楚国爰金。战国时代。郢爰。 History of Chinese Currency第7页有记载，编号#1，Hartill-5.1，重量：9.1gms。刻有"郢爰"，製于今湖北省。光泽艳丽，受保护区域有轻微积土痕迹。製作时，先作有铭文的金条，再根据需要将其切成零星小块。据推测，此为从一块较大金钣分割出来的合二为一的小金块。此为中国货币史上首款形制确定的金质货币。
CHINA. State of Chu. "Yuan Jin" Gold Cube Money, ND (ca. 475-221 B.C.). Warring States Period. Graded "70" by Huaxia Coin Grading. History of Chinese Currency-pg. 7, #1; Hartill-5.1. Weight: 9.1 gms. A partial cube inscribed "Ying Yuan", made in what is now Hubei province. Bright with minor earthen deposits in the protected areas. A wholesome cut fragment with much of the inscription visible. This example was cut from larger bars which allowed for the making of small denominations, in this case, a partial cube was presumably separated from a larger set. Hartill conjectures that these stamped shapes were not meant to be specific weight units, but rather to validate the larger gold block. Historically this is China s first gold currency with a fixed shape and size.
