You start out with two hands and a little bit of magic. You just need to squeeze your fist hard enough and poof! A coin appears right smack in the middle of your palm. That's not enough, though! Just reach over to the elbow and poof! Another coin materializes out of thin air. You touch the opposite elbow to the same effect. Once you've uncovered all the missing coins, you'll need some more magic to return them... a magic wand should do the trick.
