Golden Coin

The 6 Golden Coins, or simply the Golden Coins or 6 Coins, are six titular artifacts of Super Mario Land 2: 6 Golden Coins. All of them are needed to open the gate to Mario's castle in Mario Land. Each coin represents a different zone of the land: the Tree Zone, the Space Zone, the Macro Zone, the Pumpkin Zone, the Mario Zone, and the Turtle Zone. After Mario returns from his battles with Tatanga in Sarasaland, the hero discovers his castle occupied by the jealous Wario. During Wario's conquest of Mario Land, the yellow-clad villain captures Mario's castle, scatters the palace's coins across the land, and places the inhabitants under a spell. Ultimately, Mario recovers the 6 Golden Coins from Wario's minions and opens the gate to the castle to engage the villain in a one-on-one battle for Mario Land. If the player gets a Game Over, any Golden Coins collected by Mario are returned to Wario's six guards, and Mario has to collect them all over.
