What about that penny you recently got in change or plucked from the sidewalk? Could it be the same one your grandfather traded for a gumball while vacationing in California…30 years ago? How did it end up with you? And what about the people from the different places and times who once saved, spent, tossed or dropped this penny? Could it be the same penny that a teenage rock star wannabe used as a guitar pick before a curious toddler swallowed it after a dreamy-eyed girl threw it in a wishing well?
