Five Coin

Five Coins are a larger type of coin worth five normal coins apiece, mostly found in the Mario & Luigi series.

Mario & Luigi series
Five Coins are concealed within blocks in most of the Mario & Luigi series. In Mario & Luigi: Paper Jam, Five Coins can occasionally be found scattered around outside blocks.

Super Princess Peach
In Super Princess Peach, large coins that are worth five regular ones appear in levels alongside other types of coins, but they are notably less common. Upon buying a Courage Soda, every enemy Princess Peach whacks with Perry gives out such a coin, with the number of coins dropped increasing by 2.5 for every two enemies when whacked in rapid succession.

Paper Mario: Sticker Star
Five Coins are also encountered in Paper Mario: Sticker Star, where they are sometimes dropped by enemies upon defeat or at a level's completion.

Monopoly: Super Mario Celebration!
Five Coins appear in Monopoly: Super Mario Celebration! as a currency. They can be used to pay for items or fees, counting as five normal coins.

Jenga: Super Mario Edition
In Jenga: Super Mario Edition, Five Coins can be used in place of regular coins to physically denote the number of coins that a player has earned.
