In the spring of 1969 and 1970, a number of joined square plaque-shaped coins were found in Chu tombs in modern-day Anhui province. These pure gold coins were legal tender in the Kingdom of Chu where they were used for large transactions. Each is stamped with two characters, either 陳爰, or 郢爰, 郢, Ying, being the capital of Chu and the place where the coins were produced. These square coins were produced in plates or sheets of multiple pieces from which they were cut out according to the weight of the gold needed for an individual transaction.Most of these plaques are impressed with characters, unlike the current lot, which is embossed. A similarly embossed plaque with the same characters is found in the China Numismatic Museum, accessed online via Wikipedia, file name: Yingyuan_Gold_in_China_Numismatic_Museum.jpg.
