How to Properly Store and Preserve Your 1983-S Proof Lincoln Cent

Understanding Your 1983-S Proof Lincoln Cent

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

Historical Significance

The 1983-S Proof Lincoln Cent represents an interesting piece of American numismatic history. This coin comes from the San Francisco Mint, as indicated by the “S” mint mark, and was produced specifically for collectors as part of proof sets. Proof coins are struck multiple times with specially prepared dies and planchets, resulting in their distinctive mirror-like fields and frosted devices.

Identifying Key Markers

Your coin shows some concerning characteristics that require immediate attention. The images reveal what appears to be split plating on the obverse, where the copper plating has separated from the zinc core. This exposes the zinc underneath, which appears as white areas in your photographs. Additionally, there may be some strike doubling visible on the date and lettering, though this could also be die erosion doubling or simply reflections in the fields.

Preservation Challenges

The split plating is particularly problematic. When copper plating separates from the zinc core, it creates an entry point for environmental damage. The exposed zinc will begin to oxidize and deteriorate through a process called zinc rot. Over time, these white areas will likely turn black as the zinc corrodes, permanently damaging the coin’s appearance and structural integrity.

Proper Storage Solutions

To protect your 1983-S proof cent, you need to address several key preservation factors:

Temperature and Humidity Control

Store your coin in a cool, dry environment. Ideal conditions are between 60-70°F with relative humidity below 50%. Avoid areas prone to temperature fluctuations like attics, basements, or exterior walls.

Proper Holders

Use archival-quality holders specifically designed for coin storage. Avoid PVC-based holders, as PVC can leach chemicals that damage coins over time. Instead, opt for holders made from inert materials like polyester, polyethylene, or Mylar. For a proof coin, a capsule or flip that prevents contact with other coins is ideal.

Light Exposure

Keep your coin away from direct sunlight and strong artificial light. UV rays can accelerate toning and oxidation processes, particularly on already compromised surfaces.

To Clean or Not to Clean

This is perhaps the most critical question for your 1983-S proof cent. The answer is unequivocally: do not clean this coin. Cleaning can never improve a coin’s value and will almost certainly damage it further. The split plating areas are already compromised, and any cleaning attempt would likely remove more metal and create additional surface damage.

If you’re concerned about the appearance, professional conservation by a qualified expert might be an option, but this should only be considered for truly valuable pieces. Given the current condition and market value of your coin, conservation is likely not cost-effective.

Preventing Further Damage

The split plating on your coin is already allowing environmental factors to affect the exposed zinc. To prevent further deterioration:

• Handle the coin only by its edges, using clean, dry hands or cotton gloves
• Store it in an airtight container with a desiccant packet to control moisture
• Avoid touching or rubbing the affected areas
• Keep it separate from other coins to prevent contact damage

Understanding Toning and Oxidation

While toning can sometimes enhance a coin’s appearance, the oxidation occurring on your coin is destructive rather than aesthetic. The zinc rot will continue to progress unless the coin is properly protected. Unlike the desirable toning that can develop on copper or silver coins, zinc corrosion creates an unattractive, potentially unstable surface.

Long-term Preservation Strategy

For long-term preservation, consider these steps:

1. Place the coin in a new, high-quality holder if the current one shows any signs of wear or damage
2. Store it in a safety deposit box or home safe rather than a vulnerable location
3. Document the coin’s current condition with clear photographs
4. Consider having it authenticated and graded by a professional service if you believe it has significant value

Market Value Considerations

It’s worth noting that your 1983-S proof cent, while interesting, has limited market value. Proof coins from this era were produced in large quantities, and the split plating further reduces its appeal to collectors. However, proper preservation ensures that even common coins can be enjoyed by future generations.

Learning from This Experience

This coin serves as an excellent example of why proper storage and handling are crucial from the moment a coin enters your collection. Many collectors learn about preservation only after damaging valuable pieces. By understanding and implementing proper preservation techniques now, you’ll protect your entire collection for years to come.

Conclusion

Your 1983-S proof Lincoln cent, despite its current condition, represents an opportunity to practice proper numismatic preservation. By providing the right storage environment and handling it correctly, you can prevent further deterioration and maintain its current state. Remember, the goal of preservation isn’t always to improve a coin’s appearance, but to maintain its historical integrity and prevent additional damage. With proper care, this coin can remain a stable part of your collection for decades to come.
