This little miracle has stood the test of time.  The magician borrows a coin and has it signed by a spectator, the coin is caused to vanish (purchaser must already know a method for this).  A matchbox is placed onto the table and the spectator is invited to open it - inside is another, but smaller matchbox.  This in turn is opened - inside is a small cloth bag sealed by a rubber band, this is opened to reveal the signed coin.

A super little close up magic trick that can be ready to perform at any time.

Good magic that is easy to do.
