A Cape Cod man stumbled upon a valuable keepsake that was lost on a beach 47 years ago. Jim Wirth hunts for lost treasures. He sweeps beaches and listens for his metal detector to go off. On a July morning, he found something special — a class ring from Manhattan College, Class of 1969. His chance find did not take him to a pawn shop. Instead, it set him off on a mission to find its owner. The name engraved inside was Patrick O'Hagan. His major on the side was "EE," for electrical engineering.
