With this clever prop the magician can multiply the number of coins in a spectator's hand with no sleight of hand.
Simply slide the coins off the tray and the work is done!
The basic routine is as follows: Six coins are counted out onto the tray, and the spectator chooses one.
From across the stage, you pour the tray into another spectator's hands, and he closes his fist, holding them tight.
Now you make the spectator’s coin vanish (using your favourite method), and the second person opens his hand to find all six coins!
