The man was hurt first and then happy, thanked Gu Yuping repeatedly, and then went down happily after getting the appraisal certificate. Qin Banliang's clarification set off the atmosphere. The person who came to the stage was full of confidence. Luo Tian glanced at it and it turned out that it was
Knife coin!
Knife is a copper coin name in ancient China. It evolved from a knife that produces tools. It was circulated in Qi, Yan, Zhao and other countries during the Spring and Autumn Period and the Warring States Period. There are many types, including Qi Dao, Jimo Dao, Anyang Dao, and Needle-Shou Dao.
, pointed-headed sword, round-headed sword and Ming sword. There are words on it. After Qin Shihuang unified China, he unified the currency system, scrap shells, knives, cloth and other coins. Later, there were gold-faulted swords among the coins minted by Wang Mang.
The biggest feature is that it looks like a knife, so it is named "Kao Coin". It consists of four parts: the head of the knife, the body of the knife, the handle of the knife and the ring of the knife. The edge of the knife is contoured by the outer contour, the blade does not face outward, to the left but not to the right.
The concave and convex blade is close to a three-picture shape, the blade body and the handle are two rectangles of similar size, and the knife ring is circular. These geometric shapes are cleverly combined to form a stable, circumferential and plump
, the round image is beautiful and harmonious. According to actual measurement, the diameter of the knife ring and the length of the knife head are 1:7.5, which is exactly the ratio of the head to the height of a person.
Does this ratio mean that the process of making this knife coins takes into account the human body structure? The wisdom of the ancients was so profound that it was elusive that Luo Tian suddenly thought of this point.
The knife coins that the man took were rounded and the head of the knife, the handle and the blade were close to perpendicular, and the front of the knife contained the words "Handan". "Handan was the ancient capital of Zhao during the Warring States Period." Luo Tian immediately said it
.
Gu Yuping laughed: "That's right. If Zhao Guodao coins, then the size of this sword coin should be about 13 to 14 cm and weigh about 5 to 15 grams. The shape of Zhao Guodao coins is relatively small, the smallest
It's the Yanyang sword you brought."
Yan Yang Dao? Luo Tian was almost jumping up. This is an extremely rare and rare ancient coin. Some say that Yan Yang is also Jinyang, but only 9.5 cm, very small, similar to Lin Dao, for Yan Yang Dao
Although the study of the age of coins is still controversial, most of them believe that it belongs to Zhao Guodao coins.
As soon as Yan Yangdao's conclusion came out, there was a lot of discussion on the spot, and even Huang Lide became interested: "Let me see."
Huang Lide looked down and immediately smiled: "Good eyesight, it's really Yan Yang Dao!!"
Luo Tian also looked at it with the flow. The age showed that it was indeed Zhao State. This ancient jade Ping was still very skilled. He smiled muffled. The ancient jade Ping's sensitivity to ancient coins was no less than that of himself. Luo Tian suddenly had a strange feeling.
I thought that if I had no superpowers, Gu Yuping's ability in ancient coins might be completely beyond him.
The appearance of Yan Yang's sword suddenly killed Qin Banliang. The Doubaoren who was in the game was so excited that he couldn't do it himself, so he jumped up on the spot: "That's great!!"
Huang Lide reminded him: "Don't panic, you are just taking the lead for the time being. If you want to win the final victory, your destiny is still in the hands of the people below." After saying this, the competitions that had not yet come on stage were clapping.
, It’s not certain who can laugh to the end!
The coins that came up made Yan Yangdao's master burst into cold sweat, just because it was the real "Jingkang Tongbao"!! Jingkang Yuanbao was minted during the reign of Emperor Qinzong of the Northern Song Dynasty. He was captured to the north after 16 months of reign.
. Therefore, the amount of money cast in "Jingkang" is very small, and "Jingkang Tongbao" is even more rare, and it is a national first-class cultural relic!
It is expensive if you are too small. For example, the Nankang "Daqi Tongbao" that only found one piece so far, and the "National Treasure Jinkui Zhi Wan coins" in the Western Han Dynasty, are all called "solute products" among coins, with extremely high collection and
Investment value: The Jingkang Tongbao that the man brought was made of copper, and the calligraphy was written in seal script, with a diameter of 31.5 mm and a weight of 7 grams. In short, it is a treasure.
The Xinyang sword hit Jingkang Tongbao, which is undoubtedly due to Mars hitting the Earth. It is hard to say which one wins. The value competition of antiques is a wonderful thing.
The owners of these two ancient coins were a little bit gunpowder. Luo Tian sighed and said, "There is only one first. You cannot lay two yolk eggs in this kind of treasure battle competition, otherwise it will violate the principle of fairness and justice."
The competition for ancient coins was exciting. There was no fake that was presented next, but they were all coins from the Qing Dynasty, and they were all mechanical coins.
During the Guangxu period of the Qing Dynasty, Zhang Zhidong, the Governor of Guangdong and Guangxi, absorbed the advanced technology of Western coins, purchased coin making machines from the UK, and prepared to build a mint in Guangzhou. He took the lead in creating machine-made coins and implemented the third revolution in the history of Chinese coins. Advanced.
The currency-making technology was successful in the late Guangxu period. After that, all the coins in the Qing Dynasty were mechanisms. There were many such mechanisms, and many of them were passed down. Naturally, they were discounted in value and could not be matched with Xinyang Dao and Jingkang.
Ancient coins like Tongbao are compared.
Luo Tian always felt that there was something missing in today's competition. Yes, ancient coins cannot be just ancient coins, but ancient coins must also be ancient coins! That is, paper money!
Gu Yuping also discovered this and whispered: "Following the information, the people who signed up came with paper money."
While speaking, the person who came up was holding a banknote in his hand. Luo Tian took the opportunity to say, "Teacher Gu's mouth is so smart." At the same time, he also smiled and smiled.
Gu Yuping knew that Luo Tian was teasing him, but he couldn't get involved with Luo Tian in this occasion. He could only groan and temporarily look at the ancient banknote in front of him!!
In Chinese history, only the Yuan and Ming dynasties were popular in paper money. The Yuan Dynasty mainly used banknotes. According to legend, after the founding of the Yuan Dynasty, Kublai Khan, founded the capital of Shangdu, he wanted to imitate the Song Dynasty with copper coins as the main circulating currency, but some ministers persuaded him.
"Copper coins are used by the Yangming regime in China. We originated from the northern grassland area and belong to the dark place. We cannot compare with the Yangming area in China. Paper money is applicable to our country." Kublai Khan thought it was reasonable, so he decided to use paper
Don’t use copper coins.
Later, Zhu Yuanzhang, the first emperor of the Ming Dynasty, followed the successful issuance of paper money by the ruler of the Yuan Dynasty, and also issued paper money by the Ming Dynasty after the founding of the country.
The circulation of paper money in the Yuan Dynasty mainly experienced three periods: Zhongtong Notes, Zhiyuan Notes and Zhizheng Notes. Among these three periods, the Zhongtong Notes had the most stable currency value, and the Zhiyuan Notes had the longest circulation time. It exceeded 36 before and after.
Year.
Now in front of the ancient jade plane is a Zhongtong Yuanbao Jiaobao Jiaobao. "Zhongtong Yuanbao Jiaobao" is the earliest existing banknotes in China that were officially officially printed and issued by the official (there are no physical objects in the Song Dynasty banknotes so far). The engraving and printing time was in the Yuan Dynasty.
During the Kublai Khan era in the first year of Zhongtong (1260 AD), this kind of banknote is no different from modern banknotes.
But it still needs to be distinguished from the authenticity of this banknote. Gu Yufang glanced at Luo Tian and asked Huang Lide: "Teacher Huang, I can tell that the authenticity of this banknote is true and false, let Luo Tian take a look!!"
Oh, this is a difficult thing for myself. Luo Tian pursed his lips tightly, but there was a smile on his lips. Who is afraid of who!
