When the shipyard secretly set off a wave of steamships, Chu Yun was busy preparing for currency reform. The one who replaced the ship-type silver ingots was silver dollars. The production of qualified silver dollars was the prerequisite for currency reform. If even qualified new metal currencies could not be produced, it would be impossible to recycle silver taels of different shapes in various places.

Chu Yun brought Da Yu'er and some other officials in charge of currency reform to the same factory.

This factory is different from ordinary factories, with stricter inspections and guarded by soldiers carrying muskets. Even if Chu Yun and the others enter, they need to register normally.

"It turned out to be the military leader and several adults from the Ministry of Revenue! I will inform the factory director immediately!" The person in charge of the registration was very surprised when he learned the identity of the visitor.

"The Mint is the industry of Kyushu Bank, and the right to mint is owned by Kyushu Bank. Kyushu Bank needs to obey the decision of the Ministry of Revenue to issue additional funds and recover currency, and carry out production activities according to the decision." Chu Yun introduced the new factory to Da Yuer while waiting for the factory director to come out.

"After a while, a German engineer brought people out and was very happy: "Mr. Jun. Master, you have come. The silver dollar sample you ordered to produce has been successfully cast. Please let your subordinates lead the way!"

German engineers who served as factory director led Chu Yun and the others into the mint. Because it involves the minting of silver coins, copper coins and even gold coins, a batch of gold and silver was parked here, and the value of the "products" was also particularly high, so the management was strictly carried out.

"This is the elbow-moving pressing bed we produce, which is simpler than a spiral pressing bed, and the vibration and noise are not as large as that of a spiral pressing bed." German engineers introduced a strange machine to Chu Yun and others.

Da Yu'er saw a large flywheel and the body. The flywheel was connected to the body of the mint machine through toggles and bars, and used a steam-powered machine. The first time she saw a machine that casts silver coins, she secretly surprised her.

"We examined the coin minting method in the East. Most of them use the casting method, that is, the metal is heated and melted into a fluid, and poured into a mold to make money. This method originated from China, Japan, Goryeo, Annan and other countries that imitated China's use of this method. If it were put in the past, it was undoubtedly a relatively advanced and practical technology. It was more efficient than the Western purely hand-made hot pounding and can produce more currencies. However, after using spiral pressing and roller rollers from Italy in the late Renaissance, it would be more appropriate to make coins at room temperature through machines, so we gave up this high-temperature operation method."

"This elbow-moving press is more advanced than a spiral press and a roller roller. It can be punched 90 times per minute to produce coins with teeth, light edges and font edges. Master, you see, the toggle part is the most important part of the elbow-moving press. The use of the best-quality steel in the steel mill will make the elbow-moving press very durable, and it will be absolutely no problem if it has been used for decades. Steam power can allow this machine to produce a continuous stream of silver coins without complaints." The German engineer proudly introduced his works.

Chu Yun touched the toggles and continuous bars, and the precise mechanical texture came, which made him a little admire the rigor of the German engineers. In the 19th century, Germany was able to rise to become an important power in the Second Industrial Revolution under the siege of Britain, France and Australia, which was not unrelated to this group of people.

"Where is the sample of the silver dollar?" Chu Yun wanted to see if this coining machine could produce the silver coins he wanted.

"Mr. Junzhu, this is the first batch of silver dollars we produced according to the requirements. There are 120 silver coins in total, divided into 4 specifications, 26.6 grams, 13.3 grams, 5.3 grams, 2.6 grams, with a silver content of 90.5%, and the rest is copper. In actual manufacturing, the weight of different silver coins has some deviations in the silver content, but the overall conforms to the Gaussian distribution and the error is within an acceptable range." The German engineer continued to introduce and also used statistical methods.

The apprentice next to him brought a cardboard silver coin, which was divided into four grids, and placed four stacks of silver coins, both large and small, namely ten circles, five circles, two circles, and one circle.

Chu Yun took out a silver dollar with a weight of about 26 grams, and the unique texture of silver came from his fingertips.

This silver dollar is the largest ten-yuan silver dollar. On the front is the silver dollar denomination and coin time, and on the back is the dragon pattern with fangs and claws.

Domineering silver dollars! Chu Yun saw the dragon pattern behind him, in addition to being iconic, it also has artistic value. After using standardized machines, the silver dollars produced were very regular, which was even more exquisite than the Spanish silver dollars circulating in the international market.

The Spanish mined silver mines in the Americas and obtained a large amount of silver and cast it into Spanish silver dollars. They circulated in various places. At the end of the Ming Dynasty and before the Opium War, because China's foreign trade exceeded that, a large amount of Spanish silver dollars flowed in, and their quality was good and loved by the people of the southeast coast. Later, after the Opium War, a large amount of Spanish silver dollars flowed out, which became rare.

Chu Yun's purpose is to produce a batch of new silver coins to replace the status of Spanish silver dollars in international trade.

"The silver content is almost the same as that of Spanish silver dollars. It is more precise than that of Spanish silver dollars. It will accompany our goods to circulate all over the world." Chu Yun has high hopes for this new silver dollar.

"According to the current manufacturing process, as long as the raw materials are sufficient, the first batch of silver dollars can be produced day and night," said the Deutsche engineer.

"One machine is not enough. Our country's size is too large. The amount of silver in the people is unimaginable." Chu Yun said.

"Then we will produce four other coin machines? Five coin machines will produce the first batch of silver dollars and put them into the market to see how the people react. If the response is good, we will make a new coin machine." Wu Heng said.

"There is no problem. If the quality of the first batch of silver dollars can be guaranteed to be so good, it can satisfy ordinary people. After all, Spanish silver dollars have helped us verify the feasibility of this silver coins." Chu Yun said.

He didn't know that this batch of silver dollars with the dragon pattern printed on it would be called "dragon coins" by international merchants, replacing Spanish silver dollars as the standard currency for future international trade.

"Look at how about this silver dollar?" Chu Yun handed the silver dollar to Da Yuer.

With a crisp sound, Da Yu'er accidentally touched Chu Yun's finger when she took the silver coin, and the silver coin landed on the ground.

Even though Da Yu'er's calm person came to her senses, she changed her color slightly. She didn't take the things Chu Yun gave her.
