BELLINGHAM, Wash. (AP) — Authorities in Washington state have transferred dozens of ancient coins seized in 2017 at the U.S.-Canada border to the University of Washington to be studied. Homeland Security Investigations Pacific Northwest said there were 51 Greek Hellenistic and early Islamic coins. The Bellingham Herald reports that agency documents said a suspect returned to the U.S. after he was refused entry into Canada. Agents determined the suspect, who was not identified, could not prove he owned the coins. The suspect signed an agreement to abandon the coins, which were later legally forfeited to the U.S. government. The University of Washington petitioned in 2019 to the Border Patrol to donate the coins. The coins were transferred on Thursday.
