Before Zhao Tianming got his hands on it, he knew the specific information of the ancient coin, compared to his ancient mirror, the scientific analyzer ordered by Pang Zhonghua was a child's toy, too low-level.

He took the ancient coin in his hand and looked at it for a while, about half a minute.

I saw him lightly put the three-hole cloth on the table, and his cautious action made everyone a little confused. Isn't it just a fake?

Some people even think that this person is so fake! Such a move may just be to improve his own image, so that others can see that he is a person who respects others, and even if it is a fake, he cannot be thrown around and appear to despise the treasure-bearer.

Zhao Tianming looked at Xiao Zheng on the stage with a smile: "Classmate Zheng, we meet again." ”

The host was surprised and asked, "You know each other?"

Since they know each other, why do they have to take it here for identification? This time it's okay, right? Fake, how embarrassing? If they were, they would definitely look for Zhao Tianming first, so they didn't have to be so troublesome.

Xiao Zheng cleaned up his lost emotions and squeezed out a smile: "Brother Zhao, I really didn't know that you were an expert in treasure appreciation." ”

This time, you understand.

Emotional acquaintance is acquaintance, but I am not familiar enough, I don't know that people will appreciate treasures, no wonder, I came to the show with a fake.

Up?

Old man Hao, they don't want to see this scene, they should continue to comment on a fake! Let's see what Zhao Tianming can say.

"It's okay! Isn't that known? If there is any treasure in the future, just look for me. ”

Old man Hao couldn't help but interrupt this boring topic: "Xiao Zhao, tell someone about this ancient coin!"

Zhao Tianming still didn't understand what bad intentions this old man had? He smiled secretly in his heart: Old man, you are digging a pit for yourself!

And Pang Zhonghua also came to join in the fun, before Zhao Tianming grabbed the position, and then asked him to put a place, he can look at that guy pleasing to the eye. Whenever he gets the chance, he's certainly happy to step on it.

"Yes! Xiao Zhao, let me tell you! Your eyesight is well-known in the industry, who doesn't know about your peers in the province?"

"Not only in the province, but also in the country, it is not small!" Old man Hao continued.

These two guys just want to kill people!

Zhao Tianming was speechless: After a while, you will know what it means to move a stone and shoot yourself in the foot!

He hurriedly waved his hand: "Both of them are seniors, you can't talk nonsense, I'll be a nameless junior." ”

Nobody?

Haha! It's not rampant this time? You kid is also afraid? Now it's an appetizer, and there's a big meal waiting for you later, don't worry!

But Zhao Tianming's words changed: "Of course, eyesight is a little." Since the two seniors are so gracious, let me say a few words, then, let me say a few words!"

"First of all, this is a very old currency, everyone knows it, right? In terms of style, it is a cloth coin from the Warring States period. Speaking of which, I would like to remind collectors not to fall into a misunderstanding when collecting ancient coins. ”

The host also cooperated with Zhao Tianming once: "What misunderstanding?"

"In the world of ancient coin collecting, there is often a misconception that many new collectors will think that the older the old coin, the more valuable it is. Zhao Tianming said.

In fact, to determine the collection value of an ancient coin, the most important thing is to look at the number of surviving people, and then from the technical process and the texture and quality of the coin to make a comprehensive evaluation, just looking at whether the casting age is old is not enough to make a conclusion about the value of an ancient coin.

He told everyone that the main factor affecting the value of ancient coins is their own survival, and the general law of "rare is expensive" in the collecting world also applies to the ancient coin sector.

Some dynasties in history are relatively strong, and a single variety of coins have been issued for decades or even centuries, so the number of such ancient coins is very huge, and some short-lived dynasties have just tried to mint some pattern coins that were changed to the dynasty, and the number of such ancient coins is naturally very small. This has a direct impact on the investment value of ancient coins.

"Everyone knows this, Xiao Zhao, let's talk to the big guy about being more practical!" Old man Hao made a stumbling block.

Zhao Tianming glanced at the old man and said with a smile: "What I am saying now is very important, don't believe it, you ask the audience present, do you have such a misunderstanding?"

"In addition, this is closely related to what I am going to say next, and I still need to mention it. ”

"Oh, then you say!" Pang Zhonghua had an expression of watching the play.

Anyway, the thing has already been beaten to death by him, can you still make it turn over?

Old man Hao was pushed by Zhao Tianming, obviously a little unplayable, and his face darkened.

"Then you continue!" Old man Hao watched Zhao Tianming die by himself.

"So, if this ancient coin is real, Xiao Zheng, you will be rich. ”

"Isn't that nonsense?"

As soon as these words came out, Zhao Tianming's face was not good-looking. This old guy is a bit too much! Interrupting others like this three or four times, and it is still a very shameful remark.

The others were also nervous, for fear that Zhao Tianming would make a big fuss.

And Old Man Hao was also hot in the brain just now, and he didn't think about it. As soon as the words came out, he reacted, and he seemed to be a little too eager for revenge.

In the eyes of others, he has a bad image of being very impolite and disrespectful.

He hurriedly remedied: "Xiao Zhao, I didn't mean you, don't sit in the right seat." ”

Hehe!

As soon as these words came out, many people felt that this old man spoke without thinking. Isn't it more "there are no three hundred taels of silver here" to explain it this way?

Zhao Tianming looked at him deeply, and only turned his head away until the old man was looked at him weakly.

"Ancient coin counterfeiting is nothing more than that. First, sand turning method, second, re-engraving method, third, embedding method. ”

"The so-called sand turning method is the earliest method of counterfeiting ancient coins, which generally adopts the method of recasting the mother money, and rarely uses money to forge. In ancient times, when coins were minted, the whole box of mother coins was put into the sand box, so the sand mold pressure was uniform, and the thickness of the coins minted was the same. Zhao Tianming said to everyone.

As for the re-engraving method, there are two kinds, one is to use gilt copper to re-engrave, and the other is to re-engrave the original money.

"The inlay method is another important method of numismatic counterfeiting. The traditional embedding method includes digging and patching, spelling, and fighting. ”

Ancient coins often form some special varieties due to misalignment or transgression, such as the closed back, which is less common than ordinary coins due to the negligence of the foundry, and is an indispensable collector's variety.

Counterfeiters take advantage of this by grinding two coins very thin and gluing them together to create a rare fit or face.

It is difficult to observe counterfeit coins in this way, whether they are written or rusted, but when they are gently thrown on the countertop or on the ground, the sound produced is not as pure as that of real coins such as closed backs.

"So, two seniors, say that this is a fake, where to start? Don't talk about patina, this patina is obvious, it was forged later. However, you can't make it a fake with a hammer, right?" Zhao Tianming began to fight back.

As soon as these words came out, there was an uproar at the scene!

Interesting!

Anyway, everyone is watching the fun, if the recording process of the show is all harmonious, what else is there to see?
