Dirty Money

I had an interestingly bizarre though yesterday as I was flushing the toilet. If you accidentally dropped some change into the toilet at home (where no one else would see) after a #2, how much would it have to be for you to stick your hand in to get it? A quarter? A loonie? A toonie?

Obviously, the easy way of doing it would be to get something long to extract the coin(s). But let's assume for the moment you don't have anything but your bare hands, which you're permitted to wash afterwards.
