Puzzles: Money Maze

This is what you call the money maze. It is sort of a coin bank (though I’m putting a bill) wherein you have to solve first the puzzle/maze before it actually opens. A small metal sphere is made to go through the maze and at the end of it; the metal sphere passes through the lock that is connected to a spring that ultimately opens the coin bank.

I was actually planning to give it to somebody, I want to give him a headache before receiving his reward, but decided to keep it for myself. It’s one of the unique and rare finds I had.
