The face value of this series of currencies is basically a reference to the value of precious metals in this time and space.

Weighing eighteen grams and having a gold purity of 97 percent, this is a harder and easier to stamp.

The Han Tang Group designated one gold coin as equal to five silver coins.

Silver coins also weigh eighteen grams and have a silver purity of ninety-seven percent, for the same reasons as gold.

The Han Tang Group designated one silver coin as equivalent to 500 copper coins of one yuan.

The copper coin weighed twelve grams, which was about the same as the weight of a minted copper coin of this era.

The face value of copper coins is different, they are one, five, ten, twenty, fifty, they are different in area and pattern, there are concave and convex marks on the surface, you can also know by touching it.

At this time, it is easy to appear that everyone likes to accumulate copper coins with small currency value, and does not like the phenomenon of large currency value copper coins, which is completely guaranteed by the Hantang Group, as long as the Hantang Group guarantees that the corresponding materials can be exchanged at any time, it is okay to flow quickly.

The Hantang Group fully estimated this, and at this time, it was necessary to add tinplate coins, especially those with a five-cent denomination.

Hantang Group designated a copper coin equivalent to one hundred tinplate coins, with a face value of one, two and five cents, this area is smaller, and one, two and five cents are larger.

The Han and Tang groups named the currency Han Tang Yuan, referred to as Yuan, and also specified the number of huàn with the horse ticket, which is still in circulation.

Within Taiwan, other currencies are henceforth not recognized and protected.

The people of Hantang Group don't even need mathematical knowledge, and they desperately try to make such a rigorous system, and they don't hesitate to carve a few more molds!

Of course, the Ming and the Ming merchants or other merchants could exchange silver with gold and copper, and after discounting the purity, they were subject to a seigniorage of three percent, which was equal inside and out.

Here, the currency has returned to its symbolic role, but considering the economic characteristics of this time and space, precious metal currency is still allowed to participate in circulation, and Hantang Group absolutely believes that it has the ability to absorb gold.

At the beginning, some technicians were worried and said: "In this time and space, because North and South America have just completed the evolution of silver extraction and refining level, silver production has risen, prices have continued to fall, and gold has been rising. ”

The powerful accountant laughed, thinking, this guy still doesn't understand the essence of money.

He replied leisurely: "Yes, we are 1 to 5 here and 1 to 15 in Europe, and there is a big difference on the surface, but they will never take our gold back, and they can only bring gold from Europe to us...... Because in the final analysis, money is still equal to goods...... You say that how many times the profit is for them to buy supplies from us with gold and bring them to Europe? ”

The technician immediately understood, this is not, if they buy the supplies here, even if they ship them to India, it may be fourteen times more profitable, and if they are shipped to Europe, it may be seventeen times more! How big of a head do they have to put on gold and go back and make three times the profit? Sit on the ground and pay for death.

Manager Merozie slowly played with various metal coins, thinking to himself, it won't be long before this thing will run rampant all over the world, and now there is no unified monetary system in all regions of the world...... As long as the liquidity is increased, the currency of our Hantang Group is likely to become a kind of basic number of conversion among the various forces, ah, then it will be the status of Ran! Of course, it depends on where our businessmen go.

I had the privilege of being a promoter and witness, and Manager Merges unconsciously made a silver coin roll back and forth on the back of his finger, mischievously and skillfully.

Wang Zuxian had just finished comforting the two little girls, they were crying indecently, and Lezhi had a set of techniques to scare the girls.

After Wang Zuxian came back, he saw those hard coins at a glance.

No matter what time and space, where can a woman resist something shiny.

She was ecstatic to learn to play with it, god, what a sight to behold.

"Xianggong, I want it."

"This is not good, it is now the property of the Hantang Group, and it will be placed in the museum in the future...... But soon, I'll get you back in a complete set, maybe another commemorative coin—"

A wise woman will know when to shut up, and a stupid woman will only ask why.

Wang Zuxian immediately stopped talking, and concentrated on playing hard and coin.

Holding up the gold coin, she asked, "Behind it is the flag emblem, what is in front of it?" Weird? ”

"It's called a hot air balloon, and the back and background behind it is the first satellite of mankind, and the fire-breathing is the Long March-2 rocket...... The future of mankind is in the sky, in the universe ......"

"Xianggong, do you think I can fly in the sky in the future? Like your guys? ”

"Zuxian, I can promise you this, I will definitely be able to ......"

She held up the silver coin again and asked, "What's in front of this?" Doesn't it look like a ship? I saw the word Chang'e. ”

"It's a ship, and its full name is Titanic...... Also known as Chang'e, it is a famous passenger ship in Antarctica...... Behind it is a ground-effect airplane and a hovercraft in the background. ”

Manager Mei Lezhi thought to himself, this director Li Ziqiang is really idle and has nothing to do.

"Yes! So why not bring it with you? ”

"Our chengguan there won't let ......"

Wang Zuxian looked at the gears on the copper coin again, the two bunches of rice on the iron coin, and did not ask any further, and after a long time, Director Li Ziqiang sincerely apologized to everyone on the Internet, and everyone spent a lot of meaningless saliva for his idle and boring patterns.

Captain Sun Yu is going to transfer manpower from Captain Hao Gang's 6'an Brigade, after all, his sailors still have a few months of military training, and it is easier to get started after getting on the ship.

This is just Captain Sun Yu's plan for the Haian Brigade.

Of course, Captain Hao Gang is a little dissatisfied, this is about to be recruited, and the veterans in his hands are all Zhenhai Shenpin-like storage zài, and the future military discipline and military training will play a big role, but I don't want to give the Haian Brigade, isn't this a bit of a peach picking?

Captain Sun Yu clenched his fists and kept shaking and said, "When I come back from India, I will bring you such a big gem, and if I am not allowed to do business, I will not be able to buy personal belongings." ”

Captain Hao Gang was almost angry: "Damn, when I'm a girl?" Now that thing is worthless, if it weren't for the overall situation, why would you smoke my people! ”

Captain Sun Yu said: "Old Hao, you are more profitable!" ”

"Ahh

"We're going to have to have Navy 6 in the future, right? In the plan, half of you and half of me, you can see it, this is divide and conquer—"

Captain Hao Gang was in a bad mood and said: "Nonsense, the Navy 6 Squad can only listen to the orders of the chairman and bypass the board of directors, although it can't be internal, but the strength is so big, I have to do two for it!" ”

"Yes, when the time comes, you will draw a few more people back, won't there be an old team?"

"Don't fool me, dozens aren't enough—"

"It's the ground, it's the ground, it's all easy to say, smoke a cigarette, and be heartless!"

After lighting the cigarette, Captain Sun Yu deftly dodged Captain Hao Gang's big hand and kept the lighter.

Captain Hao Gang said: "Okay, can you still escape my catch - the new lighter has come out?" ”

Captain Sun Yu handed it to him again, I can show it to you, but I can't grab it, he smiled and said, "Just came out, I went to pick it up myself, you see it's the size of a mobile phone." ”

Captain Hao Gang took it, pushed it with his thumb, opened the lid, and at a glance he knew that it was a white copper welded cover, and then he looked at the lighter, a radius of one centimeter, and as soon as he pressed the lighter, a two-centimeter-long spark beam burst out, and the cotton thread was hit at once.

Captain Hao Gang sniffed it and said, "Alcohol? ”

He shook the lighter again and said, "Can it be used for a few days, can it be used to make it so big?" ”

Captain Sun Yu naturally took back the lighter, shook it, and it was detained with a snap, and said: "It can be used for four or five days, not so big, one is that the lathe of the Ming people can't process it, the second is that our magnesium strip is not pure enough, I'm afraid that the spark is not enough, and the third is to also load more alcohol, not afraid of danger, the inside is soaked with a cotton belt, and there is no liquid flowing out." And one more thing, I almost forgot-"

He pushed open one of the lids at the bottom and pulled out a magnesium bar.

This is an accessory, but also a standard for survival in the wild, once there is no match, no alcohol, just use the lid of the lighter to scrape off some magnesium chips, and then use some hay to make a fire, then vigorously turn the lighter, very easy, a few times to ignite, of course, you can also sprinkle some gunpowder, so you don't need magnesium chips.

When Captain Sun Yu was leaving, he said: "You can still smash people, the machining gang is unwilling to do it, and the Ming lathe and welders are at this level, bear with it." ”

Captain Hao Gang rolled his eyes, he didn't know how to machine, but he went to get one after a while, and also sealed his original one, just when the oil was about to be used, and he didn't bring much at that time, the quota was precious, not to mention, the cottage Dupeng was also a high imitation.

In fact, everyone knows that this magnesium strip lighter is a by-product, which is the same as the exposure powder of Liu Yun's self-made old-fashioned camera, of course, alloy steel also needs some, these are not much, there are hundreds of kilograms, enough for them to play for half a year.

Hantang Group can't even afford stainless steel now, and has been using enamel to deal with it, not to mention aluminum-magnesium alloy.

Aluminum, is the product of the next stage, if this thing is put into production, in terms of electricity use, don't play anything, it's not cost-effective.

Otherwise, everyone is staring at hydropower construction this winter.

The opening of magnesium is relatively simple, the brine can no longer be used to assist in drying salt, and the by-products of the sodium hydroxide workshop and the potassium chlorate workshop, the high brine is thrown away in vain, and it hurts people.

The director of Andefu organized the new Daming chemical workers to react the high brine with lime water and slowly filter out the sediment.

The director of Andefu said: "You know, right? After filtering it out, it is dried and sent to me. ”

The new Daming chemical worker said: "One glance, one glance." ”

In another workshop, the director of Andefu said to the old Daming chemical workers who had worked for a year: "Strong acid reaction, everyone be prepared!" ”

Lao Daming's chemical workers are very obedient and honestly prepared.

The director of Andefu instructed the workers to put the precipitate into the low-pressure reactor, covered the lid, and checked it twice.

Magnesium hydroxide and hydrogen chloride are concentrated in the reaction, and the sound from various pipes is normal.

Fortunately, it was another safe day, and the director of Andefu thought that the electrolytic melting of magnesium chloride would be simple, and the temperature of only 700 degrees would be easy to do.

For the ocean-going training program, they have to get flares or flares out, which are needed for sea voyages, and it's a by-product of the more versatile use, that's another matter.
