NEW YORK (Reuters): A collection of ancient silver pieces forfeited during an undercover investigation into black-market coin trading in New York City was handed over to the Greek government at a ceremony, city officials said. The repatriation of the five coins dating back to 515 BC resulted from a plea agreement by a Rhode Island orthopedic surgeon and longtime coin collector who was convicted of attempted criminal possession of rare stolen coins in 2012.

‘The coins being returned to us by the New York County District Attorney are exquisite ancient artifacts that reflect Greece’s culture, history and enduring strength,’ Christos Panagopoulos, Greece’s ambassador to the United States, said in a statement.
