French Constitutional Ecu

The French Constitutional Ecu is a large silver coin struck during the short-lived constitutional monarchy of the French Revolution. The example shown is dated 1792 and carries a left-facing bust of Louis XVI on the obverse, paired with a standing allegorical figure of Liberty holding fasces on the reverse.

Often called the ecu de 6 livres, it is a crown-sized piece and one of the most recognizable coins of the Revolutionary era. The design captures a unique political moment: a king still shown on the coinage, but styled as monarch under the new Constitution rather than by divine right.

After the Revolution of 1789, France adopted a constitution in 1791 that made Louis XVI a limited, constitutional monarch. New coinage reflected the change: the old royal titles gave way to legends styling Louis as King of the French rather than King of France, and Revolutionary emblems such as the fasces (a bundle of rods symbolizing unity and civic authority) appeared alongside the royal portrait.

These large silver ecus were struck mainly in 1792, dated in the Revolutionary style as years of Liberty. They circulated only briefly. The monarchy was abolished in September 1792 and Louis XVI was executed in January 1793, after which the Republic issued coinage without any royal image.

Because it belongs to this narrow transitional window, the Constitutional Ecu is a tangible relic of the moment when France was neither an absolute monarchy nor yet a republic.

Obverse: a left-facing bust of Louis XVI, surrounded by a French legend naming him as king of the French. Below or around the portrait you will typically find the engraver's detail and the date 1792.

Reverse: a standing allegorical figure associated with Liberty and the Genius of France, shown beside fasces with the emblems of the new order. Revolutionary legends referring to the law and the nation frame the design, along with the value and date.

Physical clues: this is a crown-sized silver coin, roughly 39-41 mm across and about 29 grams, struck in high-grade silver with a lettered or decorated edge. Small letters or symbols in the design mark the mint and officials responsible for the striking.

Value depends heavily on grade, mint, and eye appeal. As a large silver coin from a famous and brief historical period, even well-worn examples carry a clear premium over their silver content, while sharp, high-grade pieces are considerably more desirable.

Some mints and die varieties are much scarcer than others, so two coins of the same 1792 date can differ widely in worth. For a realistic figure, compare recent auction results for the same mint mark and condition, and be cautious of cleaned or damaged pieces, which sell at a discount.
