A resident from the northern port city of Hai Phong has found a huge jar containing coins that could date back to the 18th century.
Do Xuan Trung, deputy director of Hai Phong Museum, on Thursday told VietNamNet that 24 kilograms of the coins are being kept at the museum for further examination as they were buried in mud for a long time and thus gotten stuck together.
Initial studies show the coins belonged to the Canh Hung dynasty of mid-18th century and Gia Long dynasty in late 19th century.
Some also belonged to China's Qianlong dynasty in the 18th century and Kangxi dynasty in the 17th and 18th centuries, Trung said.
The coins were found by Nguyen Van Bay when he was working on his pond on the previous Saturday.
He found the coins in a terracotta jar with sophisticated patterns.
