Wario (Series)

As you would expect, the Wario series does indeed feature coins.

Wario Land
Out of the two main Wario franchises, Wario Land has much more coins than WarioWare.

1 Gold Coin
The name "1 Gold Coin" is only used in Super Mario Land 3 : Wario Land, however in this section it will be used for standard coins throughout the whole series that are only worth one coin.

Super Mario Land 3 : Wario Land
1 Gold Coins in this game are almost identical to the coins from the Mario series, which makes sense considering the game has "Mario" in the title. In the game, coins can be spent on the two minigames that are playable after each level. One of them gives you a chance to either double or halve your coin count, and the other gives you a chance to earn extra lives. Coins are also important in determining the ending that the player will get, as the more coins and treasures that you have collected throughout the game will determine how good the castle Wario gets is.

Wario Land II
In Wario Land II, coins can be obtained lying around, by destroying blocks, or by defeating enemies. Since Wario has no health system in this game, he will lose coins upon being damaged. Coins are used to play minigames to earn treasures, the more coins that are used, the easier the minigames will be.

Wario Land 3
Wario no longer drops coins when he is hurt in this game. Coins also are only found by destroying blocks, they are no longer found out in the open or by defeating enemies. The only purpose of coins is to pay to play the golf minigame which is required to unlock certain areas.

10 Gold Coin
Like with the previous section, the name "10 Gold Coin" is only used in Super Mario Land 3 : Wario Land, however we will use it to refer to any coins worth ten coins in the series.

Super Mario Land 3 : Wario Land
If the B button is pressed while the Up button is being held, ten coins will be taken from Wario's coin count for that level and he will be holding a 10 Gold Coin in his hand. This coin can be used as a weapon, used to activate checkpoints, used to open the door at the end of many levels, or collected to regain the ten coins lost in the process. When a boss is killed, it will drop many 10 Gold Coins in addition to regular coins. If an enemy is killed by a Pouncer, it will also drop a 10 Gold Coin.

Wario Land II
10 Gold Coins were redesigned in Wario Land II to be large coins with an image of Wario's head on them. They are only found in secret rooms, and in hard to access areas.

Colored Coins
Coins found only in Wario Land 3 and Wario Land 4. They are worth a varying amount of coins, depending on the game.

Wario Land 3
Colored coins will rarely appear in place of 1 Gold Coins when blocks are broken. They are all worth 10 coins, and the color is determined by whatever key Wario is closest to.
