SEOUL, KOREA—U.S. Immigration and Customs Enforcement officials have returned a Hojo currency plate to the government of South Korea. The late nineteenth-century plate is one of only three in existence, and it is thought to have been looted from the Deoksu Palace in Seoul by an American serviceman during the Korean War. Homeland Security Investigations special agents seized the plate in New York from a collector who purchased it from an auction house. “Our intention from the very beginning was to ensure the item’s expeditious return to its rightful owners,” said William Hayes, acting special agent in charge of Homeland Security Investigations in Detroit.
