After "observing" for another two minutes, Cheng Hao put the ancient coin back on the table, smiled and said to Wang Chunlin: "Thank you Boss Wang, I've finished reading." ”

Zhao Shuqing said disdainfully: "That's it?" In such a short time, you can see a fart! ”

Even a veteran connoisseur like Wang Chunlin, who has been in the industry for decades, has to have a complete set from beginning to end, what is the first appraisal type, the second appraisal casting process, the third appraisal calligraphy, the pattern ornamentation, and the fourth appraisal material color......

A complete set will take a few hours, to say the least, and the identification may not be accurate.

Cheng Hao has been reading all the patterns for two or three minutes, I'm afraid he didn't even read all the patterns, so he dared to say that he had finished reading them, isn't this nonsense!

Zhao Shuqing was full of contempt for Cheng Hao, thinking that he was a second-rate person who didn't understand anything.

He didn't know that Cheng Hao had this nose that could sniff out the vintage, how could it take two or three minutes, and it only took 1 second to see the truth or falsehood, and it took a few minutes to just make a show!

He only needs to sniff it, and the results measured by the spectral identification instrument are faster and more accurate!

Wang Chunlin didn't have any hope for Cheng Hao, but asked politely: "Little brother, can you see anything?" ”

Cheng Hao smiled slightly, and read according to the consciousness in his mind: "This is the treasure of the Jin Dynasty, it has been more than 900 years ago, this is a real book folded two-type copper coin, with a diameter of 3 centimeters and a weight of about 7 grams. There are 3 known pieces in total, which are extremely rare and highly collectible. ”

Thunder on the ground!

Wang Chunlin's eyes when he looked at Cheng Hao changed instantly.

Due to the extremely long vintage, there are only 3 pieces unearthed at present, the stock is very small, it is a very unpopular collection, it is a small number of small people, there are not many Tibetan friends, and it can clearly tell its origin, limited to the high-end people in the ancient coin circle.

Cheng Hao, a young man, how could he say his name and origin in one breath?

Zhao Shuqing was also taken aback.

Wang Chunlin asked anxiously: "Do you know this heavenly treasure?" ”

"Not only do I know that this is a treasure of heaven, but I also know that one of these two is true and the other is fake."

"Is that true?"

Wang Chunlin's eyes were even more shocked, and his heart was pounding - maybe this young man helped him solve the problem in front of him?

This young man didn't even use a magnifying glass, so after watching it for two or three minutes, he dared to bite the truth and the falsehood......

You must know that if it weren't for Zhong Lao's explanation in advance, he wouldn't dare to be sure whether it was true or false.

Isn't this young man sharp-eyed?

Zhao Shuqing was more suspicious, but his tone was finally a little better: "Young man, if you say big things, you will flash your tongue!" ”

Wang Chunlin asked eagerly, "Which one is real and which one is fake?" ”

Cheng Hao was confident: "The one on my right hand is genuine, and the one on my left hand is a fake, just a handicraft." ”

Zhao Shuqing frowned: "There is no evidence, how do you judge that the right side is true and the left side is false?" ”

Wang Chunlin also nodded fiercely, waiting for Cheng Hao's explanation.

He has been running an antique shop for 30 years, and he has sold thousands of ancient coins, some of which are shoddy and full of loopholes, and he can distinguish the authenticity at a glance, but these two Heavenly Treasures are almost identical.

He and Zhao Shuqing are both experts in identifying ancient coins, but after looking at them for a long time, they can't distinguish between the real and the fake.

How did Cheng Hao tell the truth so quickly?

Cheng Hao told it eloquently (in fact, it was just according to the consciousness in his mind):

"Quite simply, the replica on the left-hand side is indeed very realistic, and at first glance it looks almost the same, but there are still two fatal flaws in the concealment.

First, the green rust on the surface of the imitation is fake. On the surface, there is no obvious difference between the green rust of the two, but if you touch it carefully, you can feel that the surface of the imitation is thicker.

The weight of the two is obviously similar, why is this one thicker? Because this is a new rust made on purpose, it uses lead-free copper, so it is on the light side. So even though it's thicker, it's not much heavier.

Second, listen to the sound - pay attention to the back of the knock, the sound of the four corners of the real product is consistent and uniform when striking, and this imitation, the upper and lower parts are obviously different because of the uneven casting material. The upper part is densely cast, so the sound is more delicate; The lower castings are a bit more sparse, so the sound is more flirtatious. ”

After listening to him say this, not only Wang Chunlin was shocked, but Zhao Shuqing was also shocked.

This...... They didn't see these two flaws at all!

Wang Chunlin glanced at Cheng Hao deeply, put the imitation ancient coin to his ear, and flicked it lightly with his fingers, and the sound of the upper part and the lower part was really different

He handed it to Zhao Shuqing in surprise: "There is really a difference!" ”

They also know and try to distinguish the sound, but they didn't expect that the comparison between the upper part and the lower part will be detailed!

"But this alone ......" Zhao Shuqing was actually shocked, but he still had some doubts.

Cheng Hao saw that the two of them were bluffed but didn't believe it, and secretly laughed: "If you still don't believe it, I can also tell you a simple way to distinguish it." Take it and gently wipe it with alcohol, the surface of the fake will rust, and because it has just been applied, it will have a mildew smell when encountering alcohol. ”

"Wipe it with alcohol?" Wang Chunlin and Zhao Shuqing looked at each other.

In order to prevent damage to ancient coins, they are generally not often wiped with chemical agents such as alcohol......

Cheng Hao saw their worries: "Don't worry, you only need to dip a little bit on it, and there is no high temperature heating, so it won't damage the body of the coin." ”

Wang Chunlin gritted his teeth, went to get alcohol and cotton swabs, and dropped a small drop on each of the two ancient coins.

After a while, sure enough, the green rust of the imitation began to fall off!

Wang Chunlin picked it up and smelled it, and sure enough, there was a musty smell!

This is completely in line with Cheng Hao's statement!

It's incredible!

Wang Chunlin was completely convinced now, looking at Cheng Hao with his eyes like looking at a big man, and he didn't dare to underestimate him anymore.

I thought it was a bronze, but I didn't expect it to be a king!

Wang Chunlin held Cheng Hao's hand tightly and said excitedly: "Little brother, what do you call it, thank you so much!" You've helped me a lot! ”

This made Cheng Hao a little embarrassed: "It's okay, it's okay, it's just a gesture." Just call me Cheng Hao, in fact, I came to Boss Wang with an ancient coin to estimate the price, I don't know if it's inconvenient for you. ”

Solving the problem of Tianjuan Tongbao, Wang Chunlin was in a good mood: "Oh? Valuation? Brother, you also have a collection of ancient coins? Of course, take it out and show it to me! ”

Cheng Hao took out the silver coin of Guangxu ingots wrapped in a handkerchief from his pocket and opened the handkerchief.

Wang Chunlin is a knowledgeable person, and when he saw Guangxu ingots, his eyes lit up all of a sudden: "Guangxu ingots!" If it's true, it's a treasure! ”
