Qi was a short-lived puppet state established by the Jurchen Jin dynasty in 1130 to govern the conquered territories of northern China, with Liu Yu installed as emperor to lend a veneer of Han legitimacy to Jin occupation. The regime lasted only seven years before Jin abandoned the experiment and absorbed the territory directly in 1137. Coinage under Qi is consequently among the most compressed series in Chinese numismatics — a narrow window of just seven years producing a limited range of issues that rarely appear in Western collections.
