EFFECT
3 Brass caps a £1 coin and 2 - 5p coins are shown, the 3 coins are covered with the caps and are mixed the spectator is invited to keep track of the £1 coin. After failing you make it easy you give them a penny to place on the cap with the £1 coin Then they are mixed and they fail again. To make it easier 1 cap and a 5p is removed and placed to one side; the 2 remaining caps are mixed after placing the penny on the cap covering £1 coin.

In a mind blowing finale the 2 caps you mixed now cover the 2 - 5p coins and the£1 coin is now under the cap you placed to one side earlier.
