There are abundant types of Ban Liang coin-minting models and molds found in archeology,not only can be divided into master patterns and casting molds,but also three types of materials:pottery,stone and metal.Through the study of Ban Liang coin-minting models,it can be seen that the casting process of Ban Liang coins is the coin casting with hard molds,which has experienced the casting process of'ancestral patterns → master patterns → casting molds',and the different functions and materials of Ban Liang coins are also different in the casting process.The coin casting with hard molds includes vertical coin casting with block molds and coin casting with overlaped pottery molds.While the Ban Liang coin casting is mainly based on the vertical coin casting with block molds,the coin casting with overlaped pottery molds also appeared in the Western Han Dynasty,which is an important manifestation of the development of China's coin casting process.
