e-Coin
e-Coins are a rare type of coins found only in World-e of Super Mario Advance 4: Super Mario Bros. 3. Fairly well hidden, only three of the eleven levels released outside of Japan have e-Coins.
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 each e-Coin shows the e-Reader "e". Each e-Coin can only be collected once by Mario or Luigi before going on display in World-e's castle, where they reside in individual frames with their level of origin underneath.
There are eight frames and eight e-Coins, but they appear to serve no purpose other than bragging rights; this said, visiting the castle reveals a small display in the top-left corner reading "1F".
