2. Basic unit

there were many monetary units in ancient China, which were different from Dynasty to Dynasty, especially before Qin and Han Dynasties. Only three basic units are discussed here:

Yiwen coin (i.e. a standard copper coin with square hole)

one or two silver

one or two gold

although the above units are different from Dynasty to Dynasty, there is little difference at least after Tang and Song Dynasties, so relatively stable and reliable data can be obtained<

exchange relationship

the exchange ratio of copper, silver and gold, just like the current foreign exchange price, often changes, unlike the one yuan equals 100 points<

according to the following description:

"the price ratio of gold and silver rose from 1:8 around 1600 to 1:10 in the middle and late 20th century, and doubled to 1:20 by the end of the 18th century."

it can be seen that 1 liang of gold can be exchanged for 8 ~ 11 liang of silver< In the early years of Daoguang, one or two pieces of silver were exchanged for a crane, that is, one thousand Wen; By the time of the Opium War in the 20th year of Daoguang, one or two silver coins could be exchanged for 16700 RMB. Since Xianfeng, the price of silver has soared, and one or two silver coins can be exchanged for as much as two thousand two hundred and three hundred Wen. "

it can be seen that under normal circumstances, one liang of silver can be exchanged for 1000-1500 Wen of copper coins. In ancient times, one Guan coin or one Diao coin is 1000 Wen

metal price

since the currency made of gold, silver and copper has value itself, and theoretically, the value of currency should be equal to the price of metal, we can answer the question of "how much is one or two silver" through the current price of metal

Kaiyuan Tongbao Tongqian of Tang Dynasty has a diameter of 8 points, 10 pieces weigh 1 liang, and Qianwen weighs 6 Jin and 4 liang; During the reign of emperor Shun of the Qing Dynasty, each copper coin weighed one and two cents and five percent, and then increased to one and four cents, which meant that each thousand Wen weighed eight Jin and twelve Liang. Although the ancient "two" weight units are different, they are about 40 grams, while the "Jin" is about 700 grams. The average weight of each coin is 5g< At present, the price of gold, silver and copper (RMB) is as follows:

Gold: 100 yuan / g

silver: 2 yuan / g

brass: 0.02 yuan / g

the calculation result is as follows:

1 liang Gold: about 4000 yuan

1 liang silver: about 80 yuan

1 copper coin (1 Wen coin): about 0.1 yuan

grain price

< br />Many Historical Monographs directly measure the monetary relationship through the grain price. Although it is not accurate and objective to consider the grain price alone, it should be an extremely important reference. Xiaolin found the following record on the Internet:

"nine cents and five cents for shangmi (stone)<

Zhong rice (stone) is nine cents and six cents and eight cents<

What's the price of Baimi (stone)

white? In the first half of the 15th year of the reign of Emperor Guangxu, the grain prices of shuntianfu, damingfu and xuanhuafu in Zhili Province were calculated on the basis of millet, sorghum and corn, with an average of one hundred twenty-four cents and six cents per warehouse stone, according to the records of the military aircraft Department of the Qing Dynasty

according to the calculation of 1 stone = 100 Jin = 70 kg, and the grain price is 2 yuan / kg, the following average value can be obtained:

1 two silver: about 170 yuan

1 copper coin (1 coin): about 0.2 yuan

conclusion

according to the above calculation, considering that

1 the price of gold is more stable than others, We should pay attention to

2 now silver has been used as an instrial proct, so the reference value of silver price is low

3 e to the rapid development of agricultural technology, the relative price of grain is much cheaper than that in ancient times

4 respect the exchange ratio in ancient times

5 rounding up, which is convenient for conversion and perceptual knowledge establishment

therefore, The author suggests that the following conversion system should be adopted when meeting ancient currency units in the future:

1 liang of gold = RMB 2000 yuan = 10 liang of silver

1 liang of silver = RMB 200 yuan = 1000 Wen Yuan = 1 Guan (Diao) Qian

1 Wen Qian = RMB 0.2 yuan

in addition: 1 Shi Mi = 1 liang of silver
