Legendary Matchbox Trick

The magician borrows a coin from a volunteer in the audience. The volunteer marks their coin, the magician takes the coin and immediately reveals a large matchbox sealed with rubber bands. The spectator is asked to remove the rubber bands and open the matchbox. Inside is a second matchbox bound by more rubber bands. These are removed and the box is opened revealing a small bag also sealed by a rubber band. The bag is opened revealing the marked coin!
