"Yes, it is indeed traced." Chu Chen introduced: "There are many ways to trace slides. I will briefly mention two. One is to put the real thing underneath, with a layer of glass in the middle, and cover it with rice paper, and then The slide is illuminated from bottom to top, and the forger draws the gourd according to the yin and yang light and darkness illuminated. " Another method is to use a slide to print out the photos or pictures in the pictorial, project them on the rice paper, and then make them. The faker draws according to the picture. If it is a calligraphy work, he first outlines it with a pen and then fills it in with ink. With these two methods, as long as the imitation is in place, the fake one can look like the real thing. It¡¯s just fake, and there is some gap between it and the original. Like this calligraphy work, it lacks some charm compared to the original. If you put it next to the original, you can compare it.¡± After hearing Chu Chen¡¯s explanation, Qi Baofu. He sighed and said: "There are really endless ways to counterfeit antiques now. I think I should really recharge my batteries in the future." Chu Chen heard this and said: "Old Qi, your idea is very correct. In the world of collecting Although there are endless methods of counterfeiting, no matter how sophisticated they are, you can always find flaws and problems with careful observation and careful analysis. But this all presupposes that you have the corresponding knowledge and experience. "If someone had said this to Qi Baofu in the past, he would have heard it in one ear and out the other, but today he encountered two methods of forgery that he had never heard of before, which greatly shocked his heart. These words came from Chu Chen again, so he quickly expressed that he would keep them in mind. Next, Chu Chen appreciated the few remaining things. It was found that, without exception, they were all fakes, and they were all made using the latest scientific methods, so that they could be copied to a high level and look just like the real thing. Not to mention Qi Baofu, even some experienced old players might have had their eyes set on it. Hearing such a result, Qi Baofu didn't know what to say. How unlucky was he to encounter such a chance? This made him extremely depressed at the same time. I finally made up my mind to solidify my basic skills in antiques before continuing my collection. Seeing Qi Baofu's dejected look, Chu Chen could only shake his head secretly. In the final analysis, this matter was still Qi Baofu's problem. If he hadn't always learned his lesson and bought this and that, he wouldn't have spent so much money in vain. I hope he can really hear what he said just now. Thinking of this, Chu Chen simply used his powers to check all the collections in the room. For Fang Jinbo, these things that looked fake at first glance could help him learn some experience, but they were of little help to him. "Huh?" Just as the inspection was coming to an end. Chu Chen was stunned secretly, and then he said: "Old Qi, let me help you take a look at these things in the house." Qi Baofu opened his mouth. Chu Chen was about to say that he didn't have to worry about it, but he was still a little reluctant, so he thanked him: "Teacher Chu, please excuse me." Chu Chen waved his hand to express that you were not welcome, and then started to look at them one by one. Of course, he had already checked these things with his powers beforehand. Now it's just a show, so. The identification process seemed a bit fast, but Qi Baofu believed in Chu Chen now, and he knew what his things were, so he didn't find it strange. Slowly, Chu Chen walked up to the thing that surprised him just now, which was a pile of copper coins. After he rummaged through a few coins, he let out a light sigh. Hearing this, Qi Baofu was startled for a moment, then trotted over quickly, followed closely by Fang Jinbo. "Mr. Chu, did you find something?" Chu Chen carefully observed the things in his hands, and then smiled: "Old Qi, you are so lucky, you actually got a 'Xianfeng Chongbao' back." Baoquan is a fifty-year-old carving mother. "Ah! Is it really a carving mother?" Qi Baofu's face was full of surprise after hearing this. "This is still fake. If you don't believe me, check it out for yourself." Chu Chen smiled and handed the copper coin to Qi Baofu's hand. Diaomu, also known as ancestral money, does not really participate in circulation and exchange. It is just a money-shaped mold used in the process of sand casting. Our country was the first to use the mold casting method to cast money - first directly carve a mold on the masonry, then use materials such as copper and stone to make a mother mold, and then use the mother mold to cast a large number of sub-models to cast money. The Fan casting method was still used until the Song Dynasty. In the Northern Song Dynasty, the sand casting method of mother's money had completely replaced the Fan casting method. This method continued for nearly a thousand years until it was replaced by machine stamping method in the late Qing Dynasty. The process of making the carved mother-of-pearl is not simple. Every time you start to mint coins, the money bureau needs to first use pure and fine ivory to carve it into a money sample according to the style of the coin to be minted, and then it is approved by the competent department. Then skilled craftsmen in qualified coppersmith shops use fine copper (not pure copper, but matchingA money-shaped mold with a small square hole or a small round hole is carved from a reasonable copper alloy, which is called ancestral money or carved mother money. At that time, only skilled craftsmen could carve high-quality ancestral coins. There would be no sand hanging during the impression process, thus forming a smooth coin mold. The accurate carving mother must be approved by the Money Bureau before it can be used. The perforation known as the "Golden Mouth" must be completed by the Money Bureau craftsmen to make it a secondary mold for impression casting. The mother money shape . Then, a large amount of circulating currency is officially minted through the mother money impression. Because considering that several mold reductions will occur during the production process from the mother carving to the mother money and then to the circulation money, and the grinding and polishing process after casting will also lead to a reduction in size and weight, there will be a machining allowance for the carving mother. Its size is significantly larger than officially circulated currency. The entire currency casting process is a process of continuous weight loss. Because of this, the carved mother is quite precious. Moreover, at that time, the carved mothers were strictly controlled in the hands of relevant personnel of the Money Bureau, and rarely leaked out. In addition, coupled with the vigorous search by collectors in the past century, it is now difficult to discover new carved mothers, and most of the existing carved mothers Some are exported overseas, or donated to major museums. Naturally, the number of carving mothers remaining on the market is as rare as stars and phoenixes, and they have become the target of collectors and collectors. Of course, because of the rarity of copper coins, carved mothers can also be classified as "high or low". Just like Qi Baofu's "Xianfeng Heavy Treasure" carved mother with "Baoquan Dang Fifty" on its back, it has been hidden because of its special historical meaning and quantity. Popular among friends. In the early years of the Xianfeng period, because the world was in chaos and the Qing government was in extreme financial difficulty, it decided to mint large amounts of money. As a result, there were a large number of stolen coins on the market. Even if the Qing court ordered strict inspections, they were banned repeatedly. Then, due to poor circulation among the people, the amount of money that was sold as 100 to 50 yuan was not smooth. The depreciation was severe and the casting amount was reduced. Xianfeng coins have various formats and a small mintage. Therefore, their carved mother coins, mother coins and sample coins are all extremely rare. Many are collected by major museums, and some are spread abroad. According to incomplete statistics, mainland private individuals There are only three pieces in the collection so far, which shows how precious they are. Chu Chen didn't expect that Qi Baofu actually had such a good thing here. Moreover, the calligraphy of this carved mother-in-law was grand, the writing was full of official meaning, and the shape was more ordinary than fifty coins. The carving was exquisite, and it was well preserved. It was quite valuable. rare. Qi Baofu couldn't put it down and played with the carved mother-in-law. He looked happy and said that he didn't expect it. Needless to say, he was very happy in his heart. Chu Chen smiled and said: "Old Qi, you are so stupid. You even piled up such treasures here. If one day you sell them as scrap metal together with these coins, how will you regret it to death? " Qi Baofu chuckled and said with some embarrassment: "Actually, these copper coins were transferred to me by a friend with poor eyesight. I have always regarded them as ordinary copper coins. Who knew that there were even carved mothers? Mixing in. "Yuan E, the friend Qi Baofu mentioned also lives in this community. Like Qi Baofu, he is a lover of antiques, but he does not have the financial ability of Qi Baofu, and the person in charge of the family is still in charge of the economy. His wife, he could only secretly save some money to buy antiques. In fact, he doesn't have any bad habits, and his wife doesn't support him buying antiques, but his eyesight is as bad as Qi Baofu's, and he buys fakes every now and then. Like Qi Baofu, he doesn't listen to anything his family says. So his wife got angry and stipulated how much money he could buy in a month. If there was more, he would have to return it no matter what, and he couldn't use the next month's money to deduct it. And that¡¯s how these copper coins came into Qi Baofu¡¯s hands. After talking about the origin of the thing, Qi Baofu scratched his head and said with a smile: "I don't know what to say. I finally picked up a big leak, but I actually picked it up from a friend." Chu Chen said with a smile: "Good on you. What are you going to do? Give it back to him? " "Of course it's impossible!" Qi Baofu shook his head and said, "Brother, he sold me the eagle mother by mistake. It's not like I didn't pay. Money. Besides, given his character, he wouldn't accept it if I gave it back to him. Then he would definitely be choking on it, and it would definitely affect our friendship in the long run. It would be better to do this elsewhere. I'll make it up to him." Chu Chen agreed with Qi Baofu's words. Friendship is best not to be affected by money, otherwise it will turn sour sooner or later. That's why brothers have to settle accounts openly. Specifically, if Qi Baofu returns the money, he will feel unhappy, and if his friends don't accept it, he won't feel happy either, so it would be better not to say anything. Some friends may say that this is because Qi Baofu is not broad-minded enough. Since he is a friend, what is the problem if he returns the favor. That's right, but Qi Baofu is an ordinary person after all. How many ordinary people don't care about something worth hundreds of thousands? If you pay it back this time, you will encounter millions of people next time.Are you going to pay back the thing or not? Therefore, Qi Baofu would rather compensate his friend in other ways than let this matter become a barrier to the friendship between the two parties. (To be continued)
