Generally speaking, the knives, cloth, and round coins of the Pre-Qin period were all mute.
Coins made after the Ming Dynasty are relatively recent and have not yet been deeply oxidized, so their sound is crisp and loud.
If we throw a pre-Qin coin on the ground and hear a crisp sound, then the coin is not reliable;
On the contrary, if the coins of the Ming and Qing Dynasties are thrown to the ground and make a mute sound, there will be doubts.
The ancient coins of the Five Dynasties must be mute, which is difficult to fake.
So when Li Mingsheng heard this, he narrowed his eyes, this time it was real!
"When doing something, you have to do a complete set, and then identify it based on the version and smell!" Xiao Xiangqi suddenly said.
"Okay, Lao Xiao, you have such ability, why did your apprentice get punched in the eye instead?" Li Mingsheng said with a smile.
Xiao Xiangqi sighed helplessly and said: "If he hadn't been taught this knowledge, he wouldn't have been able to get his eyes opened. He would have had his eyes opened and taken medicine because he was too confident!"
After hearing this, several professors sighed. It seemed that such a thing might have happened to them.
"No more talk, let me smell it. Actually, this point is redundant. Xiao Chen is a master of distressing!" At this point, Li Mingsheng laughed.
He suddenly thought, if this coin was made by Chen Wenzhe, could they identify it?
However, he was also confident enough in his ability to distinguish authenticity by listening to sounds. He really didn't believe that someone could make the mute sound of ancient copper coins.
He shook his head to get rid of the distracting thoughts in his mind.
It is also very simple to identify ancient coins by smelling them.
It can be said that this method is the simplest one in the identification of ancient coins.
Because counterfeit coins are mostly forged and decorated with chemical substances, they often emit an unpleasant, pungent chemical smell, while genuine coins do not have this smell.
Therefore, Li Mingsheng thought it was unnecessary. If the flaw could be found so easily, the coin would not be exposed to everyone.
As for the version, the most important way to identify ancient coins from the version is that in addition to reading more money records, you must have more contact with real objects to familiarize yourself with the authentic coins of each dynasty.
Not only should we pay attention to rare items, but also a large number of common varieties.
Because these ordinary items are rarely counterfeit, they can truly reflect the characteristics of coins in various historical periods.
For example, during the Warring States Period, the shape of the knife cloth was special, so counterfeiters had to use genuine sand to make fakes. The flaws were that the sand-cast coins were smaller and thicker, with superficial characters, rough copper, incorrect rust color and easy to fall off.
Such sword coins are not uncommon for Chen Wenzhe!
Moreover, when the knife coin is minted, its gate is on the knife ring, and the gate of the cloth coin is at the head end. There is basically no need to modify it after it is released, and it remains in its natural state.
Counterfeiters often smooth the edges of knife coins and cloth coins in order to make them look beautiful. In fact, they are superfluous and expose flaws.
Now that the Internet is developed, Chen Wenzhe has watched many videos on identifying various silver coins and copper coins.
For example, the Guangxu silver coins of the Qing Dynasty and Yuan Datou, which were the hardest hit areas for silver coins, were all said to be silver coins, but they did not say anything about the genuine silver coins and counterfeit coins.
And the prices of each one are very high, the lowest one is more than one thousand, and the price can easily be three thousand or five thousand.
There are also copper coins. If you take one out, they are big money. People with small money are not rare.
In reality, how can you find so much money?
You picked up five or six pieces at once? There were even dozens of pieces that slipped out in one fell swoop. Is this possible?
You know, a lot of big money is carved mother money, sample money, commemorative editions or simply money, support money. This kind of money is originally a minority, even in the era of issuance, it was very small, and it is even less popular now.
It's just because it's rare that the price is high. If you can find so many of them at once, how can it be valuable?
Not much to say, Chen Wenzhe and Zheng Yu stole the show this time.
Da Qi Tong Bao, which is out of print in China, has almost been confirmed.
There are four or five experts here, and none of them can find any flaws, which is a good thing.
As for the missing character "Qi", with modern technology, it is not difficult to confirm what character it is.
Not to mention that there are still some remnants of this copper coin. Even if it is covered up, as long as it once existed, you can still see it.
Today's technology can take the rust together and form an unknown object. Through machine scanning and software restoration, you can clearly see the original appearance of the object, and even some tiny handwriting can be clearly seen.
The dating research of the Institute of Scientific Research of the Chinese Academy of Sciences is also very clever.
Putting all these together, Chen Wenzhe's missing characters are all in perfect order, so there is really no way to say there is anything wrong with it.
"Are we witnessing the birth of the first Daqi Tongbao in the country?"
Until now, Professor Li Mingsheng still can't believe it.
"Xiao Chen is amazing. After being transformed, he can still recognize this coin. It's not easy!" Fan Jiaxuan said with some admiration.
"Xiao Chen, can this thing get out?" Xiao Xiangqi said with eyes shining.
It can be seen from his student's purchase of the original silver coin that Xiao Xiangqi also likes to collect ancient coins, which is now confirmed.
"Can such a thing be sold? Xiao Chen is not short of money either!"
Before Chen Wenzhe said anything, Professor Li Mingsheng became unhappy.
"Excuse me, this is an exchange meeting, not a trade fair!" Professor Mu Kairong said.
"Why can't we trade? Isn't it normal for us to exchange and trade after looking at something?" Xiao Xiangqi said.
"Bartering is fine, but money transactions are not, as they can easily lead to problems." Mu Kairong said seriously.
"Okay, okay, this exchange meeting is not very formal. No one should care about it. Lao Mu, you are the only one who has no performance today. What's the matter? Why don't you come up with something for us to see?
"
Mu Kairong smiled: "I and the things are not simple, we have to pay close attention to them."
After saying that, Professor Mu Kairong carefully took out a scroll from his satchel.
"What is it? You are so cautious?" Seeing Mu Kairong's actions, Xiao Xiangqi immediately laughed.
"Good stuff, when you see it later, your jaws will definitely be shocked, and at least your eyeballs will fall all over the place!"
After finishing speaking, Mu Kairong took out the scroll and placed it carefully on the table.
After putting it down, he also tidied the tablecloth on the table. When everything was ready, he slowly untied a small rope and slowly opened the scroll.
"A calligraphy? Treat it so seriously. It seems to be an authentic painting by a famous person?" Or was Xiao Xiangqi cooperating?
However, no one paid attention to Xiao Xiangqi's performance at this time, but focused all their attention on the words in front of them.
Chen Wenzhe was no exception. He just glanced at it and realized that this word was really not simple.
Although only a few words were leaked out, these few words made him feel refreshed.
