1) What defines the value of an antique coin?

The value of an ancient coin is not based solely on its date or precious metal weight. Experts and collectors take a number of other factors into account, such as :

• The history of the coin. Indeed, some coins were minted at emblematic periods or represent famous figures (Napoleon, for example).
• State of preservation. This is a very important factor, as a well-preserved and well-maintained coin can increase in value.
• Rarity. It's generally accepted that "what's rare is expensive". This adage holds true in the collectibles market.
• Market demand. The price of an antique coin fluctuates according to the interest of collectors and investors.

As you can see, a coin can be worth much more than just its gold or silver content. That's why it's essential to consult our certified experts for the best possible advice.

2) Why collect old coins?

In addition to offering diversification, coin collecting can be a real investment lever. Antique coins represent a tangible store of value, less exposed to the vagaries of the economy than other financial investments.

What's more, they are prized by enthusiasts the world over, ensuring liquidity on the market.

3) Highly sought-after vintage pieces

Among gold coins, there are many old French coins that are particularly sought-after. And when it comes to silver coins, there are many more to collect.

Here are some of the most emblematic gold and silver coins:

- LES 20 FRANCS NAPOLEON Ier (1815)

A true piece of history symbolizing the First Empire, the 20 Francs Napoléon Ier 1815 Paris coin is highly sought-after. Indeed, these gold coins embody imperial prestige, and their historical rarity makes them highly collectible.

- 20 GOLD FRANCS MARIANNE COQ (1898-1914)

Widely inherited by French families, the 20 Franc Coq Marianne coin is emblematic of the Third Republic. Certain years of issue or perfect states of preservation increase its value.

- GOLD LOUIS

Emblematic royal coins of the Ancien Régime (XVIIᵉ and XVIIIᵉ centuries), gold Louis are a symbol of prestige and royal power. These coins still circulate on the numismatic market and fetch high prices, especially for rare vintages or exceptional mintages.

- 100 FRANCS BAZOR (1935)

The 100 Franc Bazor coin dates from the Third Republic period. Most examples were recast before the Second World War, making this a rare coin for collectors to find.

- 20 FRANCS TURIN (1936)

This silver 20 Francs Turin 1936 coin embodies the Art Deco style and appeals to collectors for its aesthetics and low circulation. This is the first Marianne in our numismatic history to be crowned with laurels.

To be complete on the subject, don't miss the many French coins from the XIXᵉ and XXᵉ centuries that can be of particular interest:

• Coins minted during the Third Republic
• Semi-numismatic issues such as certain semi-numismatic gold coins
• More common French silver coins, but whose quality may surprise experts.

4) How to recognize and value your old coins?

To determine the value of your coins, we recommend you check the following:

• The year and provenance of the coin. Some years of issue are particularly rare.
• The condition of the coin. The slightest scratch or wear can greatly reduce the value.
• The numismatic value. To find out, read this article on the value of a numismatic coin.
• Consult one of our experts. Indeed, a professional will know how best to value a coin according to the current market.

5) What to do if you think you own a rare coin?

If you come across a piece you think is valuable, it's important to take the following precautions before having it appraised:

• Do not clean the piece yourself, as this can irreparably damage its surface and ultimately its market value.
• Keep it in protective packaging to avoid humidity and oxidation.
• Have the part appraised by a specialist

Conclusion

Many people unknowingly own ancient coins that are worth far more than their weight in metal. But you still need to have the curiosity to find out what it is, and then call in a professional to avoid undervaluation. The next time you open an old box or rummage through the family attic, remember that behind a simple antique coin may lie a real treasure.
