E-Coin

e-Coins are rare types of coins found only in World-e of Super Mario Advance 4: Super Mario Bros. 3. Only three of the eleven levels that were released outside of Japan actually have their own e-Coin. e-Coins are fairly well hidden. Little is known about the e-Coins, except that each one is unique and features a different image on one side. The other side of an e-Coin has the letter "e" on it. Each e-Coin can only be collected once before going on display in World-e's castle. They appear to serve no purpose other than bragging rights.
