Doubloon

The doubloon (from Spanish doblón, meaning "double") was a two-escudo or 32-real gold coin; weighing 6.867 grams (0.218 troy ounces) in 1537, and 6.766 grams from 1728, of .92 fine gold (22-carat gold). Doubloons were minted in Spain, Mexico, Peru, and Nueva Granada. The term was first used to describe the golden excelente either because of its value of two ducats or because of the double portrait of Ferdinand and Isabella.
