Jingwen was so embarrassed by Di Renjie's little kid that he had no choice but to leave the scene so that he didn't have a headache. Today's children are really getting more and more difficult to teach, Jingwen remembered his situation back then. Raising a child knows the kindness of his parents, Jingwen is so difficult to have an apprentice now, and how his parents raised him to be more than ten years old back then made Jingwen feel a little emotional. But it's useless to sigh now, my parents died when I was more than ten years old in my previous life, what else can I do?

"Master, Miss Cui Ying is here, she has something to look for you. We're out there, though! A domestic servant said.

And Jingwen immediately reprimanded: "You idiot, didn't I say it a long time ago? In the future, Miss Cui Ying and Miss Xiao Wei will come, don't be outsiders, just let them in! ”

"Yes, yes, yes!" The servant said hurriedly.

Jingwen's servants all knew Cui Ying's thoughts, so they were not surprised when they heard Jingwen's statement. But although Cui Ying knew that Jingwen had ill intentions towards her, she kept her distance as much as possible. Coupled with Cheng Lin's opposition, Jingwen couldn't directly force her overlord to the bow. After all, although Cui Ying can't go back to the Cui family, his father is the eldest son of the Cui family. Where is the relationship for many years said that it will be separated, if Jingwen dares to bow hard to Cui Ying's overlord, Cui Tan will definitely fight with him. Although Cui Tan acquiesced to Jingwen's thoughts about Cui Ying, it didn't mean that Jingwen could make her overlord bow hard! is like an old father-in-law, although he can acquiesce to his son-in-law's pursuit of his daughter, but he can't tolerate his son-in-law using his daughter, which is what every father thinks. Therefore, Jing Wen naturally couldn't be Cui Ying, as well as Xiao Wei's overlord, who made them too hard backstage!

Cui Ying was quickly brought in, and then Cui Ying came to Jingwen. said: "Jingwen, the fan of our bank's coinage has come out!" ”

"What do you mean by 'Fan'?" Jingwen asked.

"That's the mold we use to make money." Cui Ying said.

Jingwen then understood that the ancient coinage used molds, and then melted the copper, poured it into the mold, and then cooled it to form a copper coin. Jingwen heard this, and was very speechless in his heart, isn't the cost of minting money very high? Although, the cost of casting money with molds is already much lower than the cost of manual coinage. But there must be a lot of loss in this process, this can be imagined. Every time the copper is melted, some of it is lost, which can almost be said to be certain.

"Jingwen, this is our silver coin, look at it!" Cui Ying said.

Then, Cui Ying handed over a few silver coins from the bank to Jingwen. And Jingwen took a look at these silver coins, which represented the various postures of Emperor Li Shimin. And this one starts with a silver coin. To half a tael of silver, respectively, represent Li Shimin's various life experiences. From the battlefield to the king, in fact, it is also a life biography represented by a few pictures. The pattern of these silver coins. They all invited famous artists to paint, that is, the paintings made by Yan Liben and Yan Lide brothers. Jingwen proposed to promote the image of the emperor, so he made this model of biography. In fact, these silver coins are all the same size. It's just that the thickness is different, which causes the difference in weight.

"Why is this coin so crudely made?" Jingwen asked.

"We can't help it, that's what it looks like with molds." Cui Ying said.

And Jingwen brought a small medicine name again. Then he picked up two silver coins of the same size and weighed them against each other.

"No, no, no, there is a clear difference between the two weights, and it can't be like this. The gap is one or two grams. For a one-dollar silver coin, the difference of one or two grams is already very dangerous. One coin is five grams, but this is a difference of one gram, and I am afraid that the value of these two coins is not the same. If these coins are out, I'm afraid that the bad money will drive out the good money. Jingwen said.

Jingwen, a later generation, certainly knows some economic laws. If the difference in weight between these silver coins is too large, then I am afraid that the people will spend the coins containing more silver first, or use them to exchange for coins that contain more silver, because they all have the same face value. If this is the case, it will probably cause bad money to drive out good money, and coins with low silver content will circulate, while coins with high silver content will be collected. This, in turn, leads to a shortage of silver coins in the market, resulting in deflation.

"Jingwen, there's no way to say this! Our molds are not precise enough, so we pour in silver water, and then it comes out, and that's it. This is how copper coins are also minted. Cui Ying said.

Jingwen shook his head, because this batch of silver coins was not qualified. In ancient times, unlike later generations, credit money was used and paper money was used. The precious metal content of the ancient physical currency also represents the value of the currency, and if there is a batch of money with a relatively high precious metal content, I am afraid it will be collected. Once the collection has formed a trend, it is not conducive to the circulation of money. If this batch of silver coins could not be circulated, then Jingwen's bank planning would be in vain.

Jingwen can also understand that this kind of problem will not occur when it comes to copper coins. Because copper coins are one gram more, one gram less, and the value difference is very small. But now that silver coins are used, the difference between the value of silver and copper is huge. One more gram and one gram less, it was very meaningful for the ancient people. Ancient silver was very valuable, and one gram often represented a big difference. Therefore, the error of the same version of these copper coins must be controlled below one-third of the gram, otherwise it may have a great impact on the economy. At that time, silver coins of the same face value will have different values, and it will be miserable.

"Jingwen, this idea of yours is impossible to come true. Since I am in charge of this bank, I naturally know that the mint cannot be so small. There is a lot of silver melting and fire consumption of molds alone! Cui Ying said.

Jingwen is also thinking about it, and this fire consumption is also a problem. If it is melted, it will definitely produce fire consumption, plus the loss of coinage and so on, and the cost is not low. Minting can be said to be a very profitable thing, if you can save the cost of coinage, then Jingwen's seigniorage can also be more profitable. The ancient emperor didn't realize what seigniorage was at all, and now Jingwen could have the right to mint money, of course, he had to find a way to get the benefits of this coinage. Of course, saving portions from raw materials will not work, and the credibility of antiquity is not so good. Therefore, if you want to save costs, you can only reduce fire consumption and minting costs in the minting process, so as to obtain benefits.

"But how do you save costs and save materials? Moreover, during the casting process, there will be a weight gap! How to solve this? Jingwen also thought a little helplessly. (To be continued......)
