This is a suspected Ban Liang coin, possibly minted by the state of Qin during the Warring States period. The Ban Liang currency system originated in the Warring States period and remained in use through the Qin state and early Western Han dynasty until it was eventually replaced by the Wu Zhu coin. Its characteristic round shape with a square hole set the standard for Chinese coinage, influencing the design of coins in subsequent dynasties until the 20th century, when European-style mechanical minting replaced traditional casting methods.

The coin follows the typical square-holed design, with a patina of green encrustation covering its surface. It is made of bronze.

On the obverse side of the coin, the characters “半兩” (Ban Liang) are inscribed in seal script, a style commonly used on bronze artefacts during the Warring States period. Notably, the character “兩” has been modified, with the two “人” (ren) radicals reduced to a single one. The reverse side of the coin is blank, with no inscriptions or decorative elements.

The Ban Liang established the fundamental round shape with a square hole, which influenced the design of Chinese coinage in subsequent dynasties. This form persisted as the standard monetary design in China until the 20th century, when it was ultimately supplanted by European-style mechanised minting techniques.

The Ban Liang was a round coin used as currency within the State of Qin during the reign of King Huiwen of Qin in the Warring States period. Following the unification of China in 221 BC by Qin Shi Huang, the Ban Liang became the standard currency throughout the empire. It remained in circulation until the reign of Emperor Wu of the Western Han Dynasty, when it was eventually replaced by the Wu Zhu coin.

這是一枚疑似戰國時代秦國鑄造的半兩錢幣。半兩是自戰國時代以來，從秦國一路延伸使用到西漢遭到五銖錢取代的錢幣類別，其奠定的圓形方孔影響後續中國各個朝代的錢幣造型，直到公元20世紀遭到歐式機械鑄幣取代為止。

錢幣形制為典型的方孔錢，通體為綠色的包漿覆蓋，材質為青銅。

錢幣正面的右側和左側，分別以戰國時代流行於青銅器上的篆書鐫刻「半兩」二字，「兩」裡面的兩個「人」字被省略成一個。錢幣背面為光背，沒有任何文字或圖案。錢幣背面為光背，沒有任何文字或圖案。

半兩為戰國時代秦惠文王統治時期，於秦國境內流通的圓形貨幣。隨著公元前221年，秦始皇建立中國歷史上第一個統一的王朝，半兩也為通行於全國的貨幣直到西漢武帝之際，方才為五銖錢取代。
