Dragon Coin

A Dragon Coin is a large coin that first appears in Super Mario World. It has a picture of a Yoshi's head imprinted on it.

Super Mario World
In Super Mario World, there are at least five Dragon Coins littered around most levels (some levels, such as castles, Ghost Houses, and fortresses, have no Dragon Coins in the original SNES version). Collecting each one makes a unique sound effect, and it is also counted as one coin. The first four coins collected in the game give 1,000, 2,000, 4,000, and 8,000 points, respectively; collecting five of them awards the player an extra life. Yoshi's Wings can be used to access certain auto-scrolling Coin Heavens, where five Dragon Coins can be found.

On rare occasions, one may encounter six or more Dragon Coins in a single level; every Dragon Coin after the fifth will also award an extra life. In these levels, going through a Warp Pipe to a new area causes all remaining Dragon Coins to disappear if Mario or Luigi has already collected at least five of them, making the remaining ones unobtainable. Chocolate Secret is unique, as it contains only one Dragon Coin in the SNES version of Super Mario World for unknown reasons.

Super Mario World: Super Mario Advance 2
In the Game Boy Advance port of Super Mario World, Super Mario World: Super Mario Advance 2, Dragon Coins have a slightly bigger role. They now appear in levels that did not originally have them, and the number of Dragon Coins acquired is recorded on a menu. If the player collects them all, a cutscene will play, showing all of the collected Dragon Coins falling from the sky and being stacked together; afterwards, a giant Dragon Coin appears, and Yoshi eats it and lays an egg, which hatches into a giant coin with Princess Peach's face, resulting in all of the Dragon Coins in the game having Peach's face imprinted on them instead of Yoshi's.

In the Nintendo Power Advance guide, the symbol for the Dragon Coins denoting where they are located in a level is drawn with a three-tined fork instead of Yoshi's or Peach's likeness.

The sound effect for obtaining a Dragon Coin is the same as the one used in Super Mario Advance for collecting Advance Coins. In New Super Mario Bros., this sound effect is used for Star Coins and is internally labeled as "SE_OBJ_GET_DRAGON_COIN," suggesting that Star Coins replaced Dragon Coins in the final game.

In Game & Watch Gallery 4, a Dragon Coin is used to represent five KOs in the Modern version of Boxing.

WarioWare: Get It Together!
In WarioWare: Get It Together!, Dragon Coins appear in the Super Mario World microgame. Collecting them is not necessary to complete the microgame and has no real effect on gameplay, although the "Dragon Coin Collection" mission requires the player to collect at least four Dragon Coins in all three levels while playing as Jimmy T.

The Super Mario Bros. Movie
In The Super Mario Bros. Movie, a display box containing a Dragon Coin with the same appearance as its Super Mario World sprite can be seen in the antiques shop.

Super Mario World 2: Yoshi's Island
Dragon Coins were originally going to appear in Super Mario World 2: Yoshi's Island, where they were going to be a currency along with regular coins for some of the Bonus Challenges. They were possibly replaced by flowers. The sprite for them was completely removed from the Game Boy Advance port, Yoshi's Island: Super Mario Advance 3.

Trivia

 * Most of the games in the Yoshi franchise such as Yoshi's Safari, Super Mario World 2: Yoshi's Island, Yoshi's Island DS, and Yoshi's New Island feature coins with a Yoshi's head on them rather than the normal coin design. The coins in Yoshi's Crafted World feature a depiction of a Yoshi's Egg instead; however, the larger 10 Coins depict Yoshi's head, similar to Dragon Coins.
 * The Plessie Medals found in the Bowser's Fury campaign of Super Mario 3D World + Bowser's Fury resemble Dragon Coins.
