Banana Coin

Banana Coins are the type of currency used in the Donkey Kong series games. They are golden coins with a banana or a banana bunch on them. These can be used to buy things like Cranky's advices and Wrinkly's save points.

Donkey Kong Country 2: Diddy's Kong Quest
This is the first game where the Banana Coins appear in. They are used for buying things from other Kongs, including Kong Kollege, Funky's Flights, and Swanky's Bonus Bonanza. They can also be used to get a rematch against a boss in the Game Boy Advance version.

Donkey Kong Land 2
Banana Coins return in Donkey Kong Land 2, with the same uses as in Donkey Kong Country 2: Diddy's Kong Quest, except that Swanky does not appear in this game.

Donkey Kong 64
In Donkey Kong 64, Banana Coins were used to buy certain items and upgrades such as Guns, new moves and abilities, and musical instruments. Special multicolored coins that were worth five regular coins can be found as well. Like the banana, coins come in the five Kong colors. There are currently known to be a total of 949 Banana Coins in Donkey Kong 64.
 * Donkey: 174, Diddy: 178, Lanky: 185, Tiny: 193, Chunky: 219
 * During the game, each Kong spends 21 coins on personal upgrades, Donkey spends an extra 2 on the DK Arcade game, and a total of 53 coins are spent on shared upgrades. At the end of the game, assuming Donkey pays for all shared upgrades, these are the totals you should have if you have collected them all:
 * Donkey: 98, Diddy: 157, Lanky: 164, Tiny: 172, Chunky: 198
 * Total: 789

DK: Jungle Climber
In DK: Jungle Climber, Banana Coins are found in each level and can be used to buy certain levels.

Donkey Kong Country Returns
In Donkey Kong Country Returns, Banana Coins are used to buy items, lives, and keys at Cranky's store. Banana Coins can be collected in some hard to reach places through levels and in the bonus rooms as well. A Banana Coin or multiple Banana Coins can be rewarded in the end game barrel upon the finish of a level. Banana Coins can also be rewarded by consecutive jumps on enemies.
