Expedición a México Medal. Napoleón III (1863)

Silver decoration medal of the Expedition to Mexico issued in the time of Napoleon III, dated 1863 and engraved by Barre, engraver of the Paris mint.

This piece belongs to the invading side: it was a French decoration for the troops that took part in the French Intervention in Mexico, ordered by Emperor Napoleon III. In 1863, after the setback of May 5, the French took Puebla and then Mexico City, clearing the way for Maximilian's Second Empire.

Its presence in a Mexican catalog has historical value: it recalls, from the invader's perspective, that European attempt to impose a monarchy on Mexico. Barre's fine workmanship reflects the French medallic tradition applied to a military campaign that would end in failure.

The "Expedición a México. Napoleón III" medal was struck in 1863. It is made of silver, measures 30.65 mm in diameter and weighs 14.77 grams, minted in Mexico, the work of the engraver Barre. In the specialized catalog it is referenced as Grove, Medals of México, III #D-290a.

Being a silver medal, its value has a floor: the precious metal content (14.77 grams). Above that, what drives it up is the condition, the small size of the issue, and the interest in the theme it commemorates (Expedición a México. Napoleón III). A piece with no wear and its original case is worth considerably more than a handled one.
