Doubloon

The doubloon (from Spanish doblón, or "double", i.e. double escudo) was a two-escudo gold coin worth approximately $4 (four Spanish dollars) or 32 reales,^[1] and weighing 6.766 grams (0.218 troy ounce) of 22-karat gold (or 0.917 fine; hence 6.2 g fine gold).^[2][3] Doubloons were minted in Spain and the viceroyalties of New Spain, Peru, and New Granada (modern-day Colombia, Ecuador, Panama, and Venezuela). As the Spanish escudo succeeded the heavier gold excelente (or ducado, ducat; 3.1 g vs 3.48 g fine gold) as the standard Spanish gold coin, the doubloon therefore succeeded the doble excelente or double-ducat denomination.

In modern times, the doubloon is remembered due in large part to the influence of historical fiction about piracy.^[4]
