The doubloon was a two-escudo gold coin worth approximately $4 or 32 reales, and weighing 6.766 grams of 22-karat gold . Doubloons were minted in Spain and the viceroyalties of New Spain, Peru, and New Granada. As the Spanish escudo succeeded the heavier gold excelente as the standard Spanish gold coin, the doubloon therefore succeeded the doble excelente or double-ducat denomination.

The Brasher Doubloon is a rare American doubloon of eight escudos worth sixteen dollars, privately minted in and after 1787.
