Brass Nest of Boxes

A coin is borrowed and marked by the spectator. The magician places the coin into the folds of a handkerchief and gives it to a spectator to hold. The magician then reaches into his pocket and removes a small metal box which is placed on the table. On the spectator's command the handkerchief is shaken out revealing the coin has vanished. The metal box is opened revealing a smaller box inside. Inside the next box is another box, then finally a smaller box. When the smallest box is opened, the marked coin is found inside!
