1 Jin Anzang

Western Zhou as a distinct state was extinguished by Qin in 256 BC, which compresses the actual production window for this type considerably. The Qin annexation was administrative as much as military — the last Zhou ruler surrendered without significant resistance, handing over his ancestral temple vessels along with territorial control. Jin spade money of this weight class circulated across the Wei River basin economy primarily as unit currency in grain and textile transactions, not tax payments, which were increasingly denominated in Qin bronze by the late period.
