The postal airship landed the four containers in the open space in the center of the factory yard, signed for them, and flew away. Isaac directs workers to transport the machines into the building on flatbed trailers and connect them to the water turbines.

During this time, Roland contacted Sukhoi, who was far away in Baiou Harbor, with a high-grade communication stone, and thanked the old man, informing him that the stamping and minting machine entrusted to him had been received.

The old man Sukhoi did not care much about the simple structure of the stamping machine, but was very proud of the coin encryption pattern he designed, saying that it was a combination of concave and convex and nested embossing technology, and the edge of the processed coin was attached to a circle of exquisite and complex patterns, which was almost impossible to imitate. In order to avoid the wear and tear of the well-designed security pattern, the old man also made the mint a constant mechanism to strengthen the hardness of the forging, and the gold coins stamped by this new type of mint are comparable to the hardness of steel, and they are less likely to wear and tear in the process of circulation.

In the age of gold and silver coinage, who should bear the loss of value caused by the natural wear and tear of the coin? This is a serious problem. If the central bank had a monopoly on coinage, responsible for recovering worn and undersized coins and smelting them into coins of full value, it would be logical for the government to bear these losses. If the government did not want to bear the loss, it was also a logical option to allow private minting and levy a seigniorage to compensate for the wear and tear.

Roland's ban on private coinage meant that he had to face the problem that gold and silver coins were soft and easy to wear, and now the old man Sukhoi helped him solve this problem, saving him a lot of trouble.

After three thanks, Roland ended the call with the old man and turned to Isaac Trifonovich.

Now he finally figured out that this somewhat introverted mint manager was the nephew of the Minister of Industry, Zinovi, a graduate of the School of Mechanical Engineering at the Imperial Central University, who had worked as a manager and technician in the forging workshop of the Zinovi Iron and Steel Works, and was very familiar with the military business of forging armor and artillery, and had also done less legal private work, such as making fake imperial gold coins for Zahar's Far Eastern First National Bank, and was also an expert in the minting industry.

Feeling that he had an opportunity to do what he could do, Isaac rushed to the central bank early the next morning after receiving Zahar's notice, and he was offered the challenging position of manager of the National Mint, of course, with a much higher status than a manager on a factory floor, and a leap in income.

Isaac was not very sociable, perhaps under the influence of Semyon, and he also wanted to try to show himself in front of Roland, and he tried to make a couple of sycophants.

"Your Highness, you have decided to replace the backward coinage technology with stamping technology...... Well, too sensible and very visionary. ”

Roland just wanted to laugh when he stammered and patted his ass, this guy's skills are far worse than Semyon's, obviously he hasn't exercised in officialdom.

"Isaac, tell me more about how stamping and coinage are better than traditional coinage."

Roland intends to give him a problem, but Isaac is a professional after all, and this test is really difficult for him.

"Your Highness, the traditional way of minting coins is very troublesome, first you have to use clay to make 'clay fan', then fire it into 'pottery fan', inject melted metal liquid to cast coins, and then take out the coins and polish them by hand until the surface is smooth and clean." When it comes to his specialty, Isaac speaks with much more confidence, and he doesn't stammer, "The coins minted in this way are relatively rough, the shape and weight cannot be guaranteed to be completely uniform, and there will be a lot of wear and tear in the casting process." ”

Roland listened to Isaac's story, and the history of coinage on Earth came to his mind, and there was a sense of déjà vu.

The minting process of the Ming Dynasty in China on Earth is similar to the traditional coinage process in the world of Vares, and there is also a problem of minting loss, which is the so-called "fire consumption". The fire consumption of the broken silver taels is as high as 2%, and the loss of minted copper coins is about the same rate.

The use of casting method to process coins is not only rough in process, but also difficult to accurately control the weight, and there may be large errors in the weight of the same batch of coins. Once such coinage is in circulation, it encourages the greedy to scrape the edges of the coinage with sharp tools such as knives to obtain a small amount of gold and silver powder for profit. Due to the problem of rough craftsmanship and excessive component error in the coinage itself, it is difficult for people to detect this kind of passive coinage, and most of them can still be circulated in the market, which stimulates more people to join the ranks of "rubbing oil" from the coinage driven by greed, resulting in the rapid depreciation of the coinage due to abnormal wear and tear, and either being eliminated from the circulation market, or being recycled and reminted by the government, for which an additional fee has to be paid, and the cost of man-made destruction of the coin will ultimately be shared by all taxpayers.

If a coin is manufactured by stamping, it is possible to print delicate and intricate patterns on the surface and edges of the coin, which are not only beautiful but also anti-counterfeiting, and if someone tries to scratch gold and silver dust from the stamped coin as they did against coinage, it will inevitably destroy the security pattern and cause the coin to no longer be legally compensatory. If the person does not give up and tries to buy goods in the market with the damaged coin, the store owner not only has the right to refuse to accept it, but also can turn the person to the police station for sanction in accordance with the law. From this point of view, the universal application of stamping and pressing technology is more conducive to ensuring the safe circulation of currency and reducing the loss caused by man-made.

Compared with casting coins, hydraulic stamping forged coins are more advanced and have much lower losses, which can be controlled at 3 thousandths, which is also included in the cost of minting, but in fact at least half can be recovered.

"The central bank plans to produce 100 million gold thalers this year, of which 60% of the funds raised from the issuance of treasury bonds have been put in place, and the remaining 40 million will be in place as soon as possible, and the mint will formulate an annual production plan according to 100 million gold thalers, and the gold dust recovered in the minting process is worth at least 150,000 gold thalers."

Roland never hid money issues, and directly spread out the mint's proceeds to make it clear to Isaac.

"I'll give you this big business, but I won't pay you any extra fees, the recovered gold dust is even your contract fee, this money includes the wages of hired workers, including the taxes you should pay, and the cost of building the factory, and we will use the latest hydraulic press to forge gold coins, a machine converted into fifteen thousand gold thalers, this cost is also paid by you, remove all expenses, the net profit of the mint a year is almost 50,000 gold thalers, well done, there will be opportunities to cooperate in the future, Isaac · Trifonovic, would you like to take the job? ”
