Hidden Coin

Dash Coins are special types of coins that have only been seen in the Super Mario series, specifically New Super Mario Bros., the Wii version and the 3DS game. At first glance, Dash Coins appear to be an outline of a Coin. In this state, they cannot be collected. However, if Mario or another character are to make contact with the coin in any way, it will turn into a regular coin. Dash Coins are somewhat rare and only appear in a few levels, yet they still are worth the same as regular Coins.
