dublon

A dublon was a Spanish gold coin. Its name comes from the Spanish word "doble," meaning double, as it was originally worth twice the value of a Spanish escu. The dublon was first minted in the 16th century, around 1535, under the reign of King Charles I of Spain. It was a significant denomination within the Spanish colonial monetary system.

The typical gold content of a dublon was high, contributing to its perceived value and its use in international trade. The design of the dublon often featured the portrait of the reigning Spanish monarch on one side and the Spanish coat of arms on the other. The coin's value fluctuated over time, but it was generally a substantial sum. The dublon was minted in various Spanish mints across the empire, including those in Seville, Mexico City, and Lima. Its widespread circulation meant it was a common sight in trade across the Americas and Europe. The dublon remained in production for several centuries until the monetary reforms in the late 19th century led to its discontinuation.
