The Wallet is item that appears in Super Mario RPG: Legend of the Seven Stars. It belongs to a Toad from Mushroom Kingdom. During the events of game, Croco steals it from him, as well as Mallow's Frog Coin. When Mario beat Croco, he left Wallet and the coin.
If we return Wallet to Toad, he will give us a Flower Tab. But Mario can as well sell it for one hundred and twenty-three coins at shop. However, the Toad will be very mad for a rest of game.
