Unlike most trading card games, due to the limited number of game pieces in each pack, some packs do not contain any Rare or Super Rare game pieces, or may contain multiple Rares. Any given set's Super-Rares will always come all together in the same pack. Each pack also contains a cardboard island (the reverse side in later sets has printed terrain such as a fog bank, sargasso sea, or reef), a checklist and set of rules, a crew/treasure card (which may include gold pieces for use in the game), and a mini-die. Each pack generally costs $4 US.
