Musical Coins, also called coins, are special coins found in Wario Land 3. Musical Coins are bigger than regular ones and have a picture of a note on them. They are worth 10, similar to 10 Gold Coins. Only eight of them can be found in each level, however. If Wario collects all the Musical Coins found in the Music Box World, he unlocks the last golf course in the building found in the north part.
