Preserving Your British Victorian and Edwardian Coinage: Expert Conservation Tips for 1871 Half Penny through 1902 Shilling

Introduction: The Conservationist’s Perspective

Throughout my years in numismatics, I’ve witnessed too many irreplaceable pieces ruined by improper cleaning or storage. Here’s how to protect your collection for future generations.

Understanding the Historical Context

This remarkable collection spans a pivotal era in British numismatics, from the early Victorian period through the Edwardian age. These coins represent far more than monetary value—they capture the essence of British history, from Queen Victoria’s long reign through Edward VII’s brief but impactful rule.

The specific coins include:

• 1871 Half Penny – A challenging date in Mint State condition
• 1838 Shilling – Early Victorian silver with distinctive high-relief characteristics
• 1850 Three Pence – Silver coin with exceptional original surfaces
• 1889 Double Florin – An intriguing denomination that failed to gain widespread acceptance
• 1902 Shilling – A common date with potential for exceptional gem specimens
• 1812 Bank Token – A Georgian-era piece showing remarkable preservation

The Critical Importance of Original Surfaces

Several collectors noted these coins “all look original and great, and generally under-graded by a grade.” This observation highlights a fundamental principle in coin conservation: original surfaces are paramount.

“Coins graded at a certain level are not equal – some will look better than others.”

This subjective element in grading underscores why preservation matters so much. A coin with original surfaces and natural toning will always command a premium over cleaned specimens, regardless of technical grade.

Toning: Friend or Foe?

Toning on silver coins like the 1838 Shilling and 1850 Three Pence can either enhance or detract from a coin’s appeal, depending on how it developed. Natural toning, which occurs gradually over decades, often creates beautiful rainbow or amber hues that enhance eye appeal while protecting the underlying metal.

However, artificial toning or toning caused by environmental factors can be problematic. The 1902 Shilling discussion mentioned “hand oil exposure with minimal oxidation,” a common issue where human contact accelerates toning in undesirable patterns.

Types of Toning to Recognize

• Natural Toning: Develops slowly, creating attractive rainbow or amber hues that enhance eye appeal
• Environmental Toning: Caused by storage conditions, often appears uneven or splotchy
• Artificial Toning: Chemically induced, frequently looks unnatural and can mask imperfections

Oxidation: The Silent Destroyer

Oxidation affects copper coins like the 1871 Half Penny differently than silver coins. The discussion mentioned a grade of “63 BN” (Brown Numismatic), indicating significant oxidation on what was likely originally a red copper coin.

For copper coins, oxidation follows a predictable progression:

1. RD (Red): Original mint luster, most desirable for collectors
2. RB (Red-Brown): Partial oxidation, still valuable to collectors
3. BN (Brown): Full oxidation, least valuable but still collectible

The 1871 Half Penny “misses RB, but still within my estimated grade range,” suggesting it has progressed beyond the red-brown stage but retains enough detail and eye appeal for a respectable grade.

PVC Damage: The Hidden Threat

While not explicitly mentioned in the discussion, PVC (Polyvinyl Chloride) damage represents a critical concern for coin collectors. Many older coin holders and flips contained PVC, which can leach out over time and cause irreversible green slime damage to coins.

Signs of PVC damage include:

• Greenish residue on coin surfaces
• Cloudy or hazy appearance
• Sticky or tacky feel to the holder

Modern archival-quality holders are PVC-free and should be used for long-term storage of valuable pieces like the 1838 Shilling or 1902 Shilling.

Proper Holders: The First Line of Defense

The discussion mentions PCGS grades, indicating these coins have been professionally encapsulated. Third-party grading and encapsulation provides excellent protection, but proper storage of the holders themselves is equally important.

Recommended Storage Solutions

• Archival Flip Boxes: For ungraded coins awaiting submission
• Temperature-Controlled Environments: Ideal humidity is 45-55%, temperature 65-70°F
• Away from Direct Light: UV light accelerates toning and can fade details
• Individual Capsules: For high-value pieces like potential gem specimens

To Clean or Not to Clean: The Eternal Debate

Based on the discussion, these coins were valued precisely because they appeared “original.” This reinforces the fundamental rule: never clean valuable coins.

Cleaning, even when done gently, almost always reduces a coin’s value. Professional graders can detect cleaning, and coins with original surfaces command premiums. The 1812 Bank Token graded AU58, suggesting it retained original surfaces despite its age.

If Cleaning is Absolutely Necessary

For coins with significant dirt or PVC residue (not original toning), professional conservation may be warranted. This should only be done by experts using proper techniques like:

• Distilled water rinses
• Non-abrasive, pH-neutral solutions
• Specialized conservation tools

Grading Considerations for British Coinage

The discussion provides valuable insights into grading British coins:

“One problem with the higher relief Vick silvers is that the highest relief hair is not fully struck up and so with even minimal cabinet friction (or equivalent) smacks the coins at the TPGs.”

This observation about the 1838 Shilling highlights the importance of understanding strike characteristics for specific coin types. British Victorian silver often shows weakness at the highest points, which can affect grades even on otherwise well-preserved specimens.

Specific Conservation Recommendations by Coin Type

Copper Coins (1871 Half Penny)

Copper is particularly susceptible to environmental damage. Store in airtight holders with silica gel packets to control humidity. Avoid touching copper coins directly, as oils from skin accelerate oxidation.

Silver Coins (1838 Shilling, 1850 Three Pence, 1902 Shilling)

Silver can develop tarnish and toning. While some toning is desirable, prevent excessive tarnish by storing in tarnish-intercepting cloths or holders. The 1889 Double Florin “missed expectations” partly due to toning issues.

Copper-Nickel and Other Alloys (1812 Bank Token)

These alloys are generally more stable but can still develop patina. The 1812 Bank Token graded AU58, suggesting good preservation of its original surfaces.

Environmental Factors to Control

Proper storage goes beyond just holders. Consider these environmental factors:

• Humidity: High humidity accelerates toning and can cause spotting
• Temperature Fluctuations: Cause expansion and contraction, potentially loosening holders
• Air Quality: Pollutants can accelerate toning and corrosion
• Light Exposure: UV light can fade details and accelerate chemical reactions

Long-Term Preservation Strategy

For a collection spanning from 1812 to 1902, a comprehensive preservation strategy is essential:

1. Document current condition with high-quality photographs
2. Store in archival-quality holders appropriate to each coin type
3. Maintain detailed records of storage conditions and any conservation work
4. Regularly inspect for signs of deterioration
5. Consider professional conservation for valuable pieces showing early signs of damage

Conclusion: Preserving History for Future Generations

The discussion of these British Victorian and Edwardian coins reveals a fundamental truth about numismatics: preservation is as much about protecting history as it is about maintaining value. The 1838 Shilling, 1871 Half Penny, and other pieces in this collection represent tangible connections to Britain’s past.

By understanding the specific conservation needs of different coin types, recognizing the value of original surfaces, and implementing proper storage techniques, collectors can ensure these historical artifacts survive for future generations to study and appreciate. The subjective nature of grading, as noted in the discussion, only emphasizes how crucial proper preservation is—a well-preserved coin with original surfaces will always be more desirable than one that has been compromised, regardless of technical grade.

Remember: when in doubt about cleaning or conservation, consult a professional. The cost of expert advice is minimal compared to the potential loss in value from improper handling. Your coins are not just investments; they are pieces of history that deserve careful preservation.
