Spike thru Coin

You have seen a magician piercing a lady inside the cupboard with many swords. Here is a pocket sized version of that trick.

A coin is kept inside a small round box with holes on the top lid and the bottom base.

Five nails are passed through the box through the holes. You can visibly see the holes going through the lid and passing out through the bottom.

Yet when you remove the nails and open the box, the coin is unharmed. Your spectators will rub their eyes in disbelief!

 Easy to do. No Practice required.
