The Silver & Gold Content of Collecting French 20-franc gold coins Explained

Introduction: Melt Value vs. Numismatic Value

Sometimes the metal inside is worth more than the face value. Let’s break down the melt value versus the collector value.

Understanding the French 20-Franc Gold Coin

The French 20-franc gold coin, often called the “Napoleon” or “Rooster,” represents one of the most iconic bullion coins in European history. These coins contain approximately 0.1867 troy ounces of pure gold (5.8 grams) with a total weight of 6.45 grams and a diameter of 21.0 mm. The purity is 90% gold (21.6 karats), with the remaining 10% being copper for durability.

Historical Significance

The 20-franc series spans multiple French regimes, making it a fascinating historical artifact. From the First Republic through the Third Republic, each coin tells a story of France’s political evolution. The series includes:

• First Republic (1793-1804)
• First Empire (Napoleon I, 1804-1814)
• First Restoration (1814-1815)
• Hundred Days (Napoleon’s brief return, 1815)
• Second Restoration (1815-1830)
• July Monarchy (1830-1848)
• Second Republic (1848-1852)
• Second Empire (Napoleon III, 1852-1870)
• Third Republic (1870-1898)

Purity and Weight Specifications

Each 20-franc gold coin contains:

• Total weight: 6.45 grams
• Gold content: 5.806 grams (0.1867 troy ounces)
• Purity: 90% gold, 10% copper alloy
• Diameter: 21.0 mm
• Thickness: Approximately 1.3 mm

Spot Price Correlation

The melt value of these coins tracks closely with the spot price of gold. When gold trades at $3,500 per ounce, the melt value of a 20-franc coin is approximately:

$3,500 × 0.1867 = $653.45

This calculation excludes any numismatic premium, which can range from 2% to over 100% depending on rarity, condition, and historical significance.

Stacking Strategy for Bullion Investors

Building a Type Set

For investors looking to combine bullion value with numismatic interest, building a type set of French 20-franc coins offers several advantages:

1. Diversification: Each coin represents a different historical period
2. Recognition: These coins are widely recognized and liquid
3. Premium potential: Certain dates and conditions carry significant numismatic premiums

Key Dates and Rarities

While most 20-franc coins trade close to their melt value, certain dates command substantial premiums:

• Hundred Days (1815): Extremely rare and valuable
• First Republic issues: Particularly those from 1793-1795
• High-grade specimens: MS-62 and above for common dates

Avoiding Restrikes

Many “Rooster” coins dated 1907-1914 are actually restrikes produced decades later. While restrikes contain the same gold content and trade at similar bullion prices, collectors often prefer original strikes. The NGC census reports show that coins dated 1906 and earlier are generally original strikes.

Authentication and Identification

Edge Lettering

One distinctive feature of French 20-franc gold coins is the edge lettering. Most issues feature “DIEU PROTEGE LA FRANCE” (God Protects France), though some earlier Republican issues feature “LIBERTE EGALITE FRATERNITE.”

Mint Marks

French coins bear various mint marks indicating their origin:

• A: Paris Mint
• K: Bordeaux
• E: Strasbourg
• W: Lille

Designer Signatures

Many coins feature designer signatures, most commonly “TIOLIER” for the portrait of Louis-Philippe I.

Market Analysis and Pricing

Current Market Conditions

As of recent trading, French 20-franc gold coins typically sell for 2-5% above their melt value in circulated condition. Premiums increase significantly for:

• Uncirculated specimens (BU)
• Rare dates and mints
• High-grade certified coins

Price Comparison: US vs. Europe

Interestingly, prices for these coins are often lower in the United States than in France, despite being French coins. This price differential may reflect lower demand in the US market and different collecting traditions.

Investment Considerations

Pros of Investing in French 20-Franc Coins

• Intrinsic Value: Contains nearly 0.19 troy ounces of gold
• Liquidity: Widely recognized and easy to sell
• Historical Premium: Potential for numismatic appreciation
• Divisibility: Smaller than 1-ounce bullion coins

Cons and Risks

• Premium Over Spot: Pays more than generic bullion
• Authentication: Need to verify authenticity, especially for rare dates
• Market Knowledge: Requires understanding of both bullion and numismatic markets

Conclusion: A Balanced Approach

The French 20-franc gold coin represents an excellent option for investors seeking to combine bullion value with historical interest. While the melt value provides a solid floor, the numismatic potential offers upside for those willing to research and collect specific dates and conditions.

For stackers focused purely on metal content, these coins offer an attractive alternative to modern bullion coins, often trading at lower premiums than government-minted bullion. For collectors, the rich history and variety of designs make building a type set both educational and potentially rewarding.

Whether you’re a bullion investor looking for recognizable gold coins or a collector interested in French history, the 20-franc series deserves serious consideration. Just remember to verify authenticity, understand the difference between original strikes and restrikes, and be prepared for the premiums that rare dates and high grades can command.
