Coin is a mode of Vs. play in Super Smash Bros. Melee, Super Smash Bros. Brawl, and Super Smash Bros. for Wii U. The objective is to collect as many Smash Coins - and, in Brawl and Wii U, Smash Bills - as possible. Coin Battles are timed, and the player holding the most Smash Coins at the end of the match wins.
In Super Smash Bros for Wii U, Coin Battles cannot be played in 8-Player Smash.
Coin battles have been removed entirely in Super Smash Bros. Ultimate.
Coins are produced when any attack hits an opponent. The amount and value of the coins released depends on the strength of the attack. Smash coins thrown from a player will not be deducted from their tally, but being KO'd will cause the player to lose half their coins (to a maximum of 100 in Brawl and for Wii U). Several gold coins will also be launched from the blast zone, and may be grabbed if close enough to the stage.
In Melee, there are copper, silver, and gold Smash Coins, worth one, five, and ten points respectively. In Brawl, the coins were lowered in value to one, three, and six points respectively, while a new item, the Smash Bill, is introduced. Bills flutter and fly erratically, making them difficult to pick up, but they are worth 10 points each. In for Wii U, the Smash Bill is worth 6 points.
