Star Coins are collectibles found in the New Super Mario Bros. games as well as Mario and Donkey Kong: Minis on the Move and Mario Golf: World Tour. 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. If the player re-enters a level after finishing it, collected Star Coins will show up as translucent to show that it has been collected previously.
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 are replaced by Star Medals, which have a slightly different appearance but essentially the same function. Star Medals were then replaced by Green Stars in Super Mario 3D World, still serving the same purpose.
Star Coins appear again in New Super Mario Bros. 2. In this game, there are 219 Star Coins in total and they have similar uses to the Star Coins featured in New Super Mario Bros.. In World Star, Moon Coins appear instead.
