Listen, friends, and now you may hear
Of one magician most peculiar,
No cards, no hats, just an object of choice,
They select, and now heed their prominent voice:
"Comrades, allies, throughout all the land!
"Should I now demonstrate my sleight of hand?"
With a wave of the wrist, an action not bold,
They make their humble item worth tenfold.
Now, myself baffled, I riddle you this:
How did they do it? What is amiss?
There have been many creative answers submitted on the basis of the riddle stating 'tenfold' precisely. The riddle was intended so that 'tenfold' wasn't important to the solution could easily be replaced with 'sixfold', 'eightfold', etc.
