Purple Coin

Purple Coins are special Coins that appeared in Super Mario Galaxy. They will only appear in the regular galaxies when a Purple Comet is in orbit of a Galaxy.

The player will always need to collect one-hundred Purple Coins to make a Power Star appear. Purple Coin Missions sometimes have a time limit. When there is a time limit, the Purple Coins are usually either set along a linear path, or over will appear and only one hundred of them will need to be collected. Additionally, once the Power Star appears, the player must collect it before the remaining time runs out.

In missions that aren't timed, the Purple Coins will be spread out across the level, requiring the player to explore every area in order to find them all.

There are two Purple Coin missions that are not activated by a Purple Comet. One is in the Gateway Galaxy and another in the Grand Finale Galaxy.

All of the timed Purple Coin Galaxies, along with Battlerock Galaxy and Dreadnought Galaxy have a theme that is a remix of Gusty Garden Galaxy's theme.

Also, unlike the standard Yellow Coins, Purple Coins will not restore any of the player's health, nor refill the air gauge while underwater.

Purple Coins re-appear in Super Mario Galaxy 2, though not in every galaxy as it was in the prequel. In the Rolling Coaster Galaxy, a Purple Coin will be in a ball, replacing the Star Ball. This is called a Purple Coin Ball. Also to note in this game, Player 2 can collect Purple Coins for Player 1 along with Yellow Coins.

Purple Coins also appear in the Super Mario Galaxy Trading Cards.
