 Qin State coins were inscribed with the Chinese characters "Zhu zhong yi liang" (珠重一兩, "pearls (round coins) heavy one liang"), which might have been kind of lot numbers, while other early State of Qin weighed half a tael or one "zi" {中冖田} (甾, 錙), which was six "zhu".1 tael coins tended to have a round centre hole, and half tael coins a square hole.The reverse side of all of these early round coins were blank.
