Let's go over the thumb palm, another wonderful coin concealment. Take a look. Showing the left hand empty, then you're able to pluck a coin out of the air.
Unlike the classic palm which is held right here, the thumb palm is where the coin is clipped here, between your thumb and pointer finger, so from the front you cannot see the coin. You have all the freedom in the world to just move your fingers; play the piano if you'd like!
To produce the coin, have the coin in your thumb clip and show the left hand empty. Turn your left hand over, take the pinchers, they come in and pinch the coin from the audience view. That coin is clipped now, the hand moves down and produce and show the coin.
So in real time, the hand is shown empty; front and back. Clip, or pinched, and then exposed. And now you have a coin miracle.
