There are two kinds of currency in Pirate101, and they can be obtained and used in different ways.
Pirates earn gold by completing quests, checking loot after defeating others in combat, and keeping an eye out for treasure chests! Gold can also be bought from the Crown Shop for Crowns. You can use gold to buy tons of things in Pirate101 including gear, ships, ship equipment, pets, resetting Companion talents (Members only) and more. Gold does not transfer between Pirate101 and Wizard101.
Crowns are a special currency that can be bought from Pirate101.com for real life money. Players can use Crowns for special items in the Crown shop and game actions such as resetting a Companion's talents. Crowns do transfer between Pirate101 and Wizard101 and can be used in both games.
