In 1957, an amateur archaeologist working at a Native American site in Maine discovered a perplexing treasure: a 900-year-old silver Norse coin that dated to the late Viking Age (A.D. 793 to 1066).
The artifact, sometimes called the "Maine Penny," is now in the Maine State Museum. Its discovery has raised a number of questions — mainly, how did it get there, and does its presence in Maine mean the Viking reached the Pine Tree State?
