Frog Coin

Frog Coins, which are small, bright, lime-green coins, are a rare commodity in the Mushroom Kingdom. So rare infact, they are only found in Super Mario RPG: Legend of the Seven Stars. Tadpole Pond is the only place where they are accepted, and are used for buying rare and powerful items.

Unlike the Gold Coin, a Frog Coin makes a deep, musical clunking sound when picked up.

Rare Frog Coin
The Rare Frog Coin is an extremely valuable Frog Coin that was given to Mallow by his "grandfather"Frogfucius. Mallow was supposed to buy a Cricket Pie at the Mushroom Kingdom Item Shop with the coin; however, the coin was stolen by the thief Croco. As such, Mallow teamed up with Mario to find Croco and retrieve the coin. After defeating the crocodile thief in battle and recovering the Rare Frog Coin, Mallow headed back to the Mushroom Kingdom to purchase the pie. However, Mallow got even more sidetracked as he had to help liberate the Mushroom Kingdom from Mack and his Shyster army, who had recently conquered the peaceful kingdom. Eventually, after much work and effort, Mallow finally purchased the Cricket Pie with the Rare Frog Coin and headed back to Tadpole Pond, home of Frogfucius.
