Disappearing Coin

Effect: A coin disappears from your hand in spite of the fact that several people check it is there.

Secret: Show the coin on the palm of your hand and cover it with a handkerchief. Go to several people and ask them to feel the coin under the handkerchief. The last person you approach is (unbeknown to the rest of the audience) your secret assistant. He pretends to feel the coin but actually takes it off your palm. You can now pull the handkerchief away with a flourish and your hands are shown completely empty. The coin has disappeared.
