Rarity

Rarity is a measure for items that are exclusive to a group of players. An item is defined as rare if it is old and has not been reintroduced.

Definition
A player who has had an account for a very long time usually owns many rare items, and is generally looked up on by newer players. For example, the Hawaiian Lei given out in January 2006 - 3 months after the public release of Club Penguin - is considered rare because many players who had it have stopped playing the game, leaving a small amount of players still with item and rendering it rare to come by. Players usually demonstrate their "rareness" by wearing their oldest clothes and showing their ability to match the clothes of any penguin they come across, leading to competitions where players try and match each other until one fails to do so.

Rare items
Rare items are either old, making them not always available, which makes it "rare" or one-time items (Anniversary hats, pins, etc). Rarity is a long sought after goal in new penguins.

The items listed below are "rare" because they're only available in some parties, etc. Some of them will never return (confirmed by the Club Penguin Team).

Trivia

 * Many new penguins want to be rare, and plead to Club Penguin for the rare items to come back, although ironically they won't be rare anymore. Despite this obviousness, Club Penguin have reintroduced nearly all rare items that were available to non members.
 * Anniversary hats and Pins will never come back, making the Beta Hat and Shamrock Pin the rarest items you can get.
 * Many rare penguins tease non-rare penguins and show-off their items. New penguins are tired and annoyed of this.
 * Club Penguin Moderators and Staff are catching on to this new craze and have brought back items like the Black Toque or the Black Superhero mask.
 * Most rare items are normally non-member, such as party hats, Red and White shirt, Eye Patch, etc.
 * Club Penguin confirms that all rare items (except pins and party hats) will come back some time, which may make a lot of rare penguins disappointed while making new penguins excited.
