They say to never bet a man at his own trick. Well, this is no exception. You show two coins, a copper Mexican centavo, and a silver American Half-Dollar. The Half-Dollar is slightly bigger than the other. The two are openly placed into a spectator?s hand and then go behind their back. You then ‘bet’ them they CANNOT hand you the smaller copper coin right away. When they try, they find a quarter instead! The copper coin has vanished and has reappeared in an impossible location.
