Vanishirt by Alessandro Criscione
In 2011 I had thought of closing one of my "one coin" routines with this effect. 

I thought to myself, what would be fun Today I can say I found something fun and amazing... that something is "Vanishirt." 

Show a coin in your hand. While holding it, place your hand in the fold of your shirt. Remove your hand and show it empty. Keeping your empty hand in view, your other hand unfolds your shirt to reveal that the coin has vanished! 

Download the video and learn this amazing effect - hope you enjoy!
