I watched John Cornelius's Fickle Nickel on Michael Ammar's DVD classic renditions vol 2. In my opinion it is the only valuable part of the work. It was truely a beautiful trick! Quote from the description of this trick: When John Cornelius fist showed this at a convention it fooled every including Dai Vernon. The best thing about the Fickle Nickle is that it is done without sleight of hand!
