Chapter 23 [23] Who Is Testing Whom?

The copper coin that Master Zhang took out had four small characters "Jianyan Yuanbao" written on it. Due to its age, the handwriting has been worn out and is not very clear.

Before Tang Feng could speak, Qin Yanan on the side spoke first, "Master Zhang, isn't this question too difficult?"

She thought she had some knowledge of antiques, but when she saw this copper coin, she was also confused.

She didn't even know which dynasty this copper coin was from.

There were so many dynasties and emperors in the history of Longguo, and so many era names were changed.

Unless you have an in-depth study of ancient coins, it is impossible to know the copper coins of each era name.

This question is too difficult!

Master Zhang took a sip of the teacup and smiled faintly, "Since he is going to take over the position of the chief appraiser of Yayuan, the question will naturally be more difficult."

"Of course, if you can't answer this question, I can change it to a simpler one for you."

As he said, he was about to take back the copper coin.

But Tang Feng had already reached out and picked up the copper coin, "Let me try."

Master Zhang glanced at him, "You can search online or look up ancient books. There are books about ancient coins on the shelf over there."

Tang Feng was speechless for a moment.

Who is he looking down on?

Does he need to search online and look up ancient books?

What he needs is the system.

Without saying anything, he directly turned on the scanning system.

"System scanning..."

A moment later, all the information about the copper coin was presented in front of him.

At this time, Qin Yanan had already taken the book "Research on Ancient Coins of Dragon Kingdom" very considerately, "Xiao Tang, Master Zhang said that you can look up information."

Tang Feng just glanced at the book and smiled and shook his head, "If even such a simple question requires reading a book, then I have no face to take over the position of chief appraiser."

"Uh..."

Qin Yanan didn't expect that her kindness was taken for granted, and she smiled bitterly.

Master Zhang put down the teacup in his hand and looked at him, "Since you said this question is simple, I will give you half an hour to observe and judge. It should be enough, right?"

Tang Feng put the copper coin back on the table, "Half an hour is not needed. I can give the answer now."

"Oh?"

Master Zhang picked up the teacup he had just put down, hiding his surprise, "I would like to hear more details."

Tang Feng pointed to the copper coin, "Jianyan is the first year of the Southern Song Dynasty, and this year was used for a total of four years. In addition to Jianyan Tongbao, Jianyan Tongzhong and Jianyan Yuanbao were also minted. Especially Jianyan Yuanbao, which is very rare in the world and is one of the fifty treasures of ancient coins..."

Qin Yanan listened to him talking and hurriedly turned her head to look at Master Zhang, and found that he was listening with his eyes closed and nodding from time to time.

It can be seen that what Tang Feng said is completely correct.

This can't help but make her feel very surprised.

In such a short time, he can actually describe the origin of a very rare copper coin like a treasure.

This knowledge and historical background are really admirable.

Master Zhang also smiled a little more and nodded slowly, "It seems that you do have something."

"But it's not enough to just tell the origin of this copper coin. You have to judge the authenticity of this copper coin and give the reason for the judgment."

"This copper coin is fake." Tang Feng did not hesitate and immediately gave his own judgment.

"Oh? What's the reason?" Master Zhang's face was even more surprised and continued to ask.

Tang Feng picked up the copper coin again and continued to repeat the system's scanning results, "I have to say that this copper coin is very realistic, whether it is patina or font, it is impeccable. But it has a very obvious mistake."

"What mistake?"

"Hole!"

"Huh? Hole? What's the problem with the hole?"

His answer obviously exceeded Master Zhang's expectations. He hurriedly took the copper coin from him and looked at the hole in the middle, but couldn't see any problem.

"Sister, can you make me a cup of tea? I'm a little thirsty."

Tang Feng did not answer immediately, but turned to Qin Yanan and said with a smile.

Although Qin Yanan wanted to know the answer immediately, she finally suppressed her curiosity and ran to make him a cup of tea.

After Tang Feng took the teacup, he took a sip like Master Zhang just now, with a look of enjoyment on his face.

Master Zhang had the urge to hit him, and hurriedly asked, "Tang boy, you should tell me quickly, what's the problem with this hole?"

Tang Feng saw that the old man was anxious, and he didn't dare to keep it a secret. "When the ancients used copper coins, they strung them together with ropes. So the holes of ancient copper coins will have traces of natural wear."

Master Zhang immediately pointed to the hole on the copper coin, "No problem, the hole of this copper coin also has traces of wear."

Tang Feng smiled immediately, "This is the problem."

"What's the problem?" Master Zhang didn't understand what he meant.

"Because this Jianyan Yuanbao has only been in circulation for four years, even if there are signs of wear and tear, they are probably very slight. But the wear and tear on this copper coin is very serious. Obviously, the counterfeiter forgot about this and made things worse." After Tang Feng finished speaking, he took a sip of the teacup again and looked at Master Zhang with a smile, "Such an obvious mistake, you should have noticed it before, right?" "Uh..." Master Zhang blushed, although he had also noticed that this copper coin was fake before.

But that was after more than a week of repeated research, and it was not found from the hole.

Tang Feng only took a few glances and picked out a mistake that he had not noticed before.

This immediately made him feel ashamed.

"Even if there is a problem with the hole..." He was about to find some bones in the egg.

Tang Feng had already spoken first, "I know that a hole alone is probably not enough to prove that the copper coin is fake."

"In addition to the hole, there are also problems with its calcification, oxidation, and bone rust..."

He began to pick up the copper coin and explain the problems one by one.

And Master Zhang sat next to him and listened quietly, like a primary school student.

Qin Yanan thought this scene was a bit funny.

Who is testing who?
