This paper delineates the developmental trajectory of overlapping casting into three distinct stages:primary, intermediate, and advanced. During the Han Dynasty, this evolution unfolded in two phases: primary and intermediate. The primary stage transitioned into the intermediate stage during the middle to late Western Han Dynasty, marked by the advent of Shanglin Sanguan casting and block pattern casting money during the Xinmang period. By the third reform under Wang Mang's reign, the primary overlapping casting had progressed to intermediate overlapping casting. Building upon this framework, the paper delves into the age and characteristics of the Wuzhu overlapping casting model and its associated site, which have sparked considerable debate within academic circles. It suggests that their age likely falls between the period of Gengshi and the 17th year of Emperor Jianwu, representing a period when central authority fluctuated in its control over currency casting, leading to both centralized and local casting practices.
