Moon Coin

Moon Coins are types of Star Coins that only appear in World Star of New Super Mario Bros. 2. They have moons that resemble a 3-Up Moon imprinted on them rather than stars. These coins, however, cannot be used as Star Coins (therefore they cannot be used to remove Star Coin Signs) and are only for collecting and are required to obtain a star icon on the player's profile and unlocking unlimited Toad Houses.
