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 (3.1 g fine gold) succeeded the heavier gold excelente (or ducado, ducat, 3.48 g) 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, in which gold coins were prime booty.
