From revolutionary Genius to republican napoléon
In 1792, the chief engraver Augustin Dupré drew this Genius busy engraving a tablet for the young First Republic. The design waited until 1848 to reach a gold 20 francs: the Second Republic had it struck in 1848 and again in 1849, before the Empire put the emperor's profile on the Napoleon III 20 francs.
In 1871, the Third Republic took up the Genius at once. The 1870s were prolific; then nothing from 1880 to 1885, and modest volumes until 1894, the period every rare date comes from. Output picked up strongly in 1895. The Genius followed the Latin Monetary Union's rules and was used for everyday payments in France until 1914.
In 1899, Jules-Clément Chaplain's 20 francs Rooster took over, at the same weight. The Genius did not vanish, though: it still adorned the gold 50 francs until 1904 and the gold 100 francs until 1914. The nickname “angel”, often used in French, comes from the figure's wings, yet the figure is a republican allegory. For the wider period: Third Republic coinage (in French).
Varieties worth knowing
For any one date, the only recognised differences concern the privy marks, tiny reverse symbols, one for the Mint director and one for the chief engraver. 1879 exists with a plain anchor or a barred anchor. 1896 exists with a fasces or with a torch; the Le Franc catalogue gives each a separate number.
Burnished flans form a category of their own: presentation pieces, struck in 1848, in 1878 (30 coins, plain edge) and in 1889 (100 coins). They were not meant to circulate and stand apart from the regular coins of the same year.
A doubtful coin: the checkpoints
Start with the mint letter: since Paris was the only mint for the Genius, any mark other than A is enough to make the coin suspect. Then check weight and size, 6.45 g for 21 mm, and the edge, which should be crisp and even.
Period or modern counterfeits, sometimes cast in gold of the right fineness, often show soft details: barely marked wing feathers, a blurred rooster, irregular edge letters. Rare dates raise another problem. An 1888 or an 1892 may be a genuine coin of a common year whose last digit has been changed: examine its shape and alignment under a loupe, along with scratches or unusual polish in the field around it. The gold is real, the rarity is not. Each step is set out in our French page on fake coins.
Wear: where to look
On the obverse, wear first attacks whatever stands highest: the Genius's head, shoulder and chest. The wing feathers fade next, then the rooster's detail and the rods of the fasces. As long as the feathers stay separate and the profile is sharp, it grades Very Fine (TTB in French terms); once the wings turn smooth and the rooster loses its detail, it is Fine (TB).
On the reverse, the wreath is the right indicator: do its leaves keep their veins? The legends, close to the rim, fade too late to serve as a guide. Small knock marks in the fields, even on a lightly circulated coin, also lower the grade. Never rub the coin to make it shine: its original lustre would be lost.
