Chapter 17 Silver Coins Without Silver
Marin had long been unhappy with the Oldenburg Kingdom in the east. Relying on the support of the Nordic Viking King Denmark, he simply did not take East Friesland seriously. Denmark was also abominable. It supported the Oldenburg Kingdom, which led to Marin's inability to control the hundreds of square kilometers of land in the Yevre area now.
Therefore, when Marin was training in Teutonic, he specially asked Old Sten Sturre to send a group of Swedish officers to practice together. At present, these people have learned their skills and have returned to Sweden to start. Marin also intends to support their independent actions economically.
For this reason, the mint that had been specially used to mint bad coins, which had been on hold for a long time, started construction again...
This time, Marin targets the Danish economy - he plans to mint millions of bad money from Danish currency...
Oh no, it should be said that Marin did more unethical this time - he directly planned to mint a batch of counterfeit currency in Danish currency...
Previously, the bad coins of the silver coins issued by the Principality of Saxony minted by Marin were just mixed with more lead and less silver. In short, it was still silver coins.
But this time, Marin came up with a good idea and was about to play a big one - he planned to directly mint a fake Danish silver coins without silver...
How to avoid silver? It is not possible to use copper and lead alone. If copper and lead alone, it becomes bronze, which is completely different from silver coins. Speaking of bronze, Marin remembered another kind of bronze - copper-tin alloy...
Thinking of tin, Marin contacted the alloy of copper and lead that he had thought of before, and thought of the alloy of lead and tin - solder...
In his previous life, when Marin was in school, he worked in an electronics factory during the summer vacation and used soldering circuit boards. Of course, he knew about soldering.
The so-called solder is an alloy of lead and tin. Among them, the lead content accounts for 37 and the tin content accounts for 63%. The solder looks silver-white on the outside, very beautiful, and looks very similar to silver, and is very soft.
At the same time, because of its high lead content and high density, it can be used to impersonate silver. However, solder is almost the same as using sterling silver, and can be used to impersonate silver coins... Forget it...
Because there are currently no high-purity silver coins in Europe, they are basically silver-copper alloys, and even the copper content of most silver coins accounts for half or more.
For example, the silver content of French silver coins is almost lower than 25%. No matter how low it is, the color of the silver coins will no longer be silver-white, but will turn yellow.
It is precisely because of the high copper content that the current silver coins are very hard, which is completely different from sterling silver. In fact, later, the Spanish made silver dollars and deliberately mixed them with 10% copper to keep the silver dollars in a certain hardness and strength, so as to prevent the silver dollars from deforming easily under external forces because they are too soft.
Therefore, it is not appropriate to use lead-tin alloy solder to pretend to be silver minted coins. Because it is too soft...
However, appropriately increasing a small amount of copper can increase hardness...
So, Marin imported a large amount of lead from Southern Europe, and imported a large amount of tin from Cornwall, England, and then started the "falsification" plan with the reserved copper bought from India...
After calculation, Marin incorporated 10% copper into the "silver coins" to increase the hardness of the "silver coins". Then, the proportion of lead and tin is adjusted to achieve the same density as the imitated silver coins. In this way, coins of the same size are as heavy as real coins, with the same appearance and the appearance are equally silver-white and bright, and the hardness is not bad, which is difficult for outsiders to see. Unless... someone burns this "fake coins" with a fire...
Because the melting point of solder is very low, only 183 degrees. Even if copper is added, the melting point will not exceed 200 degrees. If the pan of cooking is heated on high heat, it can reach this temperature. As long as someone puts the coins in the stove and heats them to more than 200 degrees, he will be surprised to find that the "silver coins" have melted...
However, there are not many boring people in the world who throw silver coins into the fire to heat them...
Moreover, Marin is trying to cheat Denmark this time. Who is asking Denmark to support Oldenburg's country in interfering in the internal affairs of East Friesland?
Marin soon found a sculptor, carved the relevant molds, and began to imitate the Danish Finney silver coins engraved with the surrender of the Danish King Hans...
Denmark is close to Germany, and many habits are similar to Germany, and even the most basic currency is Mark and Finney. However, in the northern region of the Kalmar League controlled by Denmark (Sweden and Norway), the basic currency is not Finney, but a small silver coin with a value of Finney - Otug (?rtug).
However, Denmark is a big country, and Congsberg, southeast of Oslo, Norway, is a famous silver mine. Therefore, the Danish currency contains good silver content, reaching about 50%. Whether it is the Finney silver coins circulated in Denmark, the Principal of Schleswig and the Principal of Holstein, or the Ottog silver coins circulated in Norway and Sweden, the silver content is about 50%, which is very strong in the European market.
At present, the silver coins circulating in the Kalmar League are mainly Finney and Otug with the portrait of Christian I. However, since Christian I passed away in 1481, Denmark has stopped minting such silver coins. Since 1481, Denmark has begun to mint silver coins engraved with the portrait of the current King Hans, and the circulation is temporarily unable to keep up with the silver coins with the portrait of Christian I.
However, whether it is the silver coins in the portrait of Christian I or the silver coins in the portraits of "Margaret I", "Eric VII" or "Christopher III" are engraved earlier, because they are minted for a long time.
Marin pressed it with a spiral coin machine, which must be brand new coins. Therefore, Marin could only choose to forge a new "silver coins" engraved with King Hans's avatar. After all, King Hans has been ascended the throne for nearly 20 years, and there are not many silver coins that are officially minted with his avatar.
However, in order to avoid accidentally hurting the ally Sweden's economy (Sweden uses Otug with the portrait of Christian I and King Hans), Marin decided to only imitate the Danish Finney silver coins circulated in Denmark and the Principality of Schleswig and the Principality of Holstein...
Of course, Marin's "silver coins" only contain lead, tin and copper, and does not contain silver at all, and it is full of counterfeit coins...
However, from the outside, it really can't be seen. Even from the hardness, it's harder to see. Because some copper is added to the currency...
Marin was surprised when mixing. The melting points of lead and tin are more than 300 degrees and more than 200 degrees respectively, but their boiling points are both more than 1,000 degrees or even more than 2,000 degrees. Therefore, copper and them can be fused smoothly. If they were replaced with zinc, although the melting point was higher than that of lead and tin, reaching more than 400 degrees, the boiling point of zinc is lower, and it will turn into zinc steam and evaporate after reaching more than 900 degrees, and it is difficult to fuse with copper. Of course, it is very simple to fuse with lead and tin.
After several attempts, Marin's mint successfully developed a "silver coins" without silver. Then, Marin directly issued a production task - minting 2 million Danish Finneys to impact the Danish market...
The cost of the machine coins produced by the Marin Mint is very low because they do not contain high silver. Even the prices of lead and tin are lower than that of copper at this time. Therefore, the cost of this counterfeit currency is lower than that of silver-copper alloy counterfeit coins. Producing 2 million coins will make Marin profitable...
