Comments

These small lead pieces are imitating Kaiyuan Tongbao pieces from the Tang dynasty.

These circulated widely, with the Chu authorities fixing the rate of 1 Lead Cash to 100 Bronze Cash. These were mostly restricted to circulating within towns, and were likely cast unofficially by merchants or the people.

Tanzhou was renamed to Changsha in 927.
