Smash Coins and Bills
Smash Coins and Bills (sometimes simply called Coins and Bills) are items that only appear in Coin Battle matches. Each coin has the Super Smash Bros. logo on it. Coins can be found in container items but are much more commonly produced by attacking opponents; the amount of money generated by a hit is roughly based on its damage and knockback. Coins will bounce a short distance when produced and can be picked up by touching them. Being hit by opponents does not cause one to lose coins (new coins are produced instead), but being KO'd will cause the player to lose half their coins (up to a maximum of 100 in Brawl). If the player is KO'd off the side (as opposed to the top or bottom), the lost coinage will be tossed onto the stage.
In Super Smash Bros. Melee, there were gold, silver, and copper/bronze smash coins, worth ten, five, and one point respectively. In Brawl, the coins were lowered in value to six, three, and one point respectively, but a new item, the Smash Bill, was introduced. Bills flutter and fly erratically, making them difficult to pick up, but they are worth 10 points each.
