Purple Coins are coins that appear in galaxies with purple comets. The act differently than normal coins though. When Mario collects 100 purple coins, a star will appear. And if Mario dies, the purple coin counter will go back to 0.
- Purple coins do not heal Mario or add air to his air meter.
- Most levels contain only 100 purple coins, but in some levels there are 150 or even 110 purple coins in a level. The requirement to get 100 still stay the same.
