10 Francs Gold

The 10 Franc gold coin, weighing exactly 3.225 grams of 900 fine gold, circulated as a workhorse of everyday transactions in 19th-century France.

That precision in weight and purity stemmed from France's role in the Latin Monetary Union, which aimed to standardize coinage across Europe from 1865 onward. Designs varied by era: early issues bore the Republic's bare head, while later ones featured Napoleon III's portrait after 1852. Some years saw mintages in the millions, though records for specific dates were scattered during the upheavals of the Franco-Prussian War.

Struck at the Paris Mint and occasionally Bordeaux or Lyon, these coins often included a small privy mark, like a cornucopia, to denote their source. Variations exist, but most survive in decent condition, free from the romantic myths that collectors love to spin.

It's a coin that did its job quietly, without the drama.
