Advance Coin

Advance Coins, also known as Ace Coins or A-Coins, are special coins that appear exclusively in Super Mario Advance 4: Super Mario Bros. 3. They appear only in the new World-e levels. They are similar to Ace Coins in appearance, except that they are yellow. Unlike Ace Coins, they spin before being collected.

Levels have anywhere from one to five Advance Coins in them. If Mario or Luigi collects all the Advance Coins in a level, he will earn an extra life, similar to a Dragon Coin or Ace Coin. There are 147 Advance Coins in total throughout the game.

If the player accumulates enough Advance Coins, they can enter any of three special World-e Toad Houses, where they can play a special mini-game. The player must collect 30 Advance Coins for the Blue Mushroom House, 50 for the Red Mushroom House, and 80 for the Orange Mushroom House. However, because a limited number of levels were released outside Japan, non-Japanese gamers will be able to collect only 49 Advance Coins and will therefore be unable to gather enough Advance Coins needed to enter the final two Toad Houses, except in the Virtual Console versions of the game released on Wii U, where all the World-e levels are available by default in all regions.
