Jack Dean’s Stagecraft Magic: The Engraved Medallion

Well made effect.  Spectators choose three random numbers (they truly are).  The magician writes them down in a small notepad and hand them to the spectator to hold. He then recounts what jus happend and immediately removes  a small box from his pocket and hands it to the spectator..  The box is opened and inside is found a beautiful medallion.  The spectator is asked to turn it over and on the back of the medallion is an  engraving of the chosen number. Complete with original instructions and all accessories.
