"Print on both sides, print on the central bank on the front, print on the reverse, print on the money one-word." Chen Xun replied.

Instead of naming this coin in history, the issuing bank is marked on the front and the currency value is marked on the reverse.

"Okay." Feng Yutie responded first, and then asked: "What is this central bank?"

"It is the department that manages all money shops and silver shops within the military government. It does not accept ordinary savings, loans and other businesses. It is only responsible for minting coins, printing money, issuing currencies, stabilizing financial markets, etc., and only deals with money shops."

"Oh..., I probably understand." I don't know if I really understood it, Feng Yutie did not continue to ask, but took out other coins for Chen Xun to review. These coins were forged according to Chen Xun's letter.

"This is an iron coin. Compared with ordinary iron tools, its rust resistance is stronger, but it is far worse than copper coin." There are three types of iron coin placed on the table.

"The smallest one weighs only one-third of the copper coin, and the middle one is one-half of the copper coin. This one is as heavy as a copper coin." Feng Yutie introduced: "It is said to be iron coin. In fact, their materials are all alloy steel, which is much harder than iron. As long as it does not rust, it is still very durable."

The heaviest iron coin looks bigger than a copper coin.

"Very good. These iron coins are all transitions and are consumables. It doesn't matter if they are rusted. Each bank will recycle old money." Chen Xun did not take a closer look at these iron coins. They are real auxiliary coins, just to provide the people with daily sporadic transactions and change-making purposes.

Later generations of RMB have all jiao and are divided into auxiliary coins. The value of a penny of copper coins is not much different from that of one yuan, and there must be a auxiliary coins with a smaller denomination.

At present, folk people will use metals such as copper as auxiliary coins, and Chen Xun intends to directly unify these small denomination coins.

"How much does it cost?" Chen Xun asked.

"It's more profitable than building other iron tools." Feng Yu Tiehui said: "Especially after the steam engine was developed, it was directly used to use casting machines to forge it. It has good quality, fast speed, and very low cost, which is less than 10% of the currency value."

This is the huge profit of coin minting!!

When it comes to making money, it is still the most profitable to print these small denominations, and the high denominations are not bad either.

"This is the silver and gold coins you gave."

The silver coins and gold coins on the table are very different from the iron coins and copper coins before. There are no holes in the middle and there are jagged patterns on the outer edges of the coins to prevent anyone from scratching silver or gold coins from the coins. The patterns on the front and back sides are very complicated, and they are a flower.

"The weight of silver coins is five cents and contains only 80% silver. This alloy is much harder than sterling silver, and the pattern can be made very rich. When you look at the flower, the patterns are already very thin." Feng Yutie introduced.

Five cents are equivalent to 32 grams of later generations.

"It's very good, just make it according to this size." Chen Xun picked up the silver coin and checked it carefully. The size and weight exceeded that of the silver coin in later generations, which was very kind.

"I'm more curious. Can this silver coin be used as a tael of silver?" Feng Yutie couldn't help asking, "That's too profitable."

"Of course, otherwise why should we pay for this? Wouldn't it be better to just use sterling silver?" Chen Xun clamped the silver coin with his nails, put it beside his mouth and blew it, then put it close to his ears and listened, and the silver coin made a crisp "ding" vibration.

Chen Xun later read a popular science article, saying that he could tell the truth about the authenticity of the coins by playing money and listening to the sound, not to see whether there is a sound, but to hear the sound.

As long as the standard kneading method and appropriate blowing method are used, most metal coins can make sound.

However, the sound of real silver dollars will be crisper. Experienced people can distinguish whether it is real silver dollars by the sound quality of the sound.

The principle should be related to the "resonance" phenomenon in physics, and Chen Xun also doesn't understand it in detail.

"What is printed on the silver coins?" Feng Yutie asked.

"I have already drawn it, just print it accordingly." Chen Xun took out a drawing with four circles printed on it, which he designed for silver and gold coins.

The center of the front of the silver coin is a five-clawed dragon, which is plated into a ball, with the dragon head located in the middle, with the central bank written above the pattern, and the Qian Qianwen written below, and the wheat ears are filled with patterns on both sides.

Chen Xun's big portrait was printed on the back, with eight words written on it: "The 3824th year of Kaiyuan Lunar New Year"

The Kaiyuan here is not the reign of Emperor Xuanzong of Tang Dynasty, Li Longji, but the beginning, the meaning of the beginning, and the meaning of a new stage and a new era.

The lunar calendar, also known as the Xia calendar, Han calendar, lunar calendar, etc., is the most widely used calendar in China today. It is a calendar founded in the Xia Dynasty and can be regarded as the earliest calendar in Chinese civilization.

Chen Xun chose this calendar to trace the origin and inherit the connotation of Chinese orthodoxism, and he would also promote it in this way later.

Fortunately, Chen Xun studied the lunar calendar in his previous life and knew that the Xia calendar era was 2697 AD. Otherwise, with the current archaeological level, it would be absolutely impossible to trace the correct year.

"Kaiyuan lunar calendar? March 824?" Feng Yutie was confused.

"The time must be printed on it. Now that the Song Dynasty is destroyed, we cannot continue to use the year name of the Song Dynasty, so I chose this calendar. Kaiyuan means the beginning, the lunar calendar is the Xia calendar, and the Xia calendar originated from the Xia Dynasty, which is the lunar calendar, the stem and branch calendar and the twelve zodiac calendar. Our Chinese nation is based on agriculture, so I call it the lunar calendar." Chen Xun replied: "This calendar has been 3,824 years since then."

"Ah!!?This..., how did you know?" Feng Yutie asked curiously.

"You can just use it directly, you won't be wrong." Of course, Chen Xun couldn't tell the reason, so he could only act like a rogue.

In fact, although the lunar calendar is called agriculture, it cannot reflect the seasonal change to accurately guide farming.

Because it is obtained by observing the moon, its biggest function is to reflect tides. The tide phenomenon is the moon playing a dominant role. The lunar calendar based on the phase changes of the moon can guide maritime activities, which is very suitable for the current military government.

After the founding of the country, Chen Xun also planned to study the solar calendar.

More than a hundred years later, the Yuan Dynasty observed the sun and studied the "time calendar", and Chen Xun believed that he could measure it.

Thinking of this, a small story popped up in Chen Xun's mind.

Three hundred years after the emergence of the scheduling calendar, the Pope introduced the Gregorian calendar (Gregorian calendar), claiming to have formulated it himself, but his 365-2425th day of the year was not a point from the scheduling calendar. He neither had the vast land and manpower of the Yuan Dynasty to measure it, nor had historical measurement records.

Most importantly, before the emergence of the Gregorian calendar, Zheng He sent a team to Florence, Italy. Deputy Envoy Zheng He met with Pope Eugene IV and spread a large amount of Chinese astronomical calendar and cultural knowledge to Europe, including the Ming Dynasty's "Evaluation List" and the Yuan Dynasty's "Time Calendar".
