Preserving the 1907 Saint-Gaudens High Relief Double Eagle: A Conservationist’s Guide

The Importance of Proper Preservation

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 1907 High Relief Saint-Gaudens Double Eagle

The 1907 Saint-Gaudens High Relief Double Eagle represents one of the most beautiful and significant coins in American numismatic history. Designed by famed sculptor Augustus Saint-Gaudens at the request of President Theodore Roosevelt, this coin marked a turning point in U.S. coinage design. The high relief version was struck in extremely limited quantities – only 11,250 were produced before the design was modified to a lower relief for practical striking purposes.

Among these, only 17 examples have been certified as “Specimen” by PCGS, making them exceptionally rare and valuable. The coin in question, graded Specimen-61, is one of these ultra-rare pieces that will be offered at auction. The specimen designation indicates these coins were specially struck with care for collectors, featuring sharper details and superior surfaces compared to regular circulation strikes.

Common Preservation Challenges

Understanding Toning and Oxidation

Gold coins like the Saint-Gaudens double eagle are generally resistant to toning and oxidation due to gold’s noble metal properties. However, the alloy used in these coins (90% gold, 10% copper) means that copper can potentially oxidize over time, especially if exposed to environmental contaminants. The reddish hue visible on some high relief specimens often comes from the natural copper content in the alloy rather than harmful oxidation.

Proper storage in a controlled environment with stable temperature and humidity levels will prevent any unwanted chemical reactions. The ideal conditions are temperatures between 60-70°F with relative humidity below 50%. Avoid storing coins in basements, attics, or areas prone to temperature fluctuations.

PVC Damage: The Silent Killer

Polyvinyl chloride (PVC) is one of the most destructive substances for coin preservation. Many older coin holders and flips contained PVC, which can leach out over time and create a greenish, slimy residue that permanently damages the coin’s surface. The 1907 high relief specimen in question appears to be in a modern PCGS holder, which is PVC-free and inert, providing excellent long-term protection.

If you have coins in older holders, examine them carefully for any signs of PVC damage – a greenish tint on the holder or coin surface is a warning sign. Immediately transfer any affected coins to proper archival-quality holders.

The Rim Condition Question

Several forum members noted that the rim of this particular specimen appears “wobbly” or not perfectly round. This is actually characteristic of the high relief design and the striking process used in 1907. The extremely high relief required multiple strikes to fully bring up the design, and the metal flow during striking could result in slightly irregular rims.

Additionally, the Specimen-61 grade suggests this coin has some marks or imperfections, which could include rim nicks or irregularities. These are original characteristics rather than damage from improper storage, and attempting to “correct” them would only decrease the coin’s value and historical integrity.

Proper Storage Solutions

Choosing the Right Holder

For a coin of this caliber and value, a professional grading service holder like PCGS is ideal. These holders are made from inert materials that won’t react with the coin over time. The airtight seal also protects against environmental contaminants, humidity, and physical damage.

For coins you’re holding in your own collection, consider these options ranked by protection level:

• Professional grading service holders (PCGS, NGC, etc.)
• Air-tite holders with foam rings
• Acid-free cardboard 2×2 holders
• Archival-quality flips (non-PVC)

Environmental Considerations

Even with proper holders, environmental factors play a crucial role. Store your collection in a cool, dry place away from direct sunlight. UV light can accelerate chemical reactions and potentially affect the coin’s surfaces over decades. Consider using silica gel packets in your storage area to control humidity, but ensure they don’t directly contact the coins.

Avoid areas with volatile organic compounds (VOCs) such as freshly painted rooms, areas with cleaning supplies, or spaces near copiers and printers, which can release chemicals that might affect metal surfaces.

To Clean or Not to Clean: The Golden Rule

“Never clean a valuable coin unless you are a professional conservationist.”

This cannot be overstated. The natural patina and toning that develops on coins over time is often desirable to collectors and can actually increase a coin’s value. The 1907 high relief specimens, in particular, should never be cleaned or polished.

Cleaning attempts often result in:

• Micro-scratches that become visible under magnification
• Removal of the natural patina that collectors value
• Potential chemical reactions that can damage the metal
• Significant decrease in market value – sometimes by 50% or more

If a coin is genuinely dirty with debris or substances that could cause long-term damage, consult a professional conservationist who specializes in numismatic preservation. They have the proper tools, techniques, and chemicals to safely clean coins without damaging their surfaces.

Long-term Preservation Strategy

Documentation and Insurance

For coins of this value and rarity, proper documentation is essential. Keep detailed records including:

• Original purchase receipts and provenance
• Grading documentation and certification numbers
• High-quality photographs documenting the coin’s condition
• Appraisals from qualified numismatists

Ensure your valuable collection is properly insured through a policy that specifically covers numismatic items. Standard homeowners insurance often doesn’t provide adequate coverage for rare coins.

Regular Condition Checks

While the coin should remain in its holder, periodically examine the holder itself for any signs of damage, clouding, or deterioration. The holder is your first line of defense, and any compromise to its integrity could expose the coin to environmental risks.

Handle holders only by their edges, and never open a professionally graded holder. The holder itself is part of the coin’s authentication and provenance.

Conclusion: Preserving History for Future Generations

The 1907 Saint-Gaudens High Relief Double Eagle represents more than just a valuable coin – it’s a piece of American art and history. With only 17 Specimen examples known to exist, each one tells a story of a pivotal moment in numismatic design and American coinage.

By following proper preservation techniques – using appropriate holders, controlling environmental factors, avoiding cleaning, and maintaining proper documentation – you ensure that this magnificent coin can be appreciated by future generations of collectors and historians. The slight rim irregularities noted by forum members are part of this coin’s character and history, not flaws to be corrected.

Remember, the goal of preservation is not to make a coin look “perfect” but to maintain its historical integrity and prevent actual damage. When in doubt about any preservation decision, consult with professional numismatists or conservationists who can provide expert guidance tailored to your specific coin and situation.

This extraordinary specimen represents the pinnacle of American coin design, and with proper care, it will continue to inspire and educate for centuries to come.
