Thien Phu Nguyen Bao (in mixed scripts) / Blank. 22mm, 2.00 grams. Toda 7; Barker -.

Toda attributed this rare small type to the Ly dynasty Emperor Nhan Tong (1072-1128), but such an early attribution does not seem likely, and it is more likely, in our opinion, that the coin dates to the 1300-1400's.

The coins of the Vietnamese Kings imitated Chinese coins. The official issues were often heavier than the Chinese coins and with somewhat cruder calligraphy. Many local imitative issues circulated along with the official coins. This large copper coin is an official issue coin.
