Marin had long been unhappy with the Earl of Oldenburg in the east, relying on the support of Denmark, the Viking king of Viking, and he simply didn't take East Friesland seriously. Pen ~ fun ~ pavilion www.biquge.info and Denmark is also hateful, supporting the Earl of Oldenburg, so that Marin is now unable to control the hundreds of square kilometers of land in the Jävre region.

Therefore, when Marin was training in the Teutonic country, he specially asked the old Sten. Sturley sent a group of Swedish officers to practice together. Now, this group of people has learned their skills and has returned to Sweden to get ready to do it. Marin, on the other hand, intends to financially support their independent actions.

For this reason, the mint, which had been dormant for a long time and was used to mint bad coins, was reopened......

This time, Marin is targeting the Danish economy - he intends to mint millions of bad coins of Danish currency......

Oh no, it should be said that Marin was even more immoral this time - he directly intended to mint a batch of counterfeit Danish currency......

Previously, the silver coins issued by the Duchy of Saxony minted by Marin were only mixed with more lead and less silver. Counting it up, it's still silver coins.

But this time, Marin had a brilliant idea and was going to play big - he was going to mint a fake of a Danish silver coin without silver......

How to not contain silver? Copper and lead alone will not work. If it's copper and lead alone, it's bronze, not like silver at all. Speaking of bronze, Marin remembered another kind of bronze, copper-tin alloy......

When he thought of tin, he thought of the alloy of copper and lead that he had thought of before, and the alloy of lead and tin - solder......

In his previous life, Marin went to work in an electronics factory during the summer vacation when he was in school, and he also used solder to solder circuit boards. For solder, of course, he knows.

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 has a silvery-white appearance, which is very good-looking, and the appearance is very similar to silver, and it is very soft.

At the same time, because of its high lead content, its density is also very high, and it can be used to pass off silver. It's just that solder is used to pass off as sterling silver, and it can be used to pass off as silver coins...... Or forget it......

Because, at present, there are no high-purity silver coins in Europe, which are basically silver-copper alloys, and even most silver coins account for half or more of the copper content.

For example, the silver content of French silver coins is almost less than 25%. If it is lower, the color of the silver coin will no longer be silvery-white, but will turn yellow.

It is precisely because of the high copper content that silver coins are now very hard, and the properties are completely different from those of pure silver. In fact, later the Spaniards made silver dollars, but also deliberately doped with 10% copper, so that the silver dollars maintained a certain hardness and strength, so as to avoid the silver dollars being too soft and easy to deform under external forces.

Therefore, it is not appropriate to use the solder of lead-tin alloy to pass off as silver to mint silver coins. Because, too soft......

However, adding a small amount of copper can increase the hardness......

As a result, Marin imported a large amount of lead from southern Europe, and a large amount of tin from Cornwall, England, and then used the copper from India in reserve, and began a "counterfeiting" program......

After calculations, Marlin mixed 10% copper into the "silver coin" to increase the hardness of the "silver coin". The ratio of lead and tin is then adjusted to achieve the same density as the imitation silver coin. In this way, coins of the same size weigh as much as real money, have the same silver-white appearance, and are not bad in hardness, which is difficult for outsiders to see. Unless...... Someone burned this "counterfeit money" with a fire......

Because, the melting point of solder is very low, only 183 degrees. Even with the addition of copper, the melting point does not exceed 200 degrees. If the pot for stir-frying is over high heat, this temperature can be reached. Anyone who puts a coin in a furnace and heats it to more than 200 degrees will be amazed to find that the "silver coin" has melted down......

It's just that there aren't many such boring people in the world who throw silver coins into a fire to heat them up......

Moreover, Marin is trying to trap Denmark this time, who told Denmark to support the Earl of Oldenburg to interfere in the internal affairs of East Friesland......

Marin quickly found an engraver, carved the relevant molds, and began to imitate the Danish silver finney coin engraved with the surrender of the Danish king Hans......

Denmark is close to Germany, and many of its habits are similar to those of Germany, and even the most basic currencies are the mark and finney. However, in the northern part of the Kalma Confederation under Danish control (Sweden and Norway), the basic currency was not a finnig, but a small silver coin equivalent to a finnig, the oltug (?rtug).

However, Denmark is a big country, and Congersberg, southeast of Oslo, Norway, is famous for its large silver mines. Therefore, the Danish currency has a good silver content, reaching about 50%. Whether it is the silver finney coins in circulation in Denmark and the Duchy of Schleswig and Holstein, or the silver Otug coins in circulation in Norway and Sweden, the silver content is about 50%, and they are very strong in the European market.

At present, the silver coins in circulation in the Kalmar Union are mainly Finney and Otugu, which are engraved with the head of Christian I. However, since the death of Christian I in 1481, the silver coins were no longer minted in Denmark. Beginning in 1481, Denmark began to mint silver coins engraved with the head of the current king Hans, and for the time being, the circulation could not keep up with the silver coins of the head of Christian I.

However, both silver coins with the head of Christian I and earlier silver coins with the heads of "Margrethe I", "Eric VII" or "Christopher III" are very old because of their age.

What Marlin pressed with a spiral mint must have been brand new. Therefore, Marin had no choice but to forge a new "silver coin" engraved with the head of King Hans. After all, King Hans has been on the throne for nearly 20 years, and there are not a few official silver coins engraved with his head.

However, in order not to inadvertently hurt the economy of his ally Sweden (Sweden used Otug engraved with the portraits of Christian I and King Hans), Marin decided to copy only the Danish silver finni coins that circulated in Denmark and in the Duchy of Schleswig and Holstein......

Of course, Marin's "silver coins" contain only lead, tin, and copper, and no silver at all, which is a complete fake......

However, from the outside, you really can't see it. Even in terms of hardness, it is relatively difficult to see. Because, part of the copper is added to the currency......

When it came time to mix, Marlin was surprised. The melting points of lead and tin are more than 300 degrees and 200 degrees respectively, but their boiling points are more than 1,000 degrees or even more than 2,000 degrees. Therefore, copper and they can be fused smoothly. If it is replaced with zinc, although the melting point is higher than that of lead and tin, reaching more than 400 degrees, the boiling point of zinc is low, reaching more than 900 degrees, it will be volatilized into zinc vapor, 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 succeeded in developing a "silver coin" that did not contain silver. Then, Marin directly ordered the production task - to mint 2 million Danish finnighs and hit the Danish market......

The Marin Mint produces vintage coins that cost very little because they do not contain high-priced silver. Even, the price of lead and tin is lower than copper at this time. Therefore, the cost of this counterfeit is lower than that of silver-copper alloy counterfeits. The production of 2 million pieces will make Marin a lot of money......

The only drawback of this counterfeit currency is that it cannot encounter high temperatures. Once it encounters a high temperature of nearly 200 degrees, the currency will soften and even liquefy. However, in these days, no one usually goes crazy and throws coins into the fire. The small high temperature of more than 100 degrees is still not exposed. Only the nearly 200-degree high temperature of the fire can try to solve the problem. By the time the counterfeit money was discovered, Marin had already finished shipping. If it is really discovered, it will be the Danish market that will be confused in the end. And that's exactly what Marin wants to see......
