Pang Zhonghua smiled at Zhao Tianming, but Zhao Tianming could see that there was something insidious in it. And Old Man Hao also smiled, blatantly gloating.

Didn't you have a good time with us just now? This time, let you taste it too.

The ancient coin was quickly delivered to Pang Zhonghua. Pang Zhonghua is still the same, according to his means, first use scientific instruments to measure the substance itself.

No matter what you become, your essence cannot be changed.

For example, if an item belongs to a dynasty to which its material composition belongs, it is that dynasty, and it is almost impossible to falsify the material year.

What can be used is only the appearance of the object.

Therefore, the pursuit of essence is the core identification idea of Pang Zhonghua. All his abilities are based on the matter itself, and whether it is true or false can be figured out by relying on instrument measurements.

The scientific instrument in his hand was the year when he spent a lot of money and had people customize it abroad, and it could be used for preliminary analysis of substances.

It hadn't been two minutes before he put down his instrument and threw the ancient coins on the table. Everyone was shocked, this kind of performance is almost a conclusion, it is a fake!

On stage, Xiao Zheng also felt a sudden burst in his heart, feeling that his heart was about to stop beating.

"Let me say a few words! First of all, ask the treasure bearer, do you know why this coin is called cloth?" Pang Zhonghua asked.

Yes?

Xiao Zheng really doesn't know why it's called three-hole cloth, three-hole can be understood, but why is it called cloth? Obviously, it's copper, iron and other metals.

"I don't know, right? Let me tell you! During the Spring and Autumn Period and the Warring States Period, coins were usually called cloth coins. ”

Cloth coins, also known as shovel cloth, evolved from bronze agricultural tools and plutoniums, and are shovel-shaped copper coins that circulated in the Central Plains during the Spring and Autumn Period and the Warring States Period in China. Shovel-shaped tools used to be a medium for private transactions, so the earliest coinage was minted in the shape of a shovel.

The original cloth coin, which retains its appearance as a tool, retains a chisel with a handle, is primitive and heavy, and then gradually lightened, thinner, and smaller, and the body of the coin becomes completely flaked, making it easy to mint and carry.

"Cloth means linen, and linen is also one of the medium of exchange. When copper coins appeared, people still called copper coins cloth because of the influence of long-term habits. Pang Zhonghua said.

Cloth coins can be divided into two categories, namely empty and flat. Among them, the empty head cloth can be divided into flat shoulder arc foot empty head cloth, oblique shoulder arc foot empty head cloth, shrugging shoulder pointed foot empty head cloth; flat head cloth can be divided into flat head cloth, acute angle cloth, square foot cloth, pointed foot cloth, round foot cloth, three-hole cloth.

"The most precious of these cloth coins is undoubtedly the three-hole cloth we mentioned. Look, everyone can see, that's it. He picked up the coin and held it high for everyone to see.

"If it's genuine. Well, I'm going to congratulate you, you've made a fortune. Not to mention a few years of less struggle, it is no problem to struggle for a few decades. The three-hole cloth once sold for a sky-high price of more than 3 million, and now it is needless to say. Pang Zhonghua said to everyone.

On the stage, the host standing next to Xiao Zheng was surprised: "In this way, it is a fake? ”

Pang Zhonghua also explained to you that contemporary numismatists divide ancient coins into ten grades according to the rarity of various coins and the current numismatic market, namely: first-class treasure, second-class column, third-grade rare, fourth-grade rare, fifth-grade rare, sixth-grade rare, seventh-grade rare, eighth-grade few, ninth-grade more, and tenth-grade multi-pan.

"Three-hole cloth is listed as a first-class treasure. You're a decent! Unfortunately, however, it is a fake. Don't look at it rusty, patina, and it feels very old. But, that's all a sign of old-fashionedness. He said.

Zhao Tianming could clearly see the loss on Xiao Zheng's face.

Perhaps, that ancient coin really pinned on his great expectations. As the saying goes: the greater the hope, the greater the disappointment!

The audience at the scene felt pity. Of course, there are also some viewers who can't see the good of others, but when they hear this news, they are relieved and relieved.

"Just now, our old-timer Hao Lao also said that ancient coins are the easiest collector's items to cheat people. There's no shame in falling on your heels here, just pay the tuition! Anyway, it's 20 yuan. In the future, when encountering this rare variety of ancient coins, do not be impulsive and calmly scrutinize. Pang Zhonghua also talked endlessly.

However, he still mentioned Old Man Hao in a friendly way, saving him from embarrassment for a while. As for Zhao Tianming, hehe, hehe!

He continued: "If you don't make it clear, maybe you are still not convinced. First of all, we can look at this layer of patina, and we can make a final decision. ”

"During the Spring and Autumn Period and the Warring States Period, ancient coins were all minted in bronze. At that time, ironmaking was a difficult technology, it was not yet mature, and copper was not easy to purify, so the metal at that time was actually an alloy doped with many medium metals. According to the analysis of the alloy composition at that time, the patina they produced should not be like this. ”

He pointed out that the patina of different periods and different metal compositions behaved.

"Then, the result is obvious, this so-called ancient coin, it is a mass-produced fake, and the cost is less than two yuan. Twenty dollars, a loss. However, I believe that everyone present can afford to lose. ”

After speaking, he moved the ancient coin to the old man Hao next to him: "You come and see." ”

Old man Hao rolled his eyes, what else are the fakes looking at? Isn't this deliberately embarrassing me? This guy is not a good thing, he doesn't know how to respect the old and love the young!

He pretended, glanced at it a few times, and then threw it in front of Zhao Tianming: "It's nothing good-looking, just a fake." Just now, Expert Pang has made it very clear. ”

Old man Hao glanced at the lost Xiao Zheng on the stage, and sneered in his heart: Another daydreamer!

"Three-hole cloth, if I encounter it, I won't even look at it. Do you know why the three-hole cloth was auctioned for more than 3 million yuan a few years ago? It was the only one-of-a-kind piece that was found.

Such a famous ancient coin, if it were genuine, would have been snatched up a long time ago. Ancient coins are too easy to distinguish between precious varieties and tell at a glance whether this type of ancient coin is worth much. If it was a precious variety, it would have been taken away long ago if it had not been checked clearly. ”

Although I also think that fakes are nothing to look at. But he still threw it in front of Zhao Tianming, and asked Zhao Tianming to comment a few words, to see if he was embarrassed this time!

"Xiao Zhao, your eyesight has always been known for being vicious, how many times do you take a look, maybe we hit the eye?"

Yes, anyone can hear that it is disgusting.
