"Ring-pull on a Coke can" really medieval treasure

18-year-old Conor Sandford of Kilmore, Ireland believed he was picking up a soda can ring from the hole on his father's farm. What he actually found was a 12th century silver ring, "very well-preserved, and it was relatively unworn." (photo)

The ring has been declared treasure by the county coroner, although Sanford plans to donate it to the Ulster Museum. He said seeing the ring in the museum was all the reward he wanted.
