Hidden Coin

Dash Coins are special types of coins that have only been seen in New Super Mario Bros., New Super Mario Bros. Wii, New Super Mario Bros. 2 and New Super Mario Bros. U. Dash Coins are somewhat rare, and only appear in a few levels.

Dash Coins first appear as an outline of a Coin; if Mario or another character passes through the outline, it will then turn into a regular coin.
