1 Cash - Duanping Yuanbao, with year

Duanping was the reign title of Emperor Lizong of the Southern Song dynasty, and 1234 marks the final year of the Jin dynasty's collapse under Mongol pressure — a catastrophic convergence that effectively ended centuries of northern Chinese coinage traditions. Southern Song mints were simultaneously managing military finance and refugee monetary demand as the Jin frontier dissolved. The "with year" designation on this cash indicates the cyclical date inscription, a practice that aids attribution but introduces significant die variety complexity within the Hartill 17.721 grouping.
