Chinese boxes

A wonderful trick. You borrow a coin and let him mark with a marker. You covered the coin with a handkerchief and put a small locked box on the table.
The tissue is removed and the coin had disappeared!

The magician then leave the box by opening the viewer and there appears a second sealed box to sit in. That box is opened again and it turns out right ... another box! This goes on for a bit, but in the last case still comes to everyone's amazement the marked currency.

You will receive the boxes, and the explanation gimmick to make the coin disappear
