Magnetic Silver & Copper: English Penny
by Johnson Products

A Half Dollar and English Penny pieces are given to spectator to hold behind his back. Magician asks for Half Dollar which spectator hands him. Then you ask for the English Penny. When spectator opens his hand he finds that it has changed into a Quarter and he can examine both coins to his heart?s content.

Again, the only reason this is such a straight-forward miracle is because of the precision machining that has gone into the coin. Here?s one you?ll really use.

Complete with routine.
