About this subject

The Spanish gold doubloon, known as 'doubloon' in English, was the highest-value gold coin minted by the Spanish Empire between the 16th and 18th centuries. It was equivalent to 32 silver reals or 2 gold escudos, weighing approximately 6.77 grams of 22-karat gold (91.7% purity). Its name comes from the Spanish 'doblón,' meaning 'double,' because it was worth twice a gold escudo.

Initially produced in Seville and later in colonial mints such as Mexico City, Lima, and Potosí, the coin circulated widely across the Americas and Europe. The gold came mainly from mines in Peru and New Granada (modern Colombia). Doubloons were frequently used in transatlantic trade and to settle debts between empires.

The fame of doubloons grew with pirate literature and cinema. They are often depicted as gold coins in treasure chests buried on Caribbean islands. In reality, doubloons were rarely used in daily colonial life: their high value made them more suitable for large transactions or as a store of value. Many were eventually melted down to be turned into jewelry or ingots.

A technical curiosity: Spanish doubloons were hand-struck, featuring a crown and coat of arms on the obverse and the Jerusalem cross on the reverse. The edges were often irregularly clipped to prevent counterfeiting, a characteristic that today helps authenticators identify genuine pieces. Modern numismatics places high value on well-preserved specimens, especially the rare 8-escudo doubloons (or 'onza de oro'), which were equivalent to 16 Spanish dollars.
