Early 1970’s. A coin is borrowed from the audience and marked so it can be identified. The coin is placed into a plastic round box and then placed under a handkerchief. The spectator then holds the box through the handkerchief and to shake it to prove the coin is still there.
An identical box is removed from the Magician’s pocket and placed on the table. The original box is now opened and the coin is no longer there, shake the box from the pocket and a coin is heard. Not only that but once the box is opened it is revealed to be 4 nested boxes getting smaller and smaller until the last one is just the size of the coin and the coin is the original marked one.
