln cents is understanding the natural processes of toning and oxidation. Even in a Proof 66 Red condition, these coins are susceptible to environmental factors that can accelerate toning or cause undesirable oxidation.

Copper, the primary metal in Lincoln cents, naturally reacts with sulfur compounds in the air, leading to the formation of copper sulfide. This reaction creates the beautiful rainbow toning that some collectors prize, but it can also lead to unsightly spots or a dulling of the coin’s surface if not properly controlled.

The key to preventing unwanted toning is controlling the coin’s environment. Factors such as humidity, temperature, and exposure to pollutants all play a role in how quickly a coin will tone. Ideally, your coins should be stored in an environment with relative humidity below 50% and a stable temperature between 60-70 degrees Fahrenheit.

Understanding PVC Damage and Prevention

Polyvinyl chloride (PVC) damage is one of the most common and destructive forms of damage that can affect your coin collection. PVC was once commonly used in coin flips and other storage materials, but it can leach out over time and create a greenish, slimy residue on coins that is nearly impossible to remove without damaging the coin’s surface.

Fortunately, modern coin holders are made from inert materials that do not contain PVC. However, if you have older coins in your collection that were previously stored in PVC-containing materials, it’s essential to have them professionally conserved to remove any residue before transferring them to proper holders.

Proper Holders and Storage Solutions

For your Proof Lincoln cents, the holders they come in from PCGS and CAC are already excellent for long-term preservation. These holders are made from high-quality, inert plastics that will not react with your coins. However, how you store these holders is equally important.

Consider investing in a safety deposit box or a home safe that provides both physical security and environmental control. Avoid storing your coins in basements or attics where temperature and humidity fluctuations are common. Instead, choose a location in your home that maintains a relatively constant environment.

For display purposes, consider using a coin cabinet with individual drawers lined with acid-free, sulfur-free materials. This will protect your coins from dust and handling while allowing you to enjoy your collection.

To Clean or Not to Clean: The Conservationist’s Perspective

One of the most controversial topics in coin collecting is whether to clean coins. As a conservationist, my position is clear: never clean a coin unless it is absolutely necessary and done by a professional conservator.

The coins you have acquired in Proof 66 Red condition are already in exceptional state, and any attempt to clean them could potentially damage the delicate surfaces and reduce their value. Even gentle cleaning can remove microscopic layers of metal and alter the coin’s original surface characteristics.

If you notice any spots or discoloration on your coins, resist the urge to clean them yourself. Instead, consult with a professional conservation service that specializes in numismatics. They have the expertise and equipment to address issues without compromising the coin’s integrity.

Handling Your Collection with Care

Proper handling is just as important as proper storage when it comes to preserving your collection. Always handle your coins by the edges, never touching the flat surfaces with your fingers. The oils and acids on your skin can cause spots and discoloration over time.

Consider wearing cotton gloves when handling your coins, and always work on a soft, clean surface in case a coin is accidentally dropped. Never speak over your coins, as tiny droplets of saliva can cause spots that are difficult to remove.

Monitoring and Maintaining Your Collection

Regular monitoring of your collection is essential for long-term preservation. Periodically inspect your coins for any signs of toning, spotting, or other changes. Check the seals on your holders to ensure they remain airtight, and replace any holders that show signs of wear or damage.

Keep detailed records of your collection, including photographs and condition reports. This documentation will not only help you track the condition of your coins over time but will also be valuable for insurance purposes and potential future sales.

Insurance and Security Considerations

Given the value of your PCGS and CAC-certified Proof Lincoln cents, proper insurance coverage is essential. Speak with your insurance provider about adding a rider to your homeowner’s policy or obtaining a separate collectibles policy that specifically covers your coins.

Ensure that your storage location is secure and that you have taken appropriate measures to protect your collection from theft. This might include a home safe, alarm system, or safety deposit box at your bank.

Conclusion: Preserving History for Future Generations

Your collection of 1936-1942 Proof Lincoln cents represents a significant investment in both financial and historical terms. By following proper preservation techniques, you are not just protecting your investment but also preserving a piece of American history for future generations to appreciate.

Remember that the goal of preservation is not to keep your coins in a vacuum, but to maintain their condition while allowing them to be appreciated and studied. With proper care and attention, your collection will continue to be a source of pride and enjoyment for many years to come.

Good luck with your new venture, and may your collection continue to grow in both size and significance!
