Preserving Peace: Protecting Your 1928 Peace Dollar from Damage and Alteration

Introduction: The Fragility of Historical Coins

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

Understanding the 1928 Peace Dollar

The 1928 Peace Dollar represents a pivotal moment in American numismatic history. Struck at the Philadelphia Mint (no mint mark), this coin was part of the final year of Peace Dollar production before a 35-year hiatus. The coin contains 90% silver and 10% copper, making it particularly susceptible to environmental damage and chemical reactions over time.

Historical Significance

The Peace Dollar series was created to commemorate the peace following World War I. The 1928 issue is particularly notable because it was struck during the height of the Great Depression when silver dollar production had essentially ceased. With a relatively low mintage of just over 360,000 pieces, the 1928 Peace Dollar is one of the key dates in the series.

The Dangers of Improper Handling

The forum discussion you’ve referenced highlights a critical issue in coin collecting: the prevalence of altered coins and the importance of proper preservation. When examining a potentially altered 1928-S Peace Dollar that’s been modified to appear as a 1928-P, we must consider the various ways improper handling and storage can damage these historical artifacts.

Toning and Oxidation

Silver coins naturally develop toning over time due to exposure to sulfur compounds in the air. This toning can range from subtle golden hues to vibrant rainbow colors and even deep charcoal patinas. While some collectors prize attractive toning, improper storage can lead to unsightly or damaging oxidation.

Proper storage in archival-quality holders with stable temperature and humidity levels can slow the toning process and preserve the coin’s original surfaces. Avoid storing coins in basements, attics, or areas with fluctuating environmental conditions.

PVC Damage: The Silent Killer

Polyvinyl chloride (PVC) is found in many common coin holders and flips. When PVC breaks down, it releases hydrochloric acid that can permanently damage coin surfaces, creating a distinctive greenish slime or etching pattern. Once PVC damage occurs, it’s irreversible and significantly reduces a coin’s value.

Always use PVC-free archival holders specifically designed for long-term coin storage. Look for products labeled “archival safe,” “acid-free,” or “PVC-free.”

Proper Storage Solutions

The discussion about a potentially altered coin underscores the importance of proper storage not just for preservation, but also for authentication purposes. Here are the best practices for storing your Peace Dollars:

Recommended Holders

For Peace Dollars, consider these storage options:

• Air-tite capsules: Provide excellent protection from environmental factors and handling
• Acid-free cardboard 2×2 holders with Mylar windows: Economical and safe for long-term storage
• Archival-quality coin albums: Allow for organized display while protecting edges and surfaces
• Safety deposit boxes: Offer stable temperature and humidity control

What to Avoid

Never store valuable coins in:

• Regular plastic flips containing PVC
• Paper envelopes or holders with acidic content
• Glass jars or containers that can trap moisture
• Areas with direct sunlight or extreme temperature changes

To Clean or Not to Clean: The Eternal Question

The forum discussion mentions a coin that appears to have been “harshly cleaned” to hide surface disturbances. This brings us to one of the most controversial topics in numismatics: coin cleaning.

The Case Against Cleaning

Professional numismatists and serious collectors almost universally advise against cleaning coins, especially valuable or historical pieces. Cleaning can:

• Remove the natural patina that develops over decades
• Create unnatural surfaces that are easily detected by experts
• Reduce the coin’s value by 50% or more
• Potentially damage the coin’s surface through abrasion or chemical reaction

The Peace Dollar in question appears to have been cleaned in an attempt to disguise alterations. This not only failed to solve the problem but likely created additional issues that further complicate authentication and reduce value.

Proper Conservation vs. Cleaning

There is a significant difference between cleaning and professional conservation. Conservation involves carefully removing harmful deposits or stabilization of deteriorating surfaces by trained professionals using reversible methods. If you believe your coin requires intervention, consult with a professional conservation service like those certified by the Professional Coin Grading Service (PCGS) or Numismatic Conservation Services (NCS).

Authentication and the Problem of Altered Coins

The forum discussion reveals multiple experts identifying signs of alteration on what appears to be a 1928-S Peace Dollar that has been modified to look like a 1928-P. This practice, while unethical, unfortunately exists in the numismatic marketplace.

Red Flags for Alteration

Based on the expert observations in the forum, watch for these signs of potential alteration:

• Stains or disturbances where a mint mark would typically be located
• Inconsistent surface texture or luster in specific areas
• Partial missing design elements (like the mentioned “partial missing ray”)
• Conveniently placed distortion or tooling marks
• Evidence of harsh cleaning that seems intended to hide alterations

Professional Authentication

For valuable coins, especially those with potential authentication issues, professional grading and authentication is essential. Third-party grading services like PCGS, NGC, ANACS, and ICG can:

• Authenticate the coin’s legitimacy
• Identify and note alterations or problems
• Provide a standardized grade that reflects the coin’s condition
• Encapsulate the coin in a tamper-evident holder

Even if a coin is authenticated as a particular variety, as one forum member noted, an altered coin will “always be a problem coin” that carries a stigma affecting its value and collectibility.

Preserving Value for Future Generations

The final comments in the forum discussion about potentially defacing a coin to prevent future confusion raise an important ethical question. While the intention to prevent fraud is admirable, defacing a coin destroys historical evidence and cultural heritage.

Ethical Preservation

Instead of defacement, consider these approaches:

• Document the coin thoroughly with high-resolution photographs
• Include detailed notes about the coin’s history and your suspicions
• Store the coin separately with clear labeling about its questionable status
• Consider donating questionable pieces to educational institutions for study

Every coin tells a story, even problematic ones. By preserving rather than destroying, we maintain valuable information about historical counterfeiting techniques, market pressures, and the evolution of collecting ethics.

Conclusion: The Responsibility of Preservation

The 1928 Peace Dollar represents not just monetary value but a tangible connection to America’s past. Whether you’re dealing with a pristine example or a problematic altered piece, your approach to storage and preservation has lasting consequences.

Remember these key principles:

1. Never clean valuable coins unless performed by conservation professionals
2. Use only archival-quality storage materials free from PVC and acids
3. Maintain stable environmental conditions for your collection
4. Seek professional authentication for valuable or questionable pieces
5. Document everything about your coins, including their history and any concerns

By following these guidelines, you not only protect your investment but also preserve these historical artifacts for future generations of collectors, historians, and enthusiasts who will continue to study and appreciate the rich legacy embodied in coins like the 1928 Peace Dollar.
