About this source
What it is
This is a bronze Ban Liang coin cast during the early Han dynasty, with a square central hole typical of Chinese cash coins. Ban Liang coins continued in use from the Qin dynasty into the Han, before being replaced by Wu Zhu coins later on. This particular coin dates to a period after Gaozu, during the regency of Empress Dowager Lü Zhi.
Why it matters
Emperor Gaozu allowed lighter versions of the Ban Liang coin to be cast instead of the heavier coins used under the Qin, loosening the strict economic controls of the previous dynasty. This small object reflects a real policy choice made at the founding of the Han dynasty, showing how Gaozu tried to ease the burdens of Qin rule on ordinary people.
