The Maine Penny, found in Blue Hill, Maine. An 11th century Norse coin found in an American Indian shell midden. Over 20,000 objects were found over a 15-year period at the Goddard site in Blue Hill. The sole non-Native artifact was the coin.[3] One hypothesis is that it may have been brought to the site from a Viking settlement in Newfoundland by seagoing Native Americans.
