Twenty One Cent Trick by Empire Magic

Effect: Four coins are shown on a table or desk. They are two nickels, a penny and a dime. The total value is 21 cents. The magician picks up one coin at a time and places them in the palm of his left hand. He counts the value of each coin as it is placed into the palm, until all coins, total of 21 cents are in the palm. He now removes a nickel from his left hand and places it into his right hand pocket. He closes his left hand over the "remaining" coins and asks how much is left. The answer should be 16 cents. However, when the fist is opened, the 16 cents is gone! He then removes the nickel from his pants pocket and it may be freely examined.
