 As the general populace found inconvenience in using the heavy Ban Liang coins the Han government allowed for the private production of smaller Ban Liang coins known as "elm seed" () Ban Liang coins.The design of the Ban Liang coins would also change as Han dynasty Ban Liangs would later add rims while all Qin dynasty versions were rimless.In the year 186 BC, or the 5th year of Empress Lü, the government officially set the weight of the Ban Liang at 8 "zhu" and the inscription was now written in clerical script.
