Following Mr. Liu's shout, people outside immediately started to move. After a while, a man and a woman came in holding their belongings.
"Teacher, these are the tools you asked for." The two men respectfully placed a micrometer and a small, exquisite, high-precision electronic scale on the workbench. Mr. Liu casually said, "Don't leave yet. Wait a moment. After I identify this ancient coin, you can help me here."
The two young men showed joy on their faces. The girl in her twenties asked, "Teacher Liu, what treasure did you find?"
Old Liu smiled and said, "We just found a sword of the Qiankun Magic Sword of the Medicine Saint Li Shizhen, and now we have found a Daxia Zhenxing Ancient Spring that is suspected to be the real thing. Xiao Zheng, I will show you this national treasure in a moment."
After saying this, Mr. Liu no longer cared about the two disciples, but concentrated on operating the tools.
After a while, Mr. Liu said excitedly: "It should be a genuine piece without a doubt! The diameter is 23 mm and the weight is 2.8 grams. The diameter is exactly the same as the genuine piece in the History Museum. The weight is slightly heavier by 0.6 grams, but this is not a problem. The Daxia Zhenxing sold in 2004 is more important than this one. The key is that this Daxia Zhenxing should be of the same type as the one in the History Museum!"
The two young men also came up and stood side by side with Yang Jing. Mr. Liu continued, "Take a look at this Daxia Zhenxing. The copper is reddish, and the coin body is covered with rust. The rust is like armor, tightly wrapping the coin body. The rust comes from the bones. The rust can be identified as coins from a long time ago, and it is not a modern counterfeit. From the casting point of view, it is regular and dignified, with a good surface. The coin text "大" is derived from "太", and the regular script contains the rhyme of official script. The writing style and basic shape have the typical characteristics of coins that have been unearthed before."
Yang Jing asked: "Mr. Liu, can we determine whether this copper coin is genuine based on these aspects?"
Mr. Liu smiled and said, "Of course there are more than that. The Great Xia Zhenxing coin was minted by Helian Bobo of the Great Xia during the Sixteen Kingdoms period, that is, from 419 to 424 AD. In the Eastern Jin Dynasty, the Xiongnu noble Helian Bobo established a country called "Xia" in Shaanxi Province in 407 AD. After occupying Chang'an in 419, he established the reign "Zhenxing". The Great Xia Zhenxing coin may have been minted at this time. The shape has the legacy of Mang coins, and the inner and outer contours are fine. The four characters "Great Xia Zhenxing" on the coin are read right-handed, in a semi-official and semi-regular script, with the character "Da" derived from "Tai". Among them, "Daxia" is the country name, and "Zhenxing" is the reign name. This is the first time in Chinese history that the country name and reign name are combined on coins, which has important historical significance."
"The diameter and weight of this coin are very consistent with the characteristics of a genuine Daxia Zhenxing. If you look at the text on the coin, the brushstrokes of this regular script are open and stretched, and it has the charm of early Six Dynasties calligraphy. Therefore, based on the rust color, shape, casting and calligraphy, we have no reason to say that this Daxia Zhenxing is a fake."
Old Liu looked at Yang Jing again and said with a smile: "Not to mention that this Daxia Zhenxing coin was taken out of the gold and silver sword brought by Xiao Yang. This sword has been buried underground for more than a hundred years. In the late Qing Dynasty and early Republic of China, there was probably no such high counterfeiting skills to make such a delicate counterfeit, right? Moreover, Daxia Zhenxing first appeared in the coin world in the late Qing Dynasty and early Republic of China. Fang Yaoyu's coin was first recorded in "Yaoyu Miscellaneous Goods" in 1925. If we infer from this, even if there was an imitation based on Ding Pu at that time, the imitation was less than a hundred years ago. In the past hundred years, it is difficult for such imitations to be buried in the ground and wait for people today to dig them out. Therefore, the authenticity of its patina and rust color is not difficult to identify. In a word, the patina and rust color buried in the ground for a thousand years is not something that can be easily imitated!"
Finally, Mr. Liu emphasized, "This Daxia Zhenxing is undoubtedly a genuine product!"
Although Mr. Liu is engaged in cultural heritage protection technology and his specialty is the protection and restoration of bronzes and ancient bronzes, his own level of identification is extremely high. Without his superb identification skills, he would not have become a research curator at the Palace Museum, let alone a leader in the restoration and protection of bronzes and ancient bronzes in China.
Now that he said it so confidently, the identity of this Da Xia Zhen Xing can be confirmed without a doubt.
The girl from Xiao Zheng turned her head and whispered to Yang Jing: "Is this Da Xia Zhen Xing yours?"
Yang Jing nodded and said, "I bought two golden swords from Panjiayuan today, but they were badly rusted, so I asked Old Liu to clean them up. As a result, I accidentally found a Great Xia Zhenxinglai."
The other Xiao Zhao asked: "How much did you pay for this sword?"
"One thousand dollars."
"Oh my god, you really got a great bargain! The real Da Xia Zhen Xing has appeared in auctions four times. Except for the one in 2011 that was sold for 1.01 million because its quality was really poor, the other three Da Xia Zhen Xing were sold for more than 150,000 yuan."
Xiao Zheng next to him said, "That's right. In 2004, the first Da Xia Zhen Xing appeared at the auction and was sold at a high price of 1.657 million. In addition, at the 2010 auction, a Da Xia Zhen Xing was sold at a high price of 2.02 million. The Da Xia Zhen Xing in 2014 was sold at a high price of 2.25 million! If you clean up your Da Xia Zhen Xing, it's in good condition. If you put it up for auction, it will definitely sell for 200!"
"What are you talking about there? Why are you saying nothing but useless things?" Old Liu suddenly shouted loudly. Xiao Zheng and Xiao Zhao immediately shrank their necks and heads like quails.
"You only think about those things all day long. These are the country's treasures. How can they be measured by money?" Old Liu scolded again.
Seeing that the situation was not good, Yang Jing quickly said in a conciliatory way: "Mr. Liu, please don't talk about them for now. Take a look at the remaining copper coins to see if there are other treasures. What if another Great Xia Zhenxing appears? If another Great Xia Zhenxing appears, I will give you one to keep for fun. How about that?"
Cai Yi said unhappily, "Stinky boy, where's mine?"
Yang Jing smiled and said, "We have them all. As long as there is Daxia Zhenxing among the remaining copper coins, you two elders can keep one for fun!"
Old Liu's mood turned from gloomy to bright, and he said with a smile: "Xiao Yang, you are quite magnanimous..."
As he spoke, Mr. Liu carefully picked up a black ancient bronze coin on the table, wiped it with a dry cloth, and began to brush it with a brush.
A few minutes later, Old Liu stopped what he was doing with a dazed look on his face. Cai Yi took a look and moved closer. However, after taking a quick glance, he found that the man was also stunned, as if he had seen something incredible.
Xiao Zheng and Xiao Zhao wanted to go over and take a look, but since they had just been scolded by Old Liu, they did not dare to go forward.
Yang Jing didn't care. He smiled and came closer to take a look. He immediately shouted in surprise: "Damn it! Don't tell me this is a Da Qi Tong Bao!"
After Yang Jing shouted, not only was Mr. Liu's office in chaos, but even the workshop outside was in chaos.
PS: I would like to thank “冰冷八度” for the reward of 100.
