My system is not decent

Chapter 230 There is no door to hell, only people call themselves

There are many ways to identify silver coins, the relatively simple method, and the use of tools for identification. For example, on a certain treasure website, there is a silver coin authenticator for sale.

When the silver dollar authenticator touches real silver dollars, it will have the ability to absorb.

Lay the counterfeit on the ground flat, and then suck it up with a silver dollar appraiser, which will turn the counterfeit on the street. However, this appraiser can only identify whether the silver dollar contains silver.

If it is real silver and counterfeit, the silver dollar authenticator will not be able to identify it.

This kind of silver dollar authenticator has a lot of bugs. Some silver dollars of the Republic of China, because the mint cut corners and materials, the silver content did not meet the standard, so the silver dollar authenticator will be identified as counterfeit coins.

However, the silver dollar that was identified as a counterfeit coin was also a silver dollar in the Republic of China, so this kind of silver dollar authenticator played an auxiliary role for novices, but it was of no use to veteran silver dollar appraisers.

In addition, due to the silver content of Yingyang or Longyang, it is difficult for the authenticator to turn it over.

These methods are relatively simple. To identify whether a silver coin is genuine, the most important thing is to look at the text and image.

This point is very professional, just look at the font and avatar of the silver dollar.

What year are these characters made? If they are old coins, they will be more beautiful and the characters will be more three-dimensional, and the engraved fonts will be sharper.

The text on real silver and counterfeit coins will be more swollen and not three-dimensional.

"I didn't expect that so many things would be involved in the appraisal of such a small silver coin!" Zhang Qianshan was a little emotional.

"It's too difficult!" Zhang Yijie was a little dumbfounded. He felt that he understood just now, but after thinking about it carefully, he didn't remember much.

Now, facing the silver coin in front of him, he still has no clue.

Instead, it was Li Jinli, whose eyes lit up when he heard it.

In fact, Chen Wenzhe had already said it, but now he just said it superficially, the real high imitation identification is even more difficult.

"You follow Xiao Li to study hard and see others? Usually you just hold the book and read it when you have nothing to do. Now when you listen to Wen Zhe's explanation, he will understand. You are all college students. Why are you so bad?" Aunt Zhang looked at Zhang Yijie , I kind of hate the way that iron is not steel.

They are all classmates of Chen Wenzhe, why didn't Zhang Yijie learn much?

Chen Wenzhe could only shake his head helplessly. This is talent, and it cannot be forced.

"Actually, the easiest way to identify silver dollars is to look at the side teeth."

Looking at the side teeth is the most important way to identify silver dollars. The side teeth of old silver dollars are relatively deep and natural.

The fake silver dollar is slightly shallower. The general number of side teeth is 178 teeth, and the inner teeth are 100.

Of course, the identification of side teeth in silver dollars is also the most difficult and requires a certain amount of experience.

Experience can be accumulated, as long as you look at a few real coins, you will always get enough experience.

I did Zhang's family a great favor, Zhang Qianshan insisted on a treat, but Chen Wenzhe had no choice but to have a meal.

I didn't go far, and I ate in the scenic spot outside the Antique City. The price is not cheap, and the dishes are not many, but they are still delicious.

After a meal, it was already nine o'clock in the evening.

At this time, Chen Wenzhe couldn't do anything. He originally planned to restore the Kangxi blue and white cloud and dragon pattern pen holder, but now he ran out of time.

There was no other way, so he brought back some food for Li Jinli, closed the store, and went back to school.

"I didn't expect that kid Li Jinli to be really capable!"

Zhang Yijie drove Chen Wenzhe's car, and the two of them hurried back to school. On the way, Zhang Yijie said with a smile.

"After leaving school, I changed a lot, so I should be a reliable person."

"You are also bold. The gold bracelet with such a high value was actually handed over to him for management."

"There's nothing I can do about it. My elder brother doesn't care about it, and I don't have any manpower available. Besides, it's easy for him to run away with only ten bracelets. I won't be injured, but after he did this , this life will be ruined.”

In fact, Chen Wenzhe didn't say some things. What he did was, on the one hand, he had no choice but to test Li Jinli on the other hand.

Using money to test people's hearts is the most unreliable and the best mirror for demons.

Now Li Jinli can earn hundreds of thousands a month, depending on whether he is a smart person or not.

Smart people know how to keep flowing, but fools only focus on immediate interests.

Besides, Chen Wenzhe has another layer of protection!

He didn't tell anyone, but he actually bought Xue Jianming's security service for a long time.

After returning to school, Chen Wenzhe got busy. He needed to control the temperature of the four gas kilns.

Of course, he doesn't need to look at the kiln himself, but the temperature of the kiln mouth needs to be controlled by him.

After a busy night, he didn't sleep for a while until three o'clock in the morning.

In this way, for the next period of time, it can be said that every day is classes during the day and kilns are fired at night.

He didn't say that he went home or went to the store, even if he was repairing the Qianlong blue and white pen holder, he took time to repair it.

It is still very troublesome to restore this piece of porcelain. It is not incomplete, but when repairing and bonding, a part needs to be removed.

Because after splicing butt joints, mud needs to be filled for bonding. If a part is not removed, the cloud dragon pattern on it will not be coordinated.

To remove a part and add a part of the mud tire, it needs to be glazed and colored again.

This is the troublesome place, otherwise, not everyone can use the heat bonding process to perfectly restore a piece of porcelain?

They have been busy for more than a month, and it will soon pass May [-]. A batch of Longquan kilns in their hands also need to be delivered to the Haihai City Museum.

And until May [-]st, there is still more than a month left, and Chen Wenzhe will enter his senior year, and he will have an internship this semester.

At that time, he doesn't need to stay in school every day, so he will have time to do his own things.

For example, go to the store, such as go to the basement of your home, and burn some things you like.

On this day, the affairs of the school were almost settled. Chen Wenzhe walked out of the ceramic research center building with a green-glazed beauty holding pot that he made.

"Huh? Student Chen, where are you going?"

Tong Jianjun once again blocked Chen Wenzhe outside the Tao Research Center building.

"Boss Tong? Are you here to see Professor Tao?" Chen Wenzhe said with a smile.

The Qianlong blue-and-white cloud-dragon pattern pen holder he repaired last time has already been delivered, and the money has also been received.

I just don't know what this guy wants to do when he appears here.

"Looking for you, why don't we go out and find a place to have a cup of coffee?" Tong Jianjun also said with a smile.

"Let's talk about it here, I still have something to do today."

"Let's make a long story short. I still have a small blue-glazed bowl from Longquan kiln in my hand, which is a remnant vessel. However, the bottom of the bowl is well preserved, and the wall of the bowl is missing a third. I hope that classmate Chen can help me repair it. The level of a pen holder is fine."

Chen Wenzhe fell silent. Does this guy know what it means to send sheep to the tiger's mouth?No, it should be that there is no gate to hell, only people call themselves!
