History of the French 20 Francs Gold Rooster
The Coq d’Or — Marianne on one side, the Gallic rooster on the other — is continental Europe’s favorite small gold coin. Struck from 1899 to 1914 under the Latin Monetary Union standard, it matches the Swiss Vreneli and Italian and Belgian 20-franc pieces in weight and fineness, making all of them interchangeable bullion in European trade.
The French central bank restruck roosters in the 1950s using original dates, so individual dates are rarely scarce. The coin trades as compact, highly liquid bullion — a favorite of French and Benelux savers for over a century.
The 20 francs rooster was struck from 1899 to 1914 in 90% gold. Each coin weighs 6.45 grams (0.1867 oz gold). Production took place at Paris.
How much is a 20 francs rooster worth?
Like every collectible coin, the value of a 20 francs rooster comes down to grade, rarity and demand. The ranges below are approximate retail prices collectors pay for problem-free examples — coins that have been cleaned, scratched or holed usually trade well below these figures.
Printed price guides age quickly. The most honest benchmark is what comparable coins actually sold for, which is why CoinVault Pro shows live values built on Numista catalog data and real eBay sold results whenever it identifies a coin.
- Circulated (bullion): gold value + 2–6%
- Uncirculated: gold value + 5–12%
- Scarcer dates in true mint state: modest premiums
How to identify a genuine French 20 Francs Gold Rooster
Before you get excited about a potential find, confirm that the coin in your hand matches the genuine article. Work through this checklist:
When a coin fails any of these checks, treat it with suspicion. Modern counterfeits can be convincing at arm's length, but weight, dimensions and die details rarely lie.
- Standard: 6.45 grams of .900 gold, 21 mm — Latin Monetary Union specifications.
- Edge lettering changed in 1907 from "Dieu protège la France" to "Liberté Égalité Fraternité," splitting the series into two types.
- 1950s restrikes are indistinguishable from originals for practical purposes and trade identically.
