Spanish gold coins, from whatever mint, were international trade coins widely used. The "pirate era" in the Carribbean, however, peaked between 1715 (when privateers for England and the Netherlands turned buccaneer because those countries were then granted free access to trade) and 1735 when the British and Dutch hanged the last of the notorious pirates. A "privateer" was a pirate employed by a government or private merchant. A "buccaneer" was a self-employed pirate.
