"I hollered, 'Albert look here what I found!' And we looked at it, it's a 1736 silver coin," said Jonathan Bowman.
Pictures and measurements of the coin have been sent to the Smithsonian to see if the coin really is a 1736 French coin.
If the coin is authentic, the rare item dates back to the time of King Louis XV. He was king of France during the French and Indian War, when French military men were in the United States.
