Star Coin

"You need 5 Star Coins to pass this area. Do you want to spend the Star Coins?"

- Star Coin Sign

Star Coins are collectibles found in New Super Mario Bros. games. Three Star Coins appear in each level where some are easy to collect, while others require special power-ups such as the Mini Mushroom or the Blue Shell to access.

In New Super Mario Bros. there are eighty levels, thus there are 240 Star Coins to find in the game. Each Star Coin adds 1,000 points to the player's game score.

They also appear in New Super Mario Bros. Wii. In this game, there are 231 Star Coins. Three Star Coins appear in each of the game's seventy-seven levels much like New Super Mario Bros. Also, collecting one adds 4,000 points to the player's total score, instead of 1,000 like in its predecessor.

In Super Mario 3D Land, they also appeared, though with a slight name change to "Star Medal". Although they did not appear in Super Mario Galaxy 2 directly, very similar items called Comet Medals appear.

They have appeared in New Super Mario Bros. 2, where the name was changed back to "Star Coin". In this game, there are 219 Star Coins in total and they act relatively similar to the Star Coins featured in the original New Super Mario Bros.

Star Coins made their return once again in New Super Mario Bros. U, where they hold the same purpose as New Super Mario Bros. 2 and the original New Super Mario Bros.

Super Mario World
In Super Mario World, a similar concept exists : Dragon Coins. Unlike the Star Coins, the player must get the five dragon coins in a level on one try.

New Super Mario Bros.

 * Uses:
 * One use is for opening Star Coin Signs leading to Toad Houses or bonus letter levels (e.g. 1-A or 5-B). There are 32 of these signs in the game, each requiring 5 Star Coins to open. After Mario opens the signs, he is has an option to save, allowing him to easily save his progress without completing an uncompleted tower or castle before completing the game.
 * Another use is for buying new backgrounds. After completing the game at least once, a blue Toad House will appear north of level 1-1. There are 5 bonus backgrounds for the Touch Screen that cost 20 Star Coins each. The 5th background can be unlocked by opening every Toad House.
 * Once all 240 Star Coins have been collected, a 2nd star will appear next to the save file. There will also be a message on the Touch Screen next to the Star Coin symbol reading "Complete".
 * Spending all the Star Coins not only unlocks the final Touch Screen background, but also leaves a message next to the Star Coin symbol on the top screen in the world map reading "All Spent".

New Super Mario Bros. Wii

 * Uses:
 * One use is for buying Hint Movies at Princess Peach's Castle.
 * Another use is collecting all Star Coins in a world so a level in World 9 (unlocked after beating final boss) is unlocked. It will be the level number corresponding to the world number (e.g. collecting the Star Coins in World 1 will unlock 9-1).
 * The final use for a Star Coin is to cause a star to be displayed on the File Select Screen. If the player collects all twenty-four Star Coins in World 9, he or she will earn a star. Collecting all Star Coins in the game will also result in getting a second star.

Super Mario 3D Land
In Super Mario 3D Land, Star Medals are the equivalent of Star Coins. There are three in every level, like in the New Super Mario Bros. games. They are used to unlock other courses, serving the purpose of Power Stars from past 3D platformers. The Star Medals have a similar appearance to Comet Medals from Super Mario Galaxy 2, but they have stars on them instead of comets. There are 285 Star Medals in the game's levels (including the Special Worlds), plus 51 in the Mystery Boxes, leading to a total of 336 to be collected. It is confirmed that through StreetPass Mystery Boxes the player can obtain 999 Star Medals although this serves no purpose as only 290 are needed to unlock all levels. When the player collects a Star Medal they have already collected in a level, they instead earn three Coins. Also, when the player opens a course with Star Medals, the players pay their medals, but they are refunded back to the player afterwards.

New Super Mario Bros. 2
Star Coins reappear in New Super Mario Bros. 2. In this game, they are back to their original design. A similar type of coin known as a Moon Coin appears in World Star. These coins have moons from Super Mario World printed on them instead of stars, and do not count towards the Star Coin total.
 * Uses:
 * Like in the first New Super Mario Bros., the Star Coins are used to open Star Coin Signs, leading to Toad Houses or secret levels.
 * 90 Star Coins are required to unlock the levels in World Star.

New Super Mario Bros. U
Star Coins once again appear in New Super Mario Bros. U. Their purpose is the same as in New Super Mario Bros. Wii, where collecting all the Star Coins in each world unlocks a level in Superstar Road. There are in total 246 Star Coins in the game.
