Coin

The Coin is the only currency of Club Penguin. Fluffy the Fish is engraved on each coin. Coins are earned by playing games and taking part in special activities, such as Igloo and Clothing competitions. Players can use coins to buy colors, Puffles, Puffle supplies, Clothing, Igloo Upgrades, furniture, and player card backgrounds. Coins can also be used to send post cards. However, non members are only allowed limited use of their coins:
 * Buying Colours for the Avatar
 * Buying Player Card Backgrounds
 * Red & Blue Puffles
 * Post Cards
 * Food & Bathing supplies for Puffles
 * Donation for the certain events, such as Coins for Change

"Ten" coins
A "ten" coin is shaped like a normal Club Penguin coin but is worth 10 coins. It is also larger than normal coins. It is only found in the game Jet Pack Adventure.

Coins for Change
In December 2007 and 2008, there was a Coins for Change program. Here is what it was about:

''More than 2.5 million children donated in excess of 2 billion virtual coins they earned playing games on Club Penguin to support the environment, children’s health or children in developing countries. Through their virtual donations, the kids directed how much of a $1 million cash donation went to three charitable organizations chosen to represent those areas.''
