In the thousands of years' collection history in China, there have been three national "collections fever", which occurred in the late Northern Song Dynasty, the Kangxi period and the late Qing Dynasty and the early Republic of China. The common characteristics of these three kinds of "collection fever" are that all the emperors and princes and the common people like to collect; Forged artworks and handicrafts can be confused with the real ones; Antiques, paintings and calligraphy are frequently traded in the market; The research results are continuous and the appreciation level is high. Some people say that if measured by this, China is at the climax of its fourth collection. As the saying goes, antiques are hidden in prosperous times and gold is bought in troubled times. Nowadays, collection is considered as the most popular investment method in Chinese mainland after stocks and real estate. Whether it is a businessman's big money or a person's promotion, I hope to get a slice of it. Therefore, the collection market is becoming more and more popular, and the ranks of collectors are also growing. According to incomplete statistics, there are nearly 10,000 collectible associations and collectible markets in China, with 70 million collectors. China has entered the era of national collection! Antiques can now be bought through collectibles market, antique market, art market, auction house and online. However, we should pay attention to the following "five risks": the "five risks" popular in the collection industry: first, the risk of appearance, the collection with good appearance can sell for a big price, and the price of the collection with poor quality will be relatively low; Second, the price risk, the price of various collectibles is not as clear as the stock market, and the same collection will have different prices in different regions. As a collector, we should not only master the market situation of collection all over the country, but also accumulate relevant experience about collection; The third is the risk of fake "goods". For beginners, be cautious when entering the collection market. The rarer the variety, the more careful it is. Ask an expert to help you identify it if you can. The fourth is to keep risks. Due to the influence of climate and some human factors, all kinds of collectibles will face the risk of storage. Some collectibles can not only protect against moisture, but also protect against heat, especially stamps, paper money, calligraphy and painting, etc., to prevent folding, moth-eaten and corrosion of various chemicals. Fifth, the risk of delivery ability. Some collections have poor liquidity. When collecting, we should pay attention to investing in the more popular varieties in the collection market, and try to collect as little or no collections that are not easy to realize in the collection market. When the collection market is in a downturn, it will cause a backlog of funds. "Collection is also a science, which requires comprehensive knowledge and artistic accomplishment in many aspects. No matter which category collectors choose, they need an analogical cultural background. It is inconceivable that a collector is an uneducated person. Collectors should also have a kind of perseverance, put great energy and emotion into the collection, love it before hiding it, regard the collection as a part of life, take protection and research as their own responsibility, and are definitely not hoarders and standard custodians. As for the specific collection knowledge, because there are too many categories of collections, such as stamps, coins, calligraphy and painting, porcelain, jewelry, jade, antiques and so on. And space is limited, it is impossible to introduce every item. As a reference, one of the representative "Knowledge of Coin Collection" is introduced as follows, 1, and the prophet goes on to say. First of all, we should learn the knowledge of coins, enrich our minds and buy books; Secondly, we should be good at using newspapers and all social media to obtain, communicate and transmit information and quotations related to the contents of coins, and master the situation of coin markets all over the country; Thirdly, please ask experts to point out the maze, listen to experts' opinions, make more friends with coin collectors, and skillfully use the brains and experience of wise men. 2. Easy first, then difficult. Coin collection is not a day's work, but a process of gradual accumulation from easy to difficult. People who collect coins for the first time can start with the most familiar coins-the third set of RMB and commemorative coins. 3, first near and then far. The price of ancient coins is difficult to distinguish, and sometimes experts will miss, which is risky. Modern coins, especially commemorative coins, are closest to us, cheaper and easier to collect. Although the number of circulating commemorative coins issued in recent years is more than in the past, because the price is only several times higher than the face value, it is better to buy more and save more. When people gather like clouds for a long time, it will naturally reflect the law that things are rare and expensive. 4. First at home, then abroad. Collecting coins should be based on the domestic market. As for foreign currency, the Central Plains is hard to find and the information is ineffective. In addition, the gap between the economic level and the domestic and international coin collection market has not yet been integrated. Without strong economic strength and abundant energy, it is difficult to get results in a short time. Collecting domestic coins is different, as long as you are careful. 5, first ordinary, then gold and silver. Most of the coins collected abroad are gold and silver coins, because gold and silver coins can preserve and increase value. Starting from the national conditions, our country should start with ordinary coins in collecting coins. The high price of gold and silver coins is unbearable for most collectors. So practice with small money first, cultivate interest, and improve the level of collection and investment. 6, first characteristics and then comprehensive. Setting up characteristics is mainly based on a certain currency and a certain topic, and we should find a new way to collect as much as possible in this range, enrich the connotation as much as possible, and reflect the new value of people without me and people with me. On this basis, the extension is extended, and the characteristics are often produced in platitudes. 7. First local, then foreign. When increasing the variety of coins, priority should be given to local purchase, self-sale, purchasing by relatives and friends, and finally mail order from other places. Even if the local price is sometimes higher, it is safer to see it with your own eyes. Although the mail order price is sometimes attractive, it is difficult to guarantee personal reputation, or the appearance is not satisfactory, or the stone sinks into the sea and there is suffering; For the national staff of government agencies and institutions, the word of mouth is generally good, and you can rest assured that you can mail order. Even if there is a problem, it is better to find a unit to solve it. You can buy a little less for the first mail order and gradually increase it later. 8. Start first and then summarize. When buying and selling coins, people often have the dilemma of buying too much money and not regretting it. Nothing in the world is perfect, and there is no opportunity waiting for you forever, sometimes even a once-in-a-lifetime opportunity. After each choice, we should summarize, digest, absorb, analyze and judge in time and make a plan. We must not take chances and operate blindly. 9. Select first, then operate. Before collecting coins, you should make the following choices: (1) Select coins with small circulation. The less distribution, the greater the increase and the higher the collection value. (2) Choose coins with collectible value for investment. Generally, you can choose commemorative coins, old banknotes, new banknotes, new banknotes with exquisite circulation, coins with special meanings and coins with special numbers. Besides, when collecting coins, we should also distinguish between QingNong coins and stamps.
