Tang Feng understood that the value of ancient coins is first related to the material, iron coins, copper coins, silver coins, jade coins, gold coins, and prices are going all the way. The value of coins minted by precious metals is definitely high, and the price of selling scrap iron is different.

Secondly, it is related to the issuance volume. The less valuable the metal, the smaller the face value of the coins, and the smaller the face value. In order to ensure circulation, the issuance volume will increase. If the issuance volume is large, the remaining amount will definitely be more. If things are rare, they will not be valuable.

The third is related to the country and age of issuance. The land area is small, the circulation range will definitely be smaller. The shorter the issuance time and the smaller the issuance base, the higher its value will be. These three are proved by each other. If you refer to the existing volume, you can basically determine the value of an ancient coin.

Nowadays, each of the five thousand yuan worth nearly 200,000 yuan is a good example. Five or six of them were issued by the Wu Kingdom during the Three Kingdoms period, which were millionaires.

Tang Feng picked up a copper coin and put it in his hand and looked at it. The front of the copper coin was printed with the four words "Dashun Tongbao in traditional Chinese" and the reverse side was not written. It was a coincidence that the Dashun Tongbao in the above two periods had regular characters and could not confirm the age from the reverse side.

When the vendor heard the three words Zhang Xianzhong, he immediately said, "How could this be the Dashun Tongbao issued by Zhang Xianzhong? It was definitely the Dashun Tongbao issued by Li Ye of the Tang Dynasty."

In ancient times, people did not pay attention to the reign title, which caused modern people to argue. Zhang Xianzhong's Dashun Tongbao was issued during the Peasant Uprising in the late Ming Dynasty. Its volume was not large, but it could be worth dozens of yuan. However, in 890 AD, Emperor Zhaozong of Tang Dynasty, Li Ye, changed the reign title to Dashun, and the Dashun Tongbao issued at that time was even more valuable. This was not only because the princes were in power 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. It was also because the reign title of the Dashun of the Tang Dynasty only lasted for two years and the reign volume was very small, so the value reached six or seven hundred.

They are all square cave money and Dashun Tongbao, but the value gap is quite large. No wonder vendors are serious about this era.

Tang Feng changed several big shun Tongbao in a row and weighed it in his hand. Finally, he chose one. He said, "It is indeed the big shun Tongbao of the Tang Dynasty." He pointed to the square hole above and said, "This hole is smaller, Zhang Xianzhong is smaller, and Li Ye is bigger."

"Haha!" A burst of laughter came from behind Tang Feng. What is the size of this saying?

Tang Feng had no time to joke, and he asked, "Boss, how much does it cost?"

Seeing Tang Feng's outfit, the vendor didn't treat him as a target customer at all, and said casually: "800 per coupon, no bargaining."

"I'll want this one." Tang Feng did not bargain, but put the copper coin in his pocket, then took out the stack of money and counted more than twenty pieces for the vendor. It was not to give the tip, but the money was too broken.

The vendor was a bit outrageous. Unexpectedly, the old hat didn't even pay the price. He immediately asked with a smile on his face: "I have ten of them here in total, you just want one?" As long as you have money, the old hat is the master!

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

"Young man." The old man said earnestly: "Your handwriting is already blurred, and your appearance is the worst among the ten. I think you should look carefully and change one?"

"Thank you for your always reminder." Tang Fengbao smiled and said, "What you want is this quaintness."

Tang Feng said nothing and left quickly. The old man said to the vendor: "There are nine more, can you offer a price?"

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

The old man whispered to the vendor: "Everyone is from the industry, and the wise man doesn't say secret words. The remaining nine pieces and 1,000 left together. How about it?"

"What are you kidding? That won't work!" The vendor immediately shook his head.

The old man said in the vendor's ear: "Do you think that making the square hole bigger, then immersing it in vinegar with copper sulfate, and finally burying it in the soil can deceive people? I'm looking at the price you paid for in the ancient times, one hundred yuan per piece, you're already making enough money."

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 is 1,500. If it doesn't work, it's just not possible." After the old man finished speaking, he got up and left.

He had just taken a few steps and the vendor shouted, "Oh, I'm going to give you a loss, just follow the price you said!"

When everyone saw this situation, they understood that the countryman was deceived.

Any shop selling antiques will also buy antiques, buying low and selling high. The rare goods are common business roads in ancient and modern times. Tang Feng walked into a small shop on the other side of the street. The boss looked up at him and ignored him.

Tang Feng said: "Boss, do you collect ancient coins?"

"You have?" The boss was energetic. Such people from other places had no money at first glance. Don't expect him to buy things, but if he came to sell things, the situation would be very different. Such people don't know what they know and lack money. They often have the opportunity to buy good goods at low prices.

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

"Tianshun Tongbao? Really?" The boss stood up immediately.

The boss took the copper coin, took the magnifying glass and looked at it again and again. After that, he sat in front of the computer, moved the mouse to call out the picture, and compared it carefully with the real object. Finally, 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 easily: "If you really don't know the goods, I can go to another house, but if you want to bully me, you're a big mistake. If you don't know what to do, I dare to enter this school? Although the horizontal line of the word "Tian" has been corroded with the money edge, and is so blurred that it can't be seen clearly, the pen tip is slightly blunt, which is definitely not a natural corrosion effect."

As soon as an expert said that, he knew if there was anything. After hearing Tang Feng's words, a hint of hesitation flashed across his face. Tang Feng said, "All people in the industry, you might as well open the skylight and say something bright."

The boss smiled slightly, nodded and said, "Master, you are indeed a master. You picked it out of a bunch of big Shun Tongbao, right?" The businessman's mind was so empty that he could not hide others, so let's be real.

Tang Feng shrugged and said, "There is nothing to tell me about. Do you want it?"

"You can offer a price." said the boss.

"This number." Tang Feng stretched out two fingers, and then he said: "The boss is not unaware of the recent market. You can make two thousand yuan by just one hand, which is already a lot."

Tang Feng did not say the numbers directly, but the boss did not ask him in detail. He shook his head and said, "This Tianshun Tongbao is seriously corroded. It is a bit expensive for 20,000 yuan, up to 15,000 yuan."

Those who rely on cultural relics to make a living are experts. If it weren't for the serious corrosion, how could this Tianshun Tongbao fall into Tang Feng's hands? Fortunately, the street vendor who was slashing his eyes saw that the square hole of this "Dashun Tongbao" had naturally corroded and expanded, and did not add to the snake and then "processed", otherwise the Tianshun Tongbao would be useless.

Tang Feng thought for a while and said, "Although there is some corrosion, the main body is still complete. As long as you do a little repair, the quality will definitely not be much different, 19,000."

The boss said: "Repairing is time-consuming and labor-intensive, not an easy job, 16,000."

Tang Feng said: "Get a prize for a prize, 18,000 yuan, if I don't have it, I'll change to another family!"

"Transaction!" The psychological prices of both parties were getting closer. The boss finally got ready. He took out two stacks of red RMB with seals from the safe below. After drawing 20 pieces, he handed the money to Tang Feng and said, "If you have something in the future, you can get it again and again. As long as everyone has earned money, you can guarantee that the payment will be paid."

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

There are exceptions in everything. The orthodox, Jingtai and Tianshun of the Ming Dynasty showed the unique phenomenon of three dynasties and two emperors in history. The emperor of the Ming Dynasty in the Zhengtong year was Zhu Qizhen, the Ming Yingzong. Zhu Qizhen personally led the Northern Mongolian campaign in the 14th year of Zhengtong, but was defeated and captured. This is the famous Tumu Fort Incident in history.

Later, Ming Dynasty Emperor Zhu Qiyu ascended the throne and changed the yen name to Jingtai. This matter was originally over, but the Mongols released Zhu Qizhen back. Zhu Qiyu did not handle the "aftermath" well, and as a result, raising a tiger became a disaster. In the seventh year of Jingtai, Zhu Qizhen used a quilt to kill Zhu Qiyu who was seriously ill, and became the emperor himself and changed the yen name to Tianshun.

Weird people create strange times, and strange things happen in strange times. Therefore, the three dynasties, Zheng, Jingtai, and Tianshun also had strange pieces of official porcelain passed down. Similarly, the number of Tianshun Tongbao in the Tianshun period was very small, and it is not surprising that each Tianshun Tongbao is worth up to 22,000 yuan.

All merchants are not traitors. The vendors turned the Dashun Tongbao, worth dozens of yuan in the late Ming Dynasty, into the Dashun Tongbao, worth hundreds of yuan in the late Tang Dynasty, but he never dreamed that there was a Tianshun Tongbao from the Ming Dynasty mixed in this pile of Dashun Tongbao.

He thought he had made a lot of money by selling it to Tang Feng for 800 yuan. While he was laughing secretly, Tang Feng was also laughing secretly. This is the way of saying one foot higher than the devil, and there are still traitors among the traitors!

As soon as Tang Feng walked out of the store, he met someone who was really for Tang Feng.
