| Additional information |
The Thiên Tư Thông Bảo coinage belongs to the reign of Lý Cao Tông, who ascended the throne as a child and presided over a court increasingly destabilized by aristocratic factionalism and peasant uprisings. Private casting of cash coins was a persistent problem throughout the Lý dynasty, and the question of whether this issue originated from an authorized mint or a private foundry remains unresolved among specialists — Toda catalogued it with deliberate ambiguity.
