Magic Coin Nested Box......$2.50

Here's a really nice and effective coin mystery using a spectator's
borrowed and marked quarter.  The performer takes the coin and
places it into his pocket for just a second and immediately brings out
a round colorful plastic box, which is handed to the spectator.  

The spectator is asked to open the box and when they do they
discover another box.  This second box is opened to find a third box.  
When the third box is opened yet another box is discovered.  Finally
when the fourth box is opened the spectator discovers their very own
marked quarter!  How the magician was able to introduce their coin
into the innermost box in a matter of seconds is a very perplexing little
mystery.

In a more advanced routine, the magician can actually make the
spectator's coin vanish first, and then remove the set of nesting boxes
from the pocket and proceed as described above.
