The form of the outer circle and the inner square of the Chinese copper coin has become a standard system since Qin Shihuang unified China, and has been used for thousands of years, containing the character and heritage of the Chinese outer circle and inner square.

After the Qin Dynasty, all kinds of round square-hole coins were minted, but they still could not solve the lack of circulating currency in the market.

With the entry of a large amount of silver into the Ming Dynasty, the ratio of Ming copper coins to silver has increased year by year.

The government, localities, and squires saw that coinage was profitable, and began to mint a large number of copper coins that cut corners to earn interest.

By the time of Chongzhen, the price of inferior copper coins to silver reached more than 5,000 copper coins to one or two silver deformed states.

Zhu Shunming vigorously developed industry and commerce, and the circulation of money became extremely frequent. Confused coin ratios, scattered silver of various colors, gold of high value that is difficult to distinguish between real and fake...... It has become a major obstacle to the flow of goods.

As Zhu Shunming's wings grew, the matter of minting coins gradually came to the agenda.

………………

In Jiu'an Town, the site of a former jade garment factory, several small machines are running non-stop under the traction of mules and horses.

"Bang Bang...... Bang Bang ......"

A large flat copper plate is placed on the machine, and the stamping die is driven by animal power, and the cycle keeps stamping up and down.

After a week of machine operation, a yellow copper coin fell to the ground.

This kind of stamped copper coin, the front of the "Chongzhen Tongbao" and the back of the "Zhu Ming Dashun" handwriting is extremely clear. There are subtle zigzag lines on the edge of copper coins, which is a unique process for stamping and pressing money, and it is absolutely impossible to make such a subtle anti-counterfeiting technique by casting.

Zhu Shunming's understanding of finance is not very deep, and he still stays at simple transactions and loans, so Zhu Shunming's financial policy is relatively conservative and stable.

In the course of economic development, the problems of inconsistent currency values, copper coins, and the complex forms and contents of gold and silver have brought great inconvenience to transactions.

Zhu Shunming was driven by commerce and passively began to mint currency.

Sun Yuanhua cast cannons on the Jiaodong Peninsula. In the process of casting cannons, Sun Yuanhua conducted a certain research on the properties of steel alloys, and manufactured steel with high hardness and suitable flexibility for stamping.

Zhu Shunming came up with a plan, and Sun Yuanhua organized personnel to develop and manufacture coin stamping dies and equipment, which were transported from Shandong to Zhu Shunming's nest in Jiu'an Town, Chengbu County, and began to secretly manufacture coins.

Coins are divided into bronze, silver, and gold coins.

There are two kinds of copper coins, one is a small copper coin, which is worth a penny; A large copper coin, when five coins, the currency is worth five cents.

The design of the silver coin follows that of the ordinary coins of later generations, and the round shape is without holes. There are two types of silver coins, one hundred and one thousand, of different sizes.

The gold coin is also round and without holes, with the words "Chongzhen Gold Coins", "One Coin" or "Five Coins" on the obverse and "Zhu Ming Da Shun" on the reverse.

Judging from the design of the coin, Zhu Shunming intended to implement the silver standard.

Two kinds of silver coins, one is worth 100 wen, and the amount is 1 penny; One currency is worth 500 wen, which is converted into five coins of silver.

Zhu Shunming fixed the ratio of copper coins to silver coins, and also fixed the ratio of silver coins to silver.

Silver coins are made from an alloy of silver, copper, tin, and other metals. For every silver coin made, Zhu Shunming can get 20% of the money interest, which is a considerable wealth.

Gold coins only correspond to gold, and a gold coin marked "one coin" can be exchanged for one real gold in "Jiu'an Qianzhuang".

The price of gold against copper and silver fluctuates with the fluctuation of the market.

The reason why Zhu Shunming did not include gold in the monetary system is that the current economic development has not yet reached the level of using gold as the standard currency.

Gold as the standard currency did not happen until a few hundred years later, when the Western world expanded and became extremely rich in wealth and goods.

Zhu Shunming also thought about printing banknotes, which was much more profitable than 20% of the money. But after a little thought, he gave up on this appealing idea.

Banknotes must be backed by the credibility of the imperial court. Was the Ming court reputable? If the Ming court is credible, the Ming treasure banknotes will not be flooded to the point that people will dislike them.

Zhu Shunming is still in the stage of accumulating strength and trying to develop, and he is far from the level of issuing banknotes.

In fact, Zhu Shunming's private production of coins of different specifications also violated the laws of the Ming Dynasty. However, during the Chongzhen period, the laws of the Ming Dynasty have been almost destroyed by many merchants, landlords, scholars, and officials. The merchants who minted coins privately did not know how much they were, and they did not see a few arrested.

………………

Zhu Shunming returned to Huangzhou from Jiangnan and immediately began to launch the shipping strategy of grain, and at the same time launched the numismatic strategy.

Although Zhu Shunming was rich and powerful, his reputation was not justified compared to the imperial court, so his promotion of coins was completely commercial, without a trace of administrative compulsion.

Overnight, all of Zhu Shunming's industries began to implement new currencies.

The introduction of the new currency coincided with the development of commerce. With little effort, the new currency was quickly recognized.

The handwriting is clear, the shape is exquisite, the copper and silver content is full, it is difficult to imitate, and the currency value is appropriate...... With many advantages, Zhu Shunming's new currency quickly became sought after by the market.

Chinese have had the habit of collecting wealth since ancient times. Large families preserve their wealth, in addition to buying land, they store a large number of copper coins, gold, silver and jewelry in the basement of their homes.

Zhu Shunming's copper coins and silver coins are so exquisite, and the back of each coin has the words "Zhu Ming Dashun", which is called "Zhu coin" by people, and has become a collection that many large families regard as wealth preservation.

On the one hand, there is a growing demand for copper and silver coins, and on the other hand, Zhu coins are being collected in large quantities and withdrawn from circulation, resulting in a shortage of suitable coins on the market.

How to let the wealth sleeping in the basement enter the circulation field is a systematic project, and only gradually and slowly let the rich people change their thinking and create practical investment channels can make the sleeping wealth wake up.

Capital is profit-seeking. As long as there is a good way to increase the sleeping wealth of the rich and powerful, there is no need to advocate or coerce, and capital will naturally pour into the circulation market.

………………

Li Dingguo was in Yunnan, on the one hand, to stabilize the situation for the prince of Qianguo, and on the other hand, he vigorously recruited and trained troops to accumulate strength, and at the same time launched commercial operations in Yunnan.

The reason why Zhu Shunming began to make coins was that in addition to the market demand, Li Dingguo also transported a large number of copper ingots from Yunnan to an important reason.

Yunnan produces copper, and copper ore is widely distributed. During the Qing Dynasty, Yunnan copper once accounted for more than ninety percent of the country's copper output, which shows the prosperity of copper mining in Yunnan.

Sha Dingzhou was not only driven out of Kunming and driven back to his hometown in Mengzi, but the wealth he had accumulated for generations and the wealth he had plundered from Kunming and other places were all swept away by Zhu Shunming.

Sha Dingzhou faced the desolate Mengzi, and wanted to cry without tears.

Soon, Zhu Shunming gave him hope of survival.

Mongolia produces its own copper, and the output is not small. Li Dingguo bought copper ore from Sha Dingzhou on a large scale, and then trained it into copper ingots to pay Sha Dingzhou silver or various materials he urgently needed.
