"Half two" money is inside the outer ring, with no inner and outer contours and a flat back; The word "Banliang" in seal script is listed on both sides of the perforation, and Qian Wen is raised, which is said to have been created by Prime Minister Lisi. Strict layout, overlapping strokes, elegant and vigorous. The "half-two" money circle is square, with a circle outside, rigid and flexible, and dynamic and static combination, reaching the highest level of symmetry and balance.
Qin unified China and unified the currency, stipulating that gold was the superior currency, with the unit of "one" (20 Liang or 24 Liang); Copper is the next coin, and the unit is "half two". During the Warring States and Qin Dynasties, half a tael of money was cast. First it was money, then it was changed to square hole round money.
After the reunification of the Qin Dynasty, China was promoted to half a penny. Since then, the currency form of square hole round notes has been used for more than two thousand years. Today, Qin Banliang's money varies in size, with a diameter of 3.2-3.4 cm and a weight of about 8 grams. Qian Wen is long and narrow, slightly curved. No inner and outer Guo, flat back. Some of them weigh more than 10 g, or even more than 20 g, which is still the "when white" contained in Suoyin.
Extended data:
Qin Shihuang unified the currency mainly in two ways: first, the state unified the coinage, severely punished private coinage, and held the right to manufacture the currency in the hands of the state. The second is to unify the two currencies, namely, the upper currency gold and the lower currency copper. The change of gold is based on "Iraq", and one Iraq is 22 Liang. Copper coins take "half Liang" as the unit, and the word "half Liang" is obviously cast in gold coins.
Copper coins are shaped like square holes, commonly known as "Qin Banliang". Pearl jade, tortoise shell, silver and tin, which were once popular in six countries, can no longer be used as currency. Speaking of the Qin Dynasty, China's currency was second-class; Gold is named after Yan, and it is a coin; Copper coins, commonly known as half a tael, are as heavy as the text, and are the next coins. Jade beads, tortoiseshell, silver and tin are ornaments, not coins.
