《史记·八书·平准书》
流行的钱既已很多，下令天下，凡不是三官铸造的钱币不许使用，诸郡国以前铸造的钱币全都销毁，把销钱得到的铜上缴三官。
钱既多，而令天下非三官钱不得行，诸郡国所前铸钱皆废销之，输其铜三官。
Since there were already many coins in circulation, the emperor ordered that any coins not cast by the three officials would not be allowed to be used, and that all coins previously cast by all the prefectures and states would be destroyed, and the copper from the abolition of money would be handed over to the three officials.
