Key Value Factors:
- Condition: Graded coins (MS64+) command significant premiums.
- Mint Mark: Paris (A), Strasbourg (BB), and other mints affect rarity.
- Metal Content: Gold coins contain .1867 oz (20 Francs) to .9330 oz (100 Francs) of .900 fine gold.
- Collector Demand: Historical significance drives numismatic value.
The year 1855 was significant, as France hosted the Exposition Universelle in Paris, showcasing its industrial might under Emperor Napoleon III. Coins from this year circulated widely as part of the Latin Monetary Union, making them both historical artifacts and investment-grade precious metals.
Unlike modern bullion, these coins carry numismatic value beyond their gold or silver content. A circulated 20 Francs gold coin contains about $517 in melt value (at recent prices), yet collectors pay anywhere from $510 to $15,275 depending on condition and rarity. You're not just buying metal—you're acquiring a piece of mid-19th century European history.

The 1855 Napoleon III Coin Family: Denominations and Designs
In 1855, Napoleon III's empire produced a range of coins, from bronze centimes for daily trade to magnificent gold pieces representing significant wealth. Designed by chief engraver Jean-Jacques Barre, these coins feature the Emperor's "Bare Head" portrait on the obverse (front) and an imperial eagle or wreath on the reverse (back). This design projected confidence and authority during an era when France was an economic powerhouse.
Many of these coins were part of the Latin Monetary Union, a precursor to the euro that allowed French francs to be used in Italy, Switzerland, Belgium, and Greece. This made them a truly international currency.
Bronze and Silver Coinage
The bronze and silver coins of 1855 were the workhorses of the French economy.
- 5 Centimes (Bronze): These small coins were heavily used, so finding one in pristine condition is rare. The 1855 napoleon iii coin value for these ranges from $1 for worn examples to $45 for well-preserved specimens. You can find more details at 5 Centimes - Napoleon III (France, 1853-1857).
- 10 Centimes (Bronze): Slightly larger, these coins can be worth a few dollars in circulated condition, but examples with sharp details or rare mint marks can exceed $100.
- 5 Francs (Silver): Containing 90% silver, these substantial coins have significant intrinsic value. The edge is inscribed with "DIEU PROTEGE LA FRANCE" (God Protect France). Recent prices place them at €125 to €140 in good condition.
The Famous Gold "Napoleons"
The gold "Napoleons" represent the pinnacle of 1855 French minting. Struck in 0.900 purity (90% gold, 10% copper), the alloy made them durable for circulation. To learn more about gold purity, see our guide on Understanding Karats and Purity in Gold.
- 10 Francs (Gold): The smallest gold coin, containing 0.0933 troy ounces of pure gold. They average around $260, with exceptional examples reaching $1,500.
- 20 Francs (Gold): The most iconic "Napoleon gold," containing 0.1867 troy ounces of pure gold. They average $510, but a pristine example sold for a record $15,275 at auction.
- 100 Francs (Gold): Magnificent coins containing 0.9330 troy ounces of pure gold. These were used for major transactions and typically trade for around $3,667 or more.

Key Factors That Determine Your 1855 Napoleon III Coin Value
The 1855 napoleon iii coin value is determined by three key factors: melt value, numismatic premium, and collector demand. Understanding these will reveal what your coin is truly worth.
1. Melt Value: This is the baseline worth of the coin's precious metal content. For a 20 Francs gold coin with 0.1867 troy ounces of gold, you can multiply that weight by the current spot price of gold to find its raw metal value. If gold is at $2,770 per ounce, the melt value is about $517.
2. Numismatic Premium: This is the value added by a coin's history, rarity, and condition. It's why most 1855 Napoleon III coins sell for more than their melt value. A circulated 20 Francs might sell for around its melt value, but a pristine specimen can fetch over $15,000. The entire value of bronze coins is numismatic, as their metal content is negligible.
3. Collector Demand: French gold coins are popular worldwide, and the 1855 date is especially desirable due to its connection to the Exposition Universelle in Paris. When demand for a specific date, mint mark, or high-grade coin is strong, prices rise. Historical gold coins also offer an advantage over modern bullion: as legal tender, they carry stiffer penalties for counterfeiting, providing an extra layer of fraud protection.
Before evaluating your coin, confirming its authenticity is crucial. Our guide on How to Tell If Gold Is Real provides practical tests you can do at home. In the sections below, we'll explore how condition, mint marks, and metal content specifically influence the final price.
1. Condition and Grading: From Worn to Pristine
Condition is the single most important factor driving 1855 napoleon iii coin value. Two identical 20 Francs gold coins can have vastly different prices—one selling for melt value, the other for over $15,000—based purely on their state of preservation.
A coin's grade reflects its level of wear. Collectors pay enormous premiums for coins that retain their original luster (the sheen from the minting process) and have sharp details with no wear.
The grading scale provides a universal language for condition:
- VF (Very Fine): Moderate wear, but major details are clear.
- XF (Extremely Fine): Light wear on the highest points of the design.
- AU (About Uncirculated): Only a trace of wear, with most mint luster remaining.
- MS (Mint State) or UNC (Uncirculated): No signs of circulation. These are graded on a scale from MS60 to MS70. An MS64 Napoleon III gold coin can be worth ten times a VF example.
Graders look for luster, wear, and any scratches or marks. For a definitive assessment, especially for valuable coins, third-party grading services like PCGS (Professional Coin Grading Service) and NGC (Numismatic Guaranty Corporation) are essential. They authenticate and grade the coin, then seal it in a protective holder (a "slab").
That record $15,275 sale for an 1855-A 20 Francs was for a high-grade Mint State coin certified by one of these services. Without professional grading, buyers lack confidence, and the coin would likely sell for a fraction of that price. You can find more information on coin values and grading at resources like Find more coin values at NumisMaster.com.
2. Mint Marks: The Alphabet of Rarity
After assessing condition, look for a small letter on your coin. This is the mint mark, and it indicates which facility produced it. Since production numbers varied between mints, this tiny detail can significantly impact the 1855 napoleon iii coin value.
The French Empire operated several mints in 1855, each with a unique letter code. On most Napoleon III coins, you'll find the mint mark on the reverse, often below the Imperial Eagle or within the wreath.
- A (Paris): As the primary mint, Paris had the highest production numbers. Coins with the "A" mint mark are the most common, but high-grade examples are still valuable due to strong collector demand.
- BB (Strasbourg): Production was generally lower in Strasbourg, so coins with the "BB" mint mark often carry a premium over their Paris counterparts.
- D (Lyon): Like Strasbourg, the Lyon mint had more limited production runs, making its coins scarcer and more valuable.
Other mints like Bordeaux (K) and Lille (W) also operated, but their 1855 output, especially for gold, was often scarce or non-existent.
Lower mintage numbers directly correlate to lower survival rates today. After 170 years of circulation, melting, and loss, a coin from a low-production mint is naturally rarer than one from a high-production facility. When researching your coin, always cross-reference its mint mark with known mintage figures. That small letter can be the difference between a nice coin and a true numismatic treasure.
3. Metal Content: The Foundation of Value
Every discussion of 1855 napoleon iii coin value begins with its metal content. This provides the intrinsic floor value that exists regardless of a coin's historical significance or condition.
Gold "Napoleons" were struck from 0.900 fine gold (90% gold, 10% copper). The copper alloy increased durability for circulation. The gold content is substantial:
- 10 Francs: 0.0933 troy ounces of pure gold.
- 20 Francs: 0.1867 troy ounces of pure gold.
- 100 Francs: 0.9330 troy ounces of pure gold.
To find the melt value, multiply the coin's gold content by the current spot price of gold. For example, if gold is at $2,000/oz, a 20 Francs coin contains about $373 worth of gold. However, these coins almost always sell for more due to their numismatic premium.
The 5 Francs silver coins are also 0.900 fine (90% silver). Each 25-gram coin contains 22.5 grams (about 0.72 troy ounces) of pure silver, giving it a solid baseline value that fluctuates with the price of silver.
In contrast, the bronze 5 and 10 Centimes coins have negligible metal value. Their worth is derived entirely from numismatic factors like condition, rarity, and collector demand.
Understanding your coin's metal content is crucial. It protects you from overpaying or underselling. You can track live precious metal prices with our Gold Price Today: Live Gold Price Chart & Historical Data to know what your coin's metal is worth at any moment. The beauty of these historical coins is that they will never be worthless; they will always retain their intrinsic precious metal value.

- 10 Francs (Gold): The most affordable gold Napoleon, averaging $260. Containing 0.0933 oz of gold, they are popular with collectors, with a record price of $1,500.
- 20 Francs (Gold): The sweet spot for investors and collectors. Averaging $510 with 0.1867 oz of gold, pristine examples can soar into the thousands, leading to the $15,275 record.
- 100 Francs (Gold): These large coins contain nearly an ounce of gold (0.9330 oz) and start around $3,600. They were statements of wealth and power.
How Rarity and Mintage Impact Value
Why did an 1855-A 20 Francs, one of over 16.5 million struck, sell for $15,275? The answer is survival rate. Most of those millions of coins were heavily circulated, damaged, or melted down. A coin that survived in pristine, uncirculated condition (graded MS64 or higher) is exceptionally rare, regardless of the original mintage.
Rare varieties and errors can also create immense value. While no major varieties are widely documented for 1855, errors like die variations or overdates can turn a common coin into a numismatic prize. The combination of exceptional preservation, a scarce mint mark, or a unique error is what lifts an 1855 napoleon iii coin value from valuable to extraordinary.
Historical Coins vs. Modern Bullion: Which Investment is for You?
When adding precious metals to your portfolio, you face a choice: historical coins like the 1855 Napoleon III or modern bullion. Both provide exposure to gold and silver, but they serve different investment goals.
Modern bullion is about acquiring pure metal at a low premium over the spot price. Historical coins are like owning a piece of art made from precious metal, where you pay for rarity and history in addition to the intrinsic value.
| Feature | Historical Gold Coins (e.g., 1855 Napoleon III 20 Francs) | Modern Gold Bullion (e.g., 1 oz Gold American Eagle) |
|---|---|---|
| Primary Value | Numismatic (collectible) + Melt Value | Melt Value (intrinsic metal content) |
| Premiums | Generally higher (due to rarity, history, condition) | Generally lower (closer to spot price) |
| Liquidity | Moderate to High (niche market for numismatic value) | Very High (easily bought/sold globally) |
| Fraud Protection | Face value and legal tender status offer added protection | Purity and weight guarantees, recognized by dealers |
| Collectibility | High (historical appeal, design, mint marks) | Low (standardized design, focus on metal) |
| Price Volatility | Influenced by metal spot price AND numismatic market | Primarily influenced by metal spot price |
The case for historical gold coins lies in their dual appeal. An 1855 Napoleon III coin is a tangible link to the Second French Empire. This historical legacy creates a numismatic premium that can grow independently of gold prices. Furthermore, their status as legal tender offers an added layer of fraud protection, as counterfeiting currency carries severe penalties. For more on historical coins, see our article on Discovering the Legacy of Liberty Head Gold Coins.
Modern bullion is ideal for maximizing your metal holdings. With lower premiums, more of your investment goes directly toward ounces of gold or silver. The high liquidity of coins like the American Eagle or bars means they are instantly recognized and easily traded worldwide. For a comparison of modern options, read our guide on Gold Bars vs. Coins.

Coins vs. Bars: Quick Comparison to Help You Decide
| Feature | Historical/Napoleon Gold Coins | Modern Gold Bars (e.g., 1 oz) |
|---|---|---|
| Legal Tender/Face Value | Yes (added fraud penalties for fakes) | No (bullion product) |

| Unit Size Flexibility | High (fractional weights like 20 Francs) | Often 1 oz and up |
| Liquidity for Small Sells | Strong (easy to sell piecemeal) | Best for larger, single transactions |
| Recognizability | High (Napoleon 20 Francs widely known) | High (well-known refiners) |
| Storage Efficiency | Good | Excellent (stackable, uniform) |
| Upside Beyond Metal | Yes (condition, rarity, mint mark) | Minimal (tracks spot price closely) |

Frequently Asked Questions about 1855 Napoleon III Coins
How do I know if my 1855 Napoleon III coin is real?
Authenticating your coin is a critical first step. Here are several checks you can perform:
- Check the Specs: A genuine 20 Francs gold coin weighs 6.45161 grams and is 21 mm in diameter. Counterfeits made from other metals often have incorrect weight or dimensions.
- Examine the Details: Authentic coins have sharp, precise details from being struck by dies. Fakes often appear soft, blurry, or show signs of casting, like small pits or a seam line on the edge.
- Verify the Edge: Many Napoleon III coins have a specific edge inscription (e.g., "DIEU PROTEGE LA FRANCE") or reeding pattern. Counterfeiters frequently get this detail wrong.
For high-value coins, professional authentication by a service like NGC or PCGS is the best way to be certain. They will verify its authenticity and grade, which also increases its resale value.
For more tips, our guide on How to Tell If Gold Is Real offers additional tests.
What is the most valuable 1855 Napoleon III coin?
Based on auction records, the most valuable is the 20 Francs gold coin with the "A" (Paris) mint mark in exceptional condition. One such coin sold for a record $15,275 in 2014. This price was achieved because the coin was in nearly perfect Mint State condition (likely graded MS64 or higher), making it extraordinarily rare despite a high original mintage.
While the 100 Francs coin has a higher melt value, the 20 Francs is more widely collected, driving up demand and prices for the finest-known examples. Condition is the key to achieving such record prices.
Should I clean my 1855 Napoleon III coin?
No. Absolutely not. Cleaning a historical coin is one of the most common and costly mistakes an owner can make. What appears to be dirt is often a natural patina that has developed over 170 years. Collectors value this patina as proof of the coin's age and authenticity.
Any form of cleaning, no matter how gentle, will create microscopic scratches on the coin's surface. This damage is irreversible and will cause the coin to be labeled as "cleaned" by grading services, which can reduce its numismatic value by 50% or more.
Your coin has survived for over a century and a half. The best thing you can do is preserve it as-is in a proper, non-PVC holder. Let its history shine through without interference.
