A local resident in Loc Ninh commune discovered the jar when he was digging earth to build the foundation for his new house.
The brown 35 cm high terracotta jar contains seven round copper coins with square holes in the middle. The coins, all rusty, are of different sizes and thickness and have sophisticated carved patterns.
Initial studies shows the coins date back thousand years ago. Among them, five are believed to be from Chinese Bei Song dynasty in the 10th – 11th centuries. Another one is from Chinese Ming dynasty (1402 – 1424).
There is a Vietnamese coin issued under the reign of King Le Thanh Tong (1460 – 1497) with clear and fine decorative pattern.
