Tang Feng understands that the value of ancient coins is first related to the material, iron coins, copper coins, silver coins, jade coins, gold coins, the price goes all the way, the value of coins minted by precious metals must be high, and the price of selling scrap iron is not the same.

Secondly, it is related to the circulation, the less valuable the metal minted by the coin, the smaller the face value, the smaller the face value, in order to ensure circulation, the circulation will increase, the circulation is large, the survival of the world must be more, the scarcity is expensive, then it is not valuable.

Third, it is related to the country and era of issuance, the small land area, the circulation range must be small, the shorter the issuance time, the smaller the issuance base, the higher its value. These three corroborate each other, and with reference to the surviving amount, the value of an ancient coin can basically be determined.

Today, Daquan 5,000, each worth nearly 200,000 is a good example, and five or six of the pieces issued by Wu during the Three Kingdoms period were millionaires.

Tang Feng picked up a copper coin and put it in his hand to look at it, the front of this copper coin is printed with the traditional Dashun Tongbao four words, the reverse side is not written, it is also a coincidence, the above two periods of Dashun Tongbao have a straight word light back paragraph, can not confirm the age from the back.

As soon as the vendor heard Zhang Xianzhong's three words, he immediately said: "How can this be the Dashun Tongbao issued by Zhang Xianzhong? It is definitely the Dashun Tongbao issued by Li Ye in the Tang Dynasty." ”

The ancients did not pay attention to the name of the year, so that modern people pulled the skin, Zhang Xianzhong's Dashun Tongbao was issued in the late Ming Dynasty during the peasant uprising, and there were not many surviving amounts, but it could also be worth dozens of yuan. But in 890 A.D., Tang Zhaozong Li Ye changed the name of the year to Dashun, and the Dashun Tongbao issued at that time was more valuable, not only because the princes were divided at that time, and the copper coins issued by the central government could not be circulated in the local area, resulting in a decrease in circulation. Also because the Tang Dynasty's Dashun era only lasted for two years, and the circulation was very small, so the value reached six or seven hundred.

They are all square hole money, and they are all Dashun Tongbao, but the difference in value is not small, no wonder the vendors are more serious about this era.

Tang Feng changed a few Dashun Tongbao in his hand, and finally selected one, he said: "It is indeed the Dashun Tongbao of the Tang Dynasty." He pointed to the square hole above and said, "This hole, Zhang Xianzhong is a little smaller, and Li Ye is a little bigger." ”

"Haha!" There was a burst of laughter behind Tang Feng, what he said was bigger than something.

Tang Feng didn't have time to laugh, he asked, "Boss, how much is this?"

Looking at Tang Feng's dress, the vendor didn't regard him as a target customer at all, and said casually: "800 a piece, no counteroffer." ”

"Deal, I want this one. Tang Feng didn't bargain, he directly put the copper coin in his pocket, and then took out the stack of coins and counted more than 20 pieces to the vendors, not to tip, but the money was too broken.

The price of the vendor was a little outrageous, but he didn't expect this old hat to not even return the price, he immediately asked with a smile on his face: "I have a total of ten here, do you want one?"

Tang Feng nodded and said, "Well, I want this one." ”

"Young man. The old man said earnestly: "Your handwriting has been blurred, and the quality is the worst among the ten, I think you should read it carefully and change it, right?"

"Thank you for the old reminder. Tang Feng reciprocated with a smile and said, "What I want is this quaint." ”

Tang Feng didn't say much, and quickly left, and the old man said to the vendor: "There are nine more, can you make a price?"

The vendor said, "You have also seen it, 800 yuan a piece, a total of 7,200 yuan." ”

The old man whispered to the vendor: "Everyone is in the industry, the Ming people don't say secret words, how about the remaining nine 1000 together?"

"What are you kidding, that's not going to work!" the vendor shook his head immediately.

The old man whispered in the vendor's ear: "Do you think you can deceive people by making the square hole bigger, then dipping it in vinegar with copper sulfate, and finally burying it in the ground? ”

The vendor looked at the old man's expression and whispered, "How about 5000?"

The old man also lowered his voice and said, "The last price, 1500, if it doesn't work, it's only no." After the old man finished speaking, he got up and left.

He had only taken a few steps when the vendor shouted, "Oh, I've given you a loss, just at the price you said!"

When everyone saw this, they understood that the countryman had been deceived.

But all shops that sell antiques will also buy antiques, buy low and sell high, strange goods can live is a common business road in ancient and modern times, Tang Feng walked into a small shop on the other end of the street, the boss raised his eyes to look at him, ignored him.

Tang Feng said, "Boss, do you accept ancient coins?"

"Do you have it?" the boss came to the spirit, this kind of outsider has no money at a glance, you don't expect him to buy things, but if he is here to sell things, the situation is very different, this kind of person does not know how to do and lacks money, often take advantage of the opportunity, buy good goods at a low price.

Tang Feng took out the copper coin and said, "Tianshun Tongbao, do you want it?"

"Tianshun Tongbao, really?" the boss immediately stood up.

The boss took the copper coin, looked at it again and again with a magnifying glass, and then sat down in front of the computer, moved the mouse to call up the picture, and carefully compared it with the real thing. In the end, he returned the copper coin to Tang Feng and said: "This is the Dashun Tongbao at the end of the Tang Dynasty, not the Tianshun Tongbao." ”

Tang Feng said lightly: "If you really don't know the goods, I can go to another house, but it would be a big mistake to bully me for not knowing how to do it, do I dare to enter this door if I don't know how to do it? ”

As soon as the connoisseur exited, he knew if there was one, and after listening to Tang Feng's words, a trace of hesitation flashed on his face, and Tang Feng said: "They are all people in the industry, you might as well open the skylight and say something." ”

The boss smiled slightly, nodded and said, "Master, sure enough, you are a master, you picked it out from a pile of Dashun Tongbao, right?"

Tang Feng shrugged his shoulders and said, "I don't have anything to say about this, do you want it?"

"You make an offer. The boss said.

"This number. Tang Feng stretched out two fingers, and then he said: "The boss won't know the recent market, and he will earn two thousand when he changes his hand, which is already a lot." ”

Tang Feng didn't say the number directly, but the boss didn't ask him in detail, he shook his head and said, "This Tianshun Tongbao is seriously corroded, 20,000 yuan is a little more expensive, at most 15,000." ”

Those who rely on cultural relics to eat are experts, if it is not for serious corrosion, how could this Tianshun Tongbao fall into the hands of Tang Feng. Fortunately, the eye-catching vendor saw that the square hole of this "Dashun Tongbao" had naturally corroded and expanded, and there was no snake to add to the "processing", otherwise this Tianshun Tongbao would be scrapped.

Tang Feng thought for a while and said: "Although it is corroded, the main body is still intact, as long as it is repaired a little, the condition is definitely not much worse, ten thousand nineteen." ”

The boss said: "Repairing is time-consuming and laborious, and it is not an easy job, sixteen thousand." ”

Tang Feng said: "Ask for a lottery, 18,000, if you don't have it, I'll change to another family!"

"Deal!" The psychological price of the two sides is constantly approaching, the boss is finally refreshed, he directly took out two stacks of red RMB with seals from the safe below, and after drawing out 20 sheets, he handed the money to Tang Feng, and said: "If there are things in the future, even if you take them, once they are raw and twice cooked, as long as everyone earns them, the payment for the goods is guaranteed." ”

"No problem. Tang Feng took the money and counted it carefully, and after making sure that there were enough counterfeit coins, he put it in his backpack.

There are exceptions to everything, and the orthodoxy, Jingtai, and Tianshun of the Ming Dynasty have a unique phenomenon of three dynasties and two emperors in history. The emperor of the orthodox year of the Ming Dynasty was Zhu Qizhen of Yingzong of the Ming Dynasty, Zhu Qizhen drove the imperial expedition to Northern Mongolia in the fourteenth year of orthodoxy, and was captured in a fiasco, which is the famous Tumubao change in history.

After that, Zhu Qiyu of the Ming Dynasty ascended the throne and changed the name of the year to Jingtai, which was originally over, but the Mongols released Zhu Qizhen back. And Zhu Qiyu did not deal with the "aftermath", as a result, the tiger was raised, Jingtai seven years, Zhu Qizhen used a quilt to cover Zhu Qiyu who was seriously ill, and he became the emperor again, and changed the year name to Tianshun.

Strange people create strange times, and strange things happen in strange times. Therefore, the three dynasties of Orthodoxy, Jingtai and Tianshun also strangely did not have a single official porcelain handed down. Similarly, the number of Tianshun Tongbao in the Tianshun period is also very small, and it is not surprising that the value of each Tianshun Tongbao is as high as 22,000 yuan.

No businessman or treacherous, the vendor changed the Dashun Tongbao worth dozens of yuan into the Dashun Tongbao of the late Tang Dynasty worth hundreds of yuan, but he never dreamed that this pile of Dashun Tongbao was also mixed with a Tianshun Tongbao of the Ming Dynasty.

He thought that he would make a lot of money by selling it to Tang Feng for 800 yuan, and while he was snickering, Tang Feng was also snickering. This is the Tao is one foot high, the devil is one foot high, and there are traitors among traitors!

As soon as Tang Feng walked out of the store, he met a person head-on, and this person was really coming for Tang Feng.

Tang Feng smiled and said, "Yo, it's such a coincidence?" ”
