If you want a good effect that will leave a lasting impression then look no further.  Made in brass.  A quarter is marked and placed into a brass box. The lid is placed on top and the box placed aside.  Magician then picks up a brass box that is locked with a pin through it, that has been sitting out in the open at all times.  The lock is unlocked, the lid removed and inside is the marked quarter.  The coin box on the table is then picked up, opened, and inside in place of the marked quarter are five dimes!  No coins supplied.  The previous is a suggested routine but the instructions included give a routine where a key to the lock is found within making for a different routine.  Includes 2 pages of illustrated instructions. 

Condition some spotting of tarnish on brass, otherwise mechanically fine.
