In recent years, the ancient coin market has been flooded with counterfeits, and there are many kinds of pseudo-techniques. Especially the popularization and application of modern high-tech, the fidelity of the products is higher, so people's ability to discriminate is also improved. The identification of coins is not something that can be learned overnight. We need to get regular contact with genuine and fake products. We can start from the aspects of material, text, color, weight and smell of coins, and accumulate experience for a long time.
First, the text production identification: recognition of text production is the most critical one. First of all, we must examine its overall production style from a macro perspective, whether it conforms to the atmosphere of the times, whether it conforms to regional characteristics, and whether it conforms to the personality characteristics that this coin should have.
The money on Chinese ancient money is not only the symbol of the coin, but also the most concentrated part of the art of coinage. Because the currency officially circulated in ancient China generally has no pattern, the main modification of ancient money is the text.
At the same time, Qian Wen is also an important part of ancient money security. Although Qianqian ancient money, Qian Wen is out of the hands of the craftsman, but the pre-Qin script is profoundly difficult to understand, and the pseudo-persons often make mistakes because they do not understand the ancient scripts; the Qian Wen after the Qin and Han dynasties are more from the hands of calligraphy, which is not only beneficial to improve The artistic level of ancient money, and each book has its own characteristics, is the most effective personality. If others are copying, it is difficult to achieve perfection.
Mastering the character of the ancient money, you can make a decision quickly. If you look at it at any glance, no matter from which angle, it is reasonable, in line with its commonality and personality characteristics, then, of course, is the real thing, that is, the so-called "open the door" in the coin world, some places are called "one eye"; the other is the fake, Can also be determined. Here, we should pay special attention to the fake money directly cast by real money. Because of this kind of forgery, the writing is not easy to find flaws. However, after a sanding, its delicate degree, there is always a reduction in color, it seems that the spirit is insufficient, especially because of the cause of thermal expansion and contraction, the new fake money will be slightly smaller than the original money.
Second, the color discrimination: the ancient money before the Tang and Song Dynasties, due to the age, the general rust is serious, no matter the hard green rust, or the soil rust, are rust colored into the bone, and even the body is rust, the rust knot and the money body bite together It is difficult to strip. False rust is only floating on the surface of the money and is easy to peel off.
Some people use acid soak vinegar to soak, or boil in boiling water, even with acupuncture, sharpening with a sharp tool, these are of course a way to test false rust, but the use must be careful and cautious, it is best not to take such chemistry Or physical means. Because, if it is a famous treasure, after such treatment, the fine rust will be destroyed and irreparable. In fact, the rust is naturally natural, giving people a pleasing enjoyment; fake rust is always a place of artificial work, giving people an unpleasant feeling.
In the identification of color and color, special attention should be paid to the identification of real money pseudo rust and fake money. The so-called real money pseudo rust means that for some special reason, the real money is in a fire. The appearance of the fire is extremely embarrassing, or when it encounters chemicals such as acid, it is rusted and rusted, and it is accompanied by an embarrassing " The new "rust" gives a false feeling. For this kind of situation, it is not easy to negate only the rust color. The key is to look at the text production and do a comprehensive analysis before deciding. The so-called fake money is really rust, it is to remove the old rust on the ordinary real money, stick to the fake money, to fake the truth, for this situation, you can not easily rely on rust color.
Third, the weight of the phonetic rhyme: the ancient money, whether it is unearthed, or handed down the world, are old, the fire has been off, unlike the new money. Especially the money with serious rust, the actual weight has been greatly reduced, so experienced people, an ancient money in the hand, there will be a special feel. Then gently put the ancient money on the table, the surface seems to be a natural movement, actually listening to the sound of its contact with the desktop.
The sound of ancient money is loud and there will be no sound, and the new fake money will make a crisp turn. In order to avoid the transfer of new money, the fake veteran will put the new money on the fire, burn it, put it on the table, the voice is dumb, or intentionally destroy the money, break the corner, so that The rupture, the broken money, will only make a dumb sound, and give people an old illusion. Therefore, for the money burned by the fire and the cracked money, pay special attention to the identification. In addition, for the money that is rewritten, because the money itself is true, it cannot be judged by the feel or the phonology alone.
Fourth, the smell is discerning: The newly unearthed ancient money has a kind of earthy smell, and people who often come into contact with ancient money and cultural relics will have a kind feeling. Counterfeit fake money often has some unpleasant smell, and fake rust pasteed with rosin, glue, epoxy resin, etc., will also have different odors.
The various methods of discriminating are not absolute or isolated, but intertwined and complement each other. When identifying ancient money, it must be comprehensively applied and comprehensively analyzed. It is necessary to do subtle research on the micro level, and to conduct a comprehensive investigation from a macro perspective. For the identification of every kind of ancient money, it should be based on money and targeted, in order to grasp the key points and find a breakthrough.
