This is a mini version of the classic Sucker Box effect.  Normally a die is placed inside a large box and visibly slide from side to side with the magician claiming that it has vanished by only opening the door at the opposite end until finally all doors are opened, and the die has gone.

In this version a coin (1/2 dollar, £2, 2 Euro) is placed inside the box and the doors are closed.  The performer claims to have made the coin vanish and to prove this they open the door to show that it is not where it was.  Unfortunately for the performer the audience can see the coin roll between the two doors.  After much back and forth with the performer rolling the coin to the opposite side and then opening the door to show it has vanished, both doors are opened, and the coin has indeed vanished.

Very easy to perform
