The Expert's Take

Meaning and Context
The Louis d'or was a prestigious gold coin first minted in 1640 under the reign of King Louis XIII, marking a pivotal reform in French monetary history. Conceived by his chief minister, Cardinal Richelieu, and executed by the financial superintendent Claude de Bullion, the coin was introduced to stabilize the French economy and provide a reliable, high-value currency for international trade and state finance. It served as the principal gold coin of the Ancien Régime, with its weight and fineness meticulously regulated, and featured a portrait of the reigning monarch—successively Louis XIII, Louis XIV, Louis XV, and Louis XVI—on its obverse, symbolizing royal authority. The coin's production ceased following the French Revolution in 1793, superseded by the franc, making original Louis d'or coins highly sought-after by numismatists and collectors of antique gold coins. Its legacy endures as a powerful emblem of Bourbon France's economic power and artistic craftsmanship in precious metal coinage.
Common Mistakes and Alternative Spellings
The standard and correct spelling is Louis d'or, which includes an apostrophe and a space. A common alternative spelling is Louis-d'or, using a hyphen instead of a space, which is also historically accepted and frequently encountered in catalogs and older texts. Frequent misspellings and typos arise from omitting the apostrophe, resulting in forms like Louis dor or Louis d or. Others incorrectly capitalize the 'd' as in Louis D'or, or merge the entire term as Louisdor. The plural is typically Louis d'or, remaining unchanged, though Louis d'ors is sometimes seen informally. Non-French speakers may also mistakenly write Louis d'or coin, which is redundant as "d'or" already implies "of gold," but this phrasing is commonly used in English to clarify the term for a general audience.
