Chen Yixin did almost the homework during the day, and did the rest at night, and there was still some time. She poured out the copper coin and began to slowly discern it.

Ordinary copper coins are the same, and you can see it at a glance. Only some of the different text patterns were put on the other side by her.

After sorting out for about an hour, I almost divided all the copper coins, and there were twenty or thirty coins worth pondering, and four of them were very different from the others.

She wrapped four in crepe paper, put them in a small cloth pocket, and stuffed them into the innermost part of the desk drawer. The rest took a cloth bag and put it in a school bag.

She didn't plan to take the four with her, but just copied them according to the patterns on them, intending to check what kind of writing they were.

It's so easy to read novels and write about people's leaks, but in fact, not many people really succeed. Let's just talk about these copper coins, she estimates that one or two of them can be sold for a little money, and the rest are too heavy to give away.

When he went to school in the morning, Chen Yixin found an opportunity to call his uncle on the way and asked him to pick him up at noon to go to the library.

Computers are not widely available these days, let alone the Internet. Those Internet cafes are also a local area network, and if you really want to go online, you have to go to the Internet café next to the university, and it will definitely be too late in time.

On the other hand, the closest place to the school where you can borrow a computer to search is the city library.

Although it can only be found on the library's intranet, it is already the most convenient channel.

The library has an antiquarian room, which is not allowed to be entered by ordinary people. Chen Yixin took his student ID card and grinded with others for a long time before he was allowed to check it only on the computer outside.

But then she couldn't find out what she wanted. After all, there is no picture recognition function at this time, unless she can first determine what kind of text those twisting patterns are, and then she can retrieve them according to this line.

After entering, she first searched for books on copper coins on the intranet and found two books with pictures.

One is the "Little Dictionary of Ancient Coins" and the other is "Illustrated Ancient Coins".

According to the location of the retrieved books, the two books are on the same shelf, and there are not many people who borrow them.

A library card can only be processed with a deposit. Chen Yixin has no money, so he can only take a look at it here first.

She took out the copy paper from her bag, placed it on the bookshelf, and flipped through the book to see if there were any coins with similar patterns.

As soon as I turned a dozen pages, my eyes were a little confused. However, the noon time was short, and she couldn't ask for leave in the afternoon, so she could only cheer up and continue to read.

"Little girl, you're Jinwen. ”

There was a sudden sound next to him, which frightened Chen Yixin and almost hit the wooden bookshelf.

"Slow down, slow down, don't be afraid, I'm not a bad person. ”

Chen Yixin raised his hand and rubbed his forehead, and turned to look over. The person who spoke was wearing a short-sleeved shirt, dark blue trousers, and a pair of glasses, and looked very polite.

"I see that the words on your paper should be Jinwen, and they are the words on the copper coins of the Jin Dynasty. ”

Hearing what the other party said, Chen Yixin blinked, feeling that he was lucky, he should have met a nobleman.

"Well, I went to buy copper coins, and when I came back, I found a few different, and I thought it might be worth some research, so I wanted to come and find information. ”

The man smiled in a low voice: "The little girl also learns to pick up leaks? ”

He pointed to the study area next to it and led the way in that direction.

Loud noises are not allowed in the library, and you have to find a place where there are few people and no one else is affected. The study area is next to the lounge, and whispering will not disturb others.

"These three are the copper coins of the Jin Dynasty, two Tongbao, and one heavy treasure. As for whether it's true or not, you have to see the real thing to know. As for these two, they should be imitations, and even the year name is wrong. ”

Chen Yixin blushed, explained in a whisper, and finally stuck out his tongue and said nothing.

"If you believe me, little girl, show it to me. ”

The man introduced himself as an associate professor of history at a university in the province, specializing in paleography.

"My nephew, like you, likes to go to the antique city to buy copper coins. That's true, but it's okay to learn from it, and it's not appropriate to make a fortune with it. ”

Professor Zhang gently persuaded Chen Yixin not to pin her hope of making money on picking up leaks, and at her age, learning was the most important task.

"I know, I'm just a little curious, I won't in the future. ”

"It's not impossible, but you've got to be older. Playing with antique coins is very expensive, you are still a student, you have no source of income, and it is not good for you to enter this business too early. If you are just interested in learning about this, you can come to our school library to read books or listen to the professors' lectures. ”

Professor Zhang said a few words without saying any more, but only looked at the paper and found the corresponding pictures from the two books to teach her to identify.

"It's not early, you still have to go to class in the afternoon. It's better to put your student ID on me, and I'll help you lend these two books. When you want to return the book, just give me a call and make an appointment to exchange it here. What do you think?"

Chen Yixin originally wanted to say that he could let his uncle get a library card, but after thinking about it, he nodded and agreed.

Professor Zhang is obviously very familiar with the antique business, and the professor of the Department of History has his own circle, if the copper coins in her hand are real, maybe she can sell them with the help of Professor Zhang's channels, let alone 350,000 yuan, even if it is 10,000 or 20,000 yuan, it will be too profitable.

Professor Zhang wrote her name and phone number to Chen Yixin, and took her to the borrowing office to register, making sure that she and her uncle drove away before going back to continue reading.

"Who is that person just now?" Liu Bin glanced at his niece worriedly, for fear that she would meet someone with ulterior motives.

"It's Professor Zhang from the provincial university who helped me borrow books. ”

Chen Yixin thinks that he still has two points of vision when looking at people, and Professor Zhang is very different from those professors who later sold their reputations in terms of temperament.

A person's upbringing can be distinguished by his speech and behavior. There are well-dressed birds and beasts, but after all, they are a minority, and she is not really an ignorant little girl, whether a man's eyes are clear or not, she can still tell.

Professor Zhang roughly judged that the coins in her hands were "Zhenyuan Tongbao" and "Yuanguang Chongbao", and as for the value of these two copper coins, there is no strict market pricing, only depending on how much the buyer is willing to pay.

Chen Yixin thought about it again and again, and decided to ask his uncle and Sun Chao to go to Professor Zhang with copper coins. She can only gamble on Professor Zhang's character now, after all, even if she sells it in the antique market, they have no connections, so maybe it is not as stable as Professor Zhang's side.

After making a decision, Chen Yixin didn't continue to bother with this. She hasn't studied hard for more than a week, and she is going to take the monthly exam again after a while, and it will be a shame if the exam is too bad.

Looking up at Wei Zhong, the other party was immersed in his own world at all, and he only had questions in his eyes, and he felt a little crazy by brushing the questions.
