在秦统一六国之前，各国钱币的形状不一，如铲币、刀币、环钱等，且只能在各自统辖的范围内流通；秦始皇在统一六国后，确定统一法律、度量衡、货币和文字，废止了战国后期六国旧钱，在战国秦半两钱的基础上加以改进，圆形方孔的秦半两钱在全国通行，结束了我国古代货币形状各异、重量悬殊的杂乱状态。

“秦半两”的出现，标志着秦始皇在货币上的大一统，还标志着中国古代钱币的初步成熟，是中国货币发展过程中的一个里程碑，并影响到相邻国家和地区，具有非凡的历史意义。“秦半两”奠定“圆形方孔”的古钱币造型。“圆形方孔”钱币成为古代中国货币的基本形式，贯穿中国封建社会，沿用了两千多年。“秦半两”青铜币以“圆形方孔”为货币造型，方孔代表地方，外圆代表天圆，“圆形方孔”即象征着古代天圆地方的宇宙观（这是一种普遍容易接受的观点。但也有人认为，圆形方孔是生产、加工的需要，是便于携带、流通和储藏的需要，在不断的实践中形成的较为科学的制式）。青铜币上的“半两”二字为小篆文字，是由秦国著名的李斯所题写；它表示每枚重为当时的半两（即十二铢），故称“半两钱”。此枚秦半两钱币为入盒钱币，包浆浑厚自然，字迹清晰，为难得一见之佳品，具有极高的历史价值与市场价值。

 

Before the unification of Qin, the coins had different shapes, such as shovel coins, knife coins, and ring money, and could only circulate within their respective jurisdiction. Qin Shihuang unified the unified laws, measures, currency and words, abolished the old money of the late Warring States Period, and improved the circulation of Qin and ended the chaos of different shapes and different weight in ancient China.

The emergence of "Qin Banpo" marked the monetary unification of Qin Shi Huang, and the initial maturity of ancient Chinese coins. It was a milestone in the development process of China's currency, and affected neighboring countries and regions, which was of extraordinary historical significance. "Qin Banpo" laid the "round square hole" of the ancient coin shape. The "round square hole" coins became the basic form of ancient Chinese currency, ran through Chinese feudal society and were used for more than 2,000 years. The bronze coin of "Qin Banpo" takes the "round square hole" as the monetary shape, the square hole represents the place, the outer circle represents the celestial circle, and the "round square hole" symbolizes the cosmic view of the ancient celestial circle (which is a generally accepted view. However, some people believe that the circular square hole is the need of production, processing, is the need for convenience to carry, circulation and storage, the more scientific system formed in continuous practice). The word "half two" on the bronze coin is a small seal script, inscribed by Li Si, a famous state of Qin; it said that each piece was then half two (twelve baht), so it was called "half two money". This Qin half 2 coins for the box of coins, the pulp is thick and natural, the handwriting is clear, is a rare good product, has a very high historical value and market value.
