The quote from the Council of directors of Education in the city of Uruma, the Japan Times reports that the four copper coins are believed to be from the third to the fourth century.

X-ray analysis of the coins has apparently revealed the image of Emperor Constantine I, and a soldier with a spear. Each coin measures 0.6 cm 0.8 cm in diameter, according to the report.

Uruma the Board of Education noted that the Okinawa’s trade with China and Southeast Asia was thriving during the castle’s existence and described the coins as “valuable historical material to suggest a link between Okinawa and the Western world.”
