at present, the collection industry is slowly warming up, and sudden profits have gradually pushed the collection industry to its peak. With the rise of the RMB collection market, there are more and more counterfeits. In addition to checking their appearance, it is more important for collectors to study whether they are genuine or not. Try to avoid buying the expensive old version of RMB at the stalls on or without regular shops, because once there is an error, it will be difficult to investigate afterwards. In particular, some sellers whose products are brand new but whose prices are seriously lower than the market prices can hardly be considered by collectors. Don't be greedy for a temporary bargain and cause your own property losses. At the same time, you can find fakes

If the collection is not properly cared for, the old RMB collections may be degraded or even damaged. In order to ensure the integrity of RMB banknotes during the collection process, we must pay attention to five precautions:

1. prevent mildew. The key to prevent mildew is moisture resistance, which is particularly important in the South and coastal areas, and the key to moisture resistance is the temperature and humidity of the paper money storage. According to the analysis of relevant experts, the best indoor temperature for the storage of banknotes is 18-20 C, and the best humidity is 50-60%. Therefore, when cleaning paper money, try not to do it in a high temperature or humid environment. In the rainy season in summer, it is best to put the banknote books on the table at intervals and blow them with a hair dryer for a while, so as to dehumidify and prevent mildew. Generally speaking, old banknotes are more likely to become moldy than new banknotes. Once moldy, they can be gently wiped with soft paper or cloth. For seriously moldy banknotes, they can be soaked in fresh milk, added with a small amount of salt, taken out after an hour, rinsed with clean water, and then sucked dry with absorbent paper. When slightly damp, the banknotes are placed flat and clamped in a blank book, and pressed with heavy objects to dry naturally in the shade

2. anti folding. When storing or appreciating brand-new banknotes, it is best to use tweezers. Do not touch, twist or hold them directly, because there is oil sweat on your hands, which is easy to pollute the face. It is best to put the banknotes in a special transparent film bag and then put them into the coin collection book. For the paper money with slight soft fold, put it in the book smoothly, press the heavy object, and it will be leveled in a few days. For banknotes with obvious hard folds, the face is generally dirty. You can put them in water for 10 to 20 minutes, then take them out and put them between two absorbent papers and press them with glass. After drying, the wrinkles will be removed. The paper money printed with thin cotton paper should not be washed, because it is easy to damage the face and make it blurred. For uneven banknotes, do not use an electric iron to ensure the durability and firmness of the interior and exterior decorative parts, because it is easy to damage the banknotes. Some collectors use potassium permanganate diluent to clean the banknotes with folding dirt. In this way, when developing new compatibilizers, the banknotes will become clean. However, after a period of time, the domestic diaphragm shipments of 1.08 billion Ping banknotes will fade and change color. Others use scotch tape to stick to the back of the broken note. After a long time, the scotch tape will turn yellow and hard, and also damage the face

3. moth proof. The key to avoiding moths is to keep the paper money dry and ventilated. For long-term stored banknotes, they should be read regularly, which can not only provide ventilation, but also check whether there are changes in banknotes; The paper money that has been eaten by insects should be repaired in time. Of course, note money should also pay attention to preventing rat bites, especially in areas with serious rat damage. This requires that paper money should not be kept together with paper or cotton products such as newspapers, magazines, books, etc. to prevent fire and become a good meal for rats

4. anti fading. The key to preventing the paper money from fading is to prevent the paper money from being exposed to the sun. Banknotes will fade in varying degrees after a long period of preservation, which is directly related to the quality of paper and ink. Do not use alkaline or acidic liquid to clean banknotes, otherwise they will fade. Once the paper money fades, it is often irreparable

5. fire disaster. It is particularly important to pay attention to the fire prevention of banknotes. Generally speaking, banknotes should be kept away from fire and power sources, and should not be placed with inflammables and explosives. In this way, in case of fire, there is relatively sufficient time for rescue. It is best to keep it in a safe
