One of the best. Simple and a real shocker.

Our brilliant Chinese coin, a half dollar, a playing card and a black wallet are shown.
Take the half dollar from the wallet and place it on the back of your spectators hand,
that is place on top of the wallet and pressing on the Chinese coin that is inside.
Cover the half dollar for only a second with the playing card.
The Chinese coin is now on the back of your spectators hand and the half dollar is in the wallet.

No skill required the coins do all the work!
