Obverse
The 20 Francs Napoléon in gold encompasses several distinct types issued under different political regimes. Each series features an obverse specific to its era:
Napoléon Bonaparte Premier Consul (An XI – An XII / 1803-1804): Depicts the bust in civilian dress turned to the right, encircled by the legend "BONAPARTE PREMIER CONSUL" (engraved by Augustin Dupré and then Jean-Pierre Droz).
Napoléon Ier Emperor (1804–1815): Divided into several sub-types (bare or laureate head, with or without the title EMPEREUR, reverse République française or Empire français). Principal engravers: Jean-Pierre Droz and Nicolas-Pierre Tiolier.
Napoléon III (1852–1870): Struck under the Second Empire with the legend "NAPOLEON III EMPEREUR". A distinction is made between the bare head (1852-1860) and the laureate head (1861-1870), engraved by Albert Désiré Barre.
Génie de la République (1871–1898): Displays the winged figure of the Genius writing the Constitution, engraved by Augustin Dupré after the 1792 model.
Marianne Coq (1899–1914): The last major issue of the monetary saga, engraved by Jules-Clément Chaplain, bearing the profile of the Republic on the obverse and the Rooster on the reverse.
Reverse
The reverse of the Napoléon retains essential constants: the face value 20 FRANCS, the mintage year (year of striking) and the mint mark letter indicating the place of manufacture.
Evolution of the reverse design
First Consul & Napoléon Ier : Laurel wreath surrounding the face value, with the legend « REPUBLIQUE FRANÇAISE » then « EMPIRE FRANÇAIS ».
Napoléon III : Heraldic imperial eagle surrounded by the legend « EMPIRE FRANÇAIS ».
Génie & Marianne Coq : Return to the vegetal wreath with the inscription « REPUBLIQUE FRANÇAISE », accompanied by the engraver's signature and the privy marks (symbols of the Mint director and the chief engraver).
The main minting workshops
The mint mark letter identifies the city where the coin was struck:
Letter / Symbol Mint city Observation A Paris Main workshop (highest mintages). BB Strasbourg Very active workshop in the 19th century. D Lyon Frequent provincial workshop. K Bordeaux Common provincial workshop. MA Marseille Mediterranean strikings. U / G Turin / Geneva Workshops under Napoleonic dominion (rare strikings).
Impact on value: Certain mintage years combined with low-mintage provincial workshops (such as Consular strikings or short-lived workshops) are significantly rarer. These rare coins command a high numismatic premium, well above their simple metal value.
History of the 20 Francs Napoléon Coin
The 20 Francs Gold coin is France's most iconic investment coin. Its history spans nearly two centuries, giving it an unrivalled heritage legitimacy.
1803 (Year XI): Born under the Consulate with the creation of the Franc Germinal by Napoléon Bonaparte.
Historical continuity: Struck under the First Empire, the Restoration, the July Monarchy, the Second Empire, the Third Republic and the Latin Union until 1914.
Global standardisation: Gross weight of 6.45 g at a fineness of 900 ‰ (i.e. 5.81 g of pure gold), adopted by dozens of countries for its liquidity.
Terminology: The name "Napoléon" generically refers to all French 20 Francs Gold coins, regardless of the effigy depicted.
Safe-haven asset: Withdrawn from circulation during the First World War, it became the symbol of family wealth passed down from generation to generation.
Evolution of the Napoléon Price (2005 – 2026)
Over two decades, the 20 Francs Napoléon has illustrated its role as a shield against inflation and a long-term store of value:
2005: A gold price of around 14,000 €/kg placed the Napoléon between €85 and €95.
2008 – 2012 (Financial crises): The subprime crisis and sovereign debt crises pushed the coin beyond €200.
2020 (Pandemic & Quantitative Easing): Driven by central bank monetary policies, the price exceeded €300.
2024 – 2026 (Geopolitical tensions & De-dollarisation): Gold broke historic highs (over 90,000 €/kg in 2025), pushing the Napoléon above €520 to €540.
Key takeaway: Over 20 years, the Napoléon has multiplied its value by 5 or 6, outperforming almost all traditional bank investments (Livret A, government bonds).
How Is a Coin's Value Determined?
The price of a Napoléon is based on the sum of two components: Metal Value + Market Premium.
1. The Intrinsic Value (Metal)
This corresponds to the weight of pure gold contained in the coin:
5.8064 g (Pure Gold) × Spot Price (€/g)
2. The Market Premium
Expressed as a percentage (often between 2% and 8%), it varies according to market demand, condition and the rarity of the year of issue.
Calculation example:
• Gold spot price: 90,000 € / kg (90 € / g)
• Metal value: 5.8064 g × 90 € = 522.57 €
• Market premium (4%): + 20.90 €
= Estimated purchase price: 543.47 €
The Buy / Sell Spread: The Napoléon offers one of the lowest spreads on the French market (a narrow gap between the buying price and the resale price), ensuring excellent financial efficiency.

Frequently asked questions
What are the different effigies of the 20 Francs Or?
Several portraits have succeeded one another on the 20 Francs Or coin throughout the various French political regimes:
Napoléon Bonaparte (Consul, Year XI to Year XIII): Profile of the First Consul, highly sought-after coins commanding a significant numismatic premium.
Napoléon Ier (Emperor, 1806-1815): Bare-headed or laureate profile.
Louis XVIII and Charles X: Coins from the Restoration period, rarer on the market.
Louis-Philippe Ier: Effigy of the "citizen-king" with his characteristic hairstyle.
Napoléon III (1852-1870): Two types (bare head and laureate head), among the most abundant and widely traded.
Génie de la République & Marianne (Cérès): Republican effigies from the IIᵉ and IIIᵉ Republics.
Coq Marianne (1899-1914): The most popular and most liquid version on the modern market.
All these effigies share a strictly identical metal value. The most common types (Napoléon III, Coq Marianne) are to be preferred for a purely financial investment thanks to their maximum liquidity. Consular or rare strikes are better suited to collectors due to their numismatic premium.
Why is the 20 Francs Napoléon considered the benchmark for investment gold in France?
It is the most popular and most traded gold coin on the French market. With tens of millions of specimens minted, it benefits from perfect liquidity: it can be bought and resold very easily at any dealer or gold counter.
Furthermore, it offers a moderate premium that tends to rise sharply during periods of economic crisis.
What is the engraved edge on a 20 Francs Napoléon?
The edge inscription depends on the period of issue:
Under Napoleon I and the monarchs of the Restoration, the edge bears the raised inscription "Dieu protège la France".
Under the Second Republic and Napoleon III, "Dieu protège la France" is also found.
From the Third Republic onwards (on the Cérès and Marianne Coq types), the inscription becomes "Liberté Égalité Fraternité".
How to preserve the value and premium of your 20 Francs Napoléon?
To preserve its premium, the coin must not undergo any alteration. It should never be cleaned or rubbed (which would create micro-scratches and cause it to lose its original condition).
It is strongly recommended to store it in a sealed bag with its inventory number, which guarantees its authenticity and facilitates the application of the capital gains tax regime upon resale.
What is the difference between a Louis d'or and a 20 Francs Napoléon?
In common usage, the term "Louis d'or" is very often mistakenly used to refer to a 20 Francs Napoléon.
Historically, a genuine Louis d'or is a royal coin struck under the Ancien Régime (from Louis XIII to Louis XVI, between 1640 and 1792).
The Napoléon was created by Bonaparte in 1803 under the Franc Germinal system. Although they share a strong symbolic significance, the 20 Francs Napoléon is a republican or imperial coin weighing 6.45 g, whereas the true Louis d'or is an older and rarer numismatic collectible coin.
