Volunteer stamp

The Volunteer stamp is a Stamp on Club Penguin. It was first released on December 16th, 2010, along with the Top Volunteer stamp stamp for the Holiday Party 2010. To obtain this stamp, you must donate any amount of coins to any category.

How to Obtain
To obtain this stamp you must donate any number of coins to any cause in Coins for Change.

Glitch
One way to have obtained this stamp is to click one category and donate a random number of coins. For penguins that did not have enough coins, a message would appear saying you need more coins, but you would still get the stamp. This also worked for the Top Volunteer stamp.
