Chapter 939: Trial casting of brass coins

Do n’t underestimate the role of loose change in trade circulation, because that is the foundation of invigorating the market. For now, the Finney silver coins in circulation in the German region are actually equivalent to 50 yuan of large banknotes, which is very unfavorable for the circulation of small commodities.

In the current German region, silver coins are generally used only for transactions with a certain amount. As for ordinary small commodity transactions, they often do not use coins and can only trade things for things. However, in the case of barter, the value cannot be determined, which often results in irregular transactions. At the same time, the circulation of goods has been greatly affected.

Therefore, in the current German region, the circulation of small commodities is not smooth. If there is enough change, the circulation of high-end goods on the market will be more prosperous.

And the introduction of Malawi's small copper coins in Spain has been well adapted to the needs of the market. Therefore, for now, Spain ’s market economy is much more prosperous than the German region.

Another example is France, not to mention the low silver content of French silver coins, which are almost approaching copper coins. However, it is precisely because of the low silver content in French silver coins that the value of the currency itself is low. But this has promoted trade prosperity. Because, low-value silver coins are more able to adapt to small payments, which makes the economy more prosperous.

As for the Daming Empire, it goes without saying. In the Ming Dynasty, a thousand copper coins were worth a silver or two. It can be said that the copper coins of the Ming Dynasty were "zero" enough, which also stimulated the circulation of commodities. Generally speaking, in the Ming Dynasty, many children could also have a few coins in their hands to buy snacks.

But in Germany, because there is no change, most people only have a small number of small Finney coins. In many cases, because of the lack of change, it is necessary to adopt a very primitive trading method of "exchanging things for things". And this has greatly hindered the circulation of commodities and the development of social economy.

...

Therefore, coins with smaller denominations are necessary. However, according to the current silver-copper price ratio, a silver coin with 50% silver content is only equivalent to 8 copper coins of equal weight. If a silver coin contains only 25% of silver, it is only equivalent to 4.5 copper coins. According to the algorithm of a Finney silver coin equal to 50 yuan of later generations, a small copper coin of equal weight is equivalent to 6.25 yuan of later generations ...

"No!" Marin shouted suddenly.

He suddenly discovered that perhaps a copper coin worth 6.25 yuan could indeed not replace the small amount of money like 1 cent, 5 cents, and 1 yuan later on. However, it is very close to 5 yuan. At least, he has a much smaller denomination than the 50-dollar Finney silver coin.

In other words, using copper coins is more convenient than not using them. After all, 8 copper coins are equivalent to 1 Finney silver coin. At that time, instead of receiving 2 fenny silver coins, the workers received 16 copper coins every day. In this way, they are also more convenient to spend money.

As for the depreciation of copper prices in the future ... whatever he does, he will not lose anyway ...

Marin finally decided to harden his heart and promote the use of copper coins in the private sector ...

But at the same time, he will also use silver coins to exchange silver and gold from the people. That is to say, the copper coins are only put into the private sector for the commercial flow of the common people. The national reserves are still gold and silver.

In this way, even if the copper price falls in the future, the official loss will not be large ...

Although this is a bit lacking in morality, it is not unsolved. Because Marlin, who is about to send troops to Japan, will control Japan's cheap copper export channels. At that time, if the copper price fell, it would be a big deal to officially exchange some new copper coins for the public. After all, copper coins are also chronological. Just exchange the old copper coins in the hands of ordinary people for more new ones. So, the loss of ordinary people is not big.

But well, those copper coins exchanged to other countries will not be refunded. As for the gold and silver exchanged for those copper coins, it is naturally black ...

what? Are you in trouble with me? The truth? At the beginning I used copper coins for your gold and silver coins, but they came at market prices. As for the copper price plunge, is it my fault? As for me to exchange more new copper coins for the people of Beihai? They are my people, do you have an opinion? You can also bring your country to join the North Sea country, so many benefits ...

Not convinced yet? Come hit me! Just waiting for you to shoot first. That way, it just happened to swallow you up ...

...

In addition, Marin intends to use brass coins. Brass is a golden yellow copper alloy, which looks very good, a bit like gold. The coins made of brass are also golden, very similar to gold coins. For those businessmen who love gold coins, brass coins can definitely blind their dogs.

The reason for using brass, in fact, Marin also means to consume the zinc ingot in his hand. After all, after getting nickel, Marin does not need to wrap the bottom of the ship with tinplate. In this way, the sole role of zinc is to pretend to be tin and make tinplate.

However, the range of use of tinplate is not wide, and Marin is unwilling to promote the application of zinc for confidentiality. Therefore, the zinc in Marin's hands is actually backlogged.

The Bakens lead-zinc mine on Newfoundland still produces lead and zinc. Then, those zinc liquids cannot be wasted. And making brass for coining is a good choice.

Moreover, the cost of mining and smelting zinc is not high. Mixing zinc and copper not only improves the selling of copper coins, but also saves copper and reduces the cost of minting coins.

If it were not for Europe that there was an unwritten tacit agreement that gold coins were not adulterated, and it would be felt if the coins were bitten, it would be fine to forge inferior gold coins with brass.

However, in this era, whether it is Ducat or Gulden and other gold coins, the gold content is very high, and you can feel the softness with a bite. Therefore, casting fake gold coins with brass can only be considered. Another thing is that the density of gold is too high. Even if lead is added to brass, it is useless. Because the density of lead itself is not as high as gold ...

...

After making up his mind, Marin came to the metallurgical plant and asked them to smelt brass. But what depresses Marin is that mixing zinc and copper is not a simple matter. Because the melting point of copper is as high as 1083 degrees. But his meow zinc evaporated at 907 degrees ...

Although it can be collected by the top condenser tube, it is really difficult to melt and mix pure zinc ingot and copper!

In desperation, Marin can only use another method-first oxidize zinc, and then reduce it with copper ore, and finally get brass ~ www.wuxiaspot.com ~ But the problem is that after smelting brass, I can't use copper directly, I have to find enough refined copper ore ...

As for zinc, zinc ore cannot be used directly. Because there is also lead in zinc ore. Therefore, zinc ingots must be used for oxidation and then reduction. But the oxidation of zinc is not easy. Marin thought for a long time, let people grind the zinc into powder, then add water to heat, and continue to stir before it is oxidized, which is very troublesome to handle.

But fortunately, Marin finally got Jin Cancan's brass. Then, he took brass to the mint and let the mint masters use the craftsmanship and molds for making Finney silver coins to suppress a batch of small 1.5-gram copper coins of the size and appearance of Finney silver coins.

Then, with these golden brass coins, he found Jeffrey and discussed the possibility of promoting copper coins in Beihai ...

But unexpectedly, the first sentence of Jeffrey was:

"Duke, do you still have a mint?"

Malin suddenly-Nima, forgot to tell the prime minister the truth because of the counterfeit coins ...

But he can't tell Jeffrey that he is casting fake silver coins on a large scale, so he can only say vaguely that he has recruited several craftsmen who can make coins and let them try a few copper coins ... …

Jeffrey looked at the copper coin with the appearance of the Finney silver coin for a long time, and said:

"Then give it a try, anyway, copper itself is a high-priced metal, used to make money, no problem. Moreover, it is said that Spain and other southern European countries have already used copper coins. We first issue a batch of copper coins, put them into the private sector, try everyone Response. In addition, you need to send someone to design a copper coin appearance, which cannot always be the same as the Finney silver coin ... "

Marin nodded and agreed with Jeffrey's words. Then he arranged for the mint craftsmen to design the appearance of the new copper coins ...
