Happy Tycoon

　　 Following the voice of Mr. Liu, he immediately started to act outside. After a while, a man and a woman walked in with their own things.

"Teacher, this is the tool you want." Two people respectfully placed the micrometer and a small and exquisite high-precision electronic scale on the workbench. Old Liu said casually: "Don't go, you two, wait a moment, I After identifying this ancient coin, you can hit it here."

　　 The two young men showed joyful expressions on their faces. The girl in her twenties asked: "Mr. Liu, what baby have you found again?"

Liu Lao said with a smile: "I just discovered a universe sword of medicine saint Li Shizhen, and now I have discovered a suspected genuine Daxia Zhenxing ancient spring. Xiao Zheng, let you see this kind of national treasure in a moment. "

　　 After finishing speaking, Liu Lao didn't bother to pay attention to these two disciples any more, but concentrated on operating the tools.

After a while, Lao Liu excitedly said, "It should be the genuine product! It is 23mm in diameter and 2.8g in weight. It is exactly the same diameter as the real one from Libo, and weighs slightly 0.6g, but this is not a problem. It was shot in 2004. The Daxia Zhenxing is more important than this one. The key is that this Daxia Zhenxing should belong to the same model as the Libo one!"

The two young men also came up and stood side by side with Yang Jing. Old Liu continued: "Look at this great summer. Its copper is reddish, and its body is rusty and old-fashioned. It is rusty. Armor, tightly wrapped around the body of money, rust is born from bones, and to discern money from rust, they are all time-honored things, not forgery in modern times. From the perspective of its casting, it is regular and dignified, and the face is well worn. Too", the real book contains the official rhyme. The writing and basic shapes have been unearthed before the typical characteristics of money."

　　 Yang Jing asked, "Lao Liu, can we tell that this copper coin is genuine from these aspects?"

Liu Lao said with a smile: "Of course there are more than that. Daxia Zhenxing money was made by Daxia Helian during the period of the Sixteen Kingdoms during the Daxia Zhenxing period, that is, 419-424 AD. During the Eastern Jin Dynasty, the Hun aristocrat He Lian Bobo was named "Xia" in Shaanxi Province in 407 AD, and was founded as "Zhenxing" after occupying Chang'an in 419. Da Xia Zhenxing money was probably made at this time, with a relic of reckless money in its shape and fine internal and external profile. The text'Da Xia Zhen Xing' is read in right-handed four-characters, which is a true script in half-li and half-kai, and the word'Da' starts from'太'. Among them,'Da Xia' is the national title, and'Zhenxing' is the reign title. It is the first time in Chinese history that the national title and reign title have been combined on coins, and it has important historical significance."

"The diameter and weight of this coin are very much in line with the characteristics of the authentic Daxia Zhenxing. Look at the Qian Wen. This kind of real calligraphy is open and stretched, and it has the charm of the early Six Dynasties. Therefore, from the rust color, The form, casting and calligraphy are combined to identify, we have no reason to say that this Daxia Zhenxing is a fake."

Lao Liu looked at Yang Jing again, and said with a smile: "Not to mention that this Great Xia Zhenxing Money was taken out of the money sword that Xiao Yang brought. This sword light is probably buried in the ground. It has been more than a hundred years. At the end of Qing Dynasty and the beginning of the Republic of China, I am afraid that there was not such a high level of craftsmanship to make such exquisite fakes, right? And the first spring world of Daxia Zhenxing should be in the late Qing Dynasty and the beginning of the Republic of China. This money was first recorded in the "Yong Yu and Miscellaneous Goods" in 1925. According to this inference, even if it was imitated on the basis of Ding Pu at the time, its imitations were less than a hundred years ago. In a century, such imitations are difficult to reproduce Enter the soil and wait for people to dig it out. Therefore, the authenticity of the patina is not difficult to distinguish. In a word, the patina of the patina is easy to imitate!"

　　 Finally, Liu Lao said in a more serious tone: "This Daxia is truly authentic!"

Although Lao Liu is engaged in cultural preservation and technology, his specialty is to protect and restore bronzes and bronze wares, but his own appraisal level is extremely high. If there is no expert appraisal skills, he will not become a researcher in the Palace Museum. Librarians are even less likely to be the leaders in the restoration and protection of bronzes and bronzes in China.

　　 Now that he said so surely, the identity of this Daxia Zhenxing can already be confirmed.

　　 The little Zheng's girl turned her head and asked Yang Jing in a low voice, "This Daxia Zhenxing belongs to you?"

Yang Jing nodded and said, "I bought two money swords from Panjiayuan today, but the rusty ones are quite bad, so I asked Mr. Liu to clean them up, but I accidentally cleaned one out. Great Xia is really coming."

　　 The other Xiao Zhao said, "How much did you buy this sword?"

　　 "One thousand yuan."

"My God, you are really picking up this leak! Now Da Xia Zhenxing genuine product has appeared in auction four times, except for the one in 2011 that was sold for 1.01 million because of its poor quality. In addition, the other three Daxia Zhenxing pieces were sold at prices above one hundred and five."

Xiao Zheng next to him said: "Yes, Da Xia Zhenxing first appeared at the auction in 2004, and directly sold a high price of 1.65 million. In addition, at the 2010 auction, a large Xia Zhenxing sold a high price of 2.02 million, and the 2014 Daxia Zhenxing was sold at a high price of 2.25 million! If your Daxia Zhenxing is cleared out, it will look good. If it is sold, Two hundred is appropriate!"

　　 "What are you talking about there? How can you say something useless?" Old Liu suddenly scolded loudly~www.readwn.com~ Xiao Zheng and Xiao Zhao suddenly shrank their necks and heads like quail.

　　 "I know all the time that I'm thinking about those dumb things, these are the treasures of the country, how can they be measured by money?" Liu Lao scolded again.

Yang Jing saw that the formation was not good, and hurriedly said, "Lao Liu, don't talk about them for now. See if there are other treasures in the remaining copper coins? What if there is another big summer? What about Zhenxing? If there is another big Xia Zhenxing, I will give you one to play with, kid?",

　　 Cai Yi said angrily: "Smelly boy, where's mine?"

　　 Yang Jing smiled and said: "Both, both, as long as there is Daxia Zhenxing in the remaining copper coins, you two and the old one will hide and play!"

　　Lao Liu is now overcast, and smiles: "You Xiao Yang, you are very angry..."

　　 Talking, Liu Lao carefully picked up a black bronze coin on the counter, wiped it with a dry cloth, and then started to brush it up with a brush.

A few minutes later, Liu Lao stopped the movement in his hand with a dull look. Cai Yi glanced at it and moved closer. After a glance, the master was also stunned, as if he saw something incredible. Things are so-so.

　　 Xiao Zheng and Xiao Zhao wanted to come over and take a look, but they were scolded by Liu Lao just now, and they did not dare to step forward.

　　 Yang Jing didn’t care, he smiled and looked at it, and immediately shouted in surprise: "Damn! Don’t say that this is a big Qi Tongbao!"

　　 After Yang Jing shouted out with this voice, not only was Lao Liu's office messed up, but even the outside workroom was messed up.

　　PS: Bow to thank the "Icy Octave" 100 for the reward.
