Coin (Wario Land 4)

Four different kinds of coins can be found in the Game Boy Advance game Wario Land 4. If Wario opens a Jewel Piece Box, a Gold Coin will appear along with collecting a jewel piece. They can also be obtained from Health and a CD case. Wario can also retrieve Gold Coins by destroying a Pinball Block. Silver Coins can be obtained by defeating powerful enemies. Other, less valuable coins (like the Bronze Coin and small coin) can be obtained by defeating minor enemies and breaking blocks. Coins can also be obtained from a Money Flower. The blue and red coins that sit unmoving in the air are called Blue Crystals and Red Crystals. All coins collected are put to the side after completing a level and can be spent later in the Mini-Game Shop, where Wario can play one of three minigames. If he gets a certain score in any minigame, he will be awarded a medal, which can be used to purchase items from the Item Shop to assist him in defeating a boss.
