Coin

Coins are collectibles in Super Mario 64. They are yellow circles with stars on them. When collected, the coin counter is increased. You can obtain a star by collecting 100 coins in a level. Collecting coins can also heal the player. There are 3 types of coins:


 * Yellow Coin: The standard type of coin, giving 1 health and increases the coin counter by 1.
 * Red Coin: The second most common type of coin, giving 2 health an increasing the coin counter by 2. Collecting 8 red coins in a level can reward the player with a star.
 * Blue Coin: The rarest type of coin, and larger than the rest. Blue coins give 5 health and increase the coin counter by 5. Blue coins are only dropped by some enemies, or found by pressing a blue coin switch, which will spawn blue coins for a limited amount of time.

Coin Discoloring
Main Article: Coin Discoloring

Coin Discoloring is a phenomena similar to Enemy Discoloring where the Personalization A.I. creates new types of coins with unique properties. These are usually beneficial to the player, and can appear if the player is doing poorly.

Luring Coin
The Luring Coin is the name given to an unused behavior for a red coin. It will stay a set distance away from the player, making the player attempt to approach it to collect it despite the fact it cannot be obtained. This has been reportedly reworked into a Coin Discoloring with a cyan coin, though some have reported this behavior being a standalone anomaly, usually found in Shifting Sand Land, potentially representing a mirage.
