Doubloon

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.

After the War of 1812, doubloons of eight were valued in Nova Scotia at the rate of £4 and became the dominant coin there.

Since the prevailing ratio in Europe was 15 in most of the 18th century, doubloons occasionally traded at a discount to this amount, at 30–32 reales.

In Spain, doubloons were current for $4 (four duros, or 80 reales de vellón) up to the middle of the 19th century.

After their independence, the former Spanish Viceroyalties of Mexico, Peru and New Granada continued to mint doubloons.
