Chapter 843： Which is strong in minting technology

It turned out that Marin did not expect that when the fake "French silver coin" was made, it was much stronger than the genuine French silver coin. After trial casting a thousand small French Dnier silver coins, Marin compared them for half a day, and found that the specifications of these thousand “French silver coins” were very consistent and perfect to perfection.

But in fact, the real French silver coins are all hammered out by craftsmen with hammers and simple stamping dies, and the quality is far from comparable to machine-made coins.

Such high-quality silver coins cannot be made by French officials. If the shipment volume of Nimade is small, for example, tens of thousands of tens of thousands, it is better to say that if it is a few tens of millions, it will definitely alarm the French official. After all, who else have you seen hundreds of thousands of silver coins exactly the same? It's too good to be flawed ...

It was like a Japanese team posing as Eight Route during the Anti-Japanese War and wanted to cut off the Eighth Route Command. As a result, the devil of this team speaks Chinese very well and speaks dialects ... but it ’s because everyone in this team is wearing The new clothes, the equipment is completely new, and the horses that are riding are all Oriental horses ... and then it was exposed ... After all, the real eight-way is very poor, and it is normal for the soldiers to patch their clothes. The equipment and equipment are brand new, and others do n’t believe it ... Also, the horses on the Eighth Route Army were mainly local horses, and there were few Oriental horses seized.

Marin can't wait to fan the artisans responsible for counterfeiting French silver coins. Are you a tiger? Is it so well built that others can't see it? Moreover, in this era, there is no such unified silver coin. After all, it was hand-made, and the error was huge.

Also, the density of fake silver coins is not well controlled. Because the density of nickel and copper are 8.9 grams per cubic centimeter. When the two are mixed, the density is naturally 8.9 grams per cubic centimeter. However, the alloys of silver and copper are different. The density of silver is 10.53 grams per cubic centimeter, which is obviously higher than copper and nickel. If you want to make fake silver coins that are hard to distinguish between true and false, not only do you have to look like it, but you also have to be about the same size and density. After all, in this era, there is a very simple way to distinguish the authenticity of silver coins-the comparison method ...

An experienced person only needs to compare the two silver coins and then weigh them with a simple balance. As long as a real silver coin is used as a reference, another silver coin can be seen by weighing and comparing.

But it is precisely because this method is simple and backward that Marin is given room to operate-as long as the density and appearance are similar, it is difficult for people of this era to see.

In fact, Marin had made a counterfeit currency of lead, zinc and copper before. But the problem of counterfeit currency is very big, why? Because the density of zinc is only 7.14 grams per cubic centimeter. If you want to create a realistic fake silver coin, you must add more lead to fill the density difference.

The problem is that if more lead is added and the time is long, the appearance of the "silver coin" will become black. After getting black, you can use this fake silver coin as a pencil ...

The density of nickel is the same as copper, so that when making fake silver coins, you can add less lead. As long as there is less lead, the problem is not big. As long as the lead is added so that the density is similar to that of real coins, and because the density of copper and nickel is the same, nickel can be placed as much as you want.

Moreover, the processing and smelting of Cuban laterite nickel ore is very simple. Although the laterite nickel ore is accompanied by cobalt ore, the nickel block obtained by the reduction reaction is fine even if it contains cobalt metal. Because the density of cobalt is also 8.9 grams per cubic centimeter ...

The mining and smelting of copper mines is much more complicated, because the copper content of copper mines can reach 1% even if it is rich ore. Like the Fa Yilun copper mine, it can have several percent of copper content, even if it is rich.

In addition, more than half of copper mines are associated mines, often accompanied by various associated mines such as gold, silver and iron. Therefore, the screening of copper mines is very troublesome. The composition of laterite nickel ore is relatively simple. The metal is mainly nickel with a small amount of cobalt, which is easier to handle.

In terms of mining and smelting costs, nickel production costs are much lower than copper. Therefore, Malin would rather add more nickel. However, considering that he would engage in stainless steel in the future, he still saved a little bit. But the first batch of fake silver coins, Marin still added a lot of nickel. The reason is that-European copper prices are too expensive ... use too much copper, the cost is a bit high ...

But in the future, if cheap copper can be obtained from the Ming Dynasty and Japan, he would prefer to add more copper. After all, nickel as a whole is a rarer strategic metal resource than copper.

That is, Marin is a traversal, and it happens that Cuba has easy-to-find laterite nickel ore, so that the cost of obtaining nickel is relatively low. In addition, this time Marin mainly lacked currency, so he would use a large amount of nickel to make counterfeit currency. If he can get a lot of cheap copper and silver, he is not happy to use nickel metal to make counterfeit coins.

...

This time, Wiltz did a great job in Cuba. After all, he was born as a mine engineer and was too experienced in mining. This time, Marin obtained 50 tons of nickel metal, which is equivalent to 50 million grams. If you add 1 gram of nickel to each 1.5-gram fake silver coin, you can make 50 million French Dnier silver coins!

What is the concept of 50 million Dnier? The conversion ratio of Denier to Imperial Finney is 2 to 1. That is to say, 50 million Denier is equivalent to 25 million Finney. And 60 Finney is equal to one Ducat gold coin, so 50 million Dnier is equivalent to 416,700 gold coins ...

Although there are costs to coining coins, Marin can guarantee that he will replace nickel with nickel metal and use a screw-type coin press to make coins with greater profits than ordinary countries.

...

The only problem now is that the fake "French silver coins" faked by the Beihai Mint are of good quality. In order to solve this problem, Marin finally thought of a way-increasing error method ...

What is the "increasing error method"? It is to make the mold for casting money rough. Then, a gap was intentionally made between the mold and the base of the screw press. Once there is a gap, when the screw-type coin press presses the fake silver coins, the mold will slide, causing a pressing error, which makes the pressed silver coins a little skewed.

Also, the mold is carved as rough as possible to make it look like it was made manually. In addition, Marin also ordered carving hundreds of different rough steel money molds to suppress fake French Dnier silver coins.

After many adjustments, under the command of Marin, the craftsmen finally mastered the trick, making the mechanical coins look rougher and closer to the hand-made silver coins.

I believe that after this batch of fake French silver coins worth 416,700 gold coins is successfully built, Marin will definitely make more than half of the profits. But this is still secondary, because only with enough coins can the market become more active.

Of course, this batch of counterfeit currency was placed on the French market, not the domestic market. What Marin has to do is to compete with French officials for the mint tax and crack down on French finances.

In order to disrupt the French market, Marin has asked the Beihai Chamber of Commerce in Paris to secretly contact a large number of French financial merchants. Then, through their hands, the fake silver coins were exchanged for gold. Then, take it back to the German area, exchange it into real silver coins, and bring it back to the North Sea country for circulation.

In addition, these fake French silver coins cannot be distinguished by people of this era. Therefore, Marin can use it to buy valuable goods in France.

For example, French wine is very popular in Europe and can be bought as a hard currency. In addition, the French warhorse can also be bought with fake silver coins.

Also, the famous Charlotte cow in France ...

Charolais cattle are a famous large beef cattle even in later generations. The advantages of Charolais cattle are fast growth and large size. In later generations, this may be nothing, but in this era, it is an extremely important advantage.

Why? Because cattle are not only used to eat meat in this era ~ www.novelhall.com ~ but also use cattle to cultivate land. Obviously, large cattle are more powerful than small cattle and are more suitable for arable land.

Like the Angus cattle of the British line, although they grow fast, they are not very big. The weight of an adult bull is only 500 to 700 kg.

Charlotte cattle can grow to 500 kilograms in 12 months. Adult Charolais bulls, weighing between 1100 and 1200 kg, are almost double the size of Angus ...

Of course, this is data for future generations. In this era, Charolais cattle data may not be so good. But it can certainly be a great advantage as a female parent of a famous cattle breed in later generations.

By the way, the data of the Crimean export cattle is not very good, it is not comparable to the size of Charolais cattle, and it is more similar to the Angus cattle data. Therefore, Marin only remembered the French Charolais cattle.

Therefore, Marin intends to use the opportunity of casting fake French silver coins to exchange French gold and purchase French valuable goods. The Charolais cattle, as an excellent meat and service breed, is also one of Marin's important procurement goals. It is purchased with cast fake silver coins and pitted the Frenchman once ...
