How to collect ancient coins?

Chinese ancient coins have a long history and a wide variety. Tens of thousands of coins with different shapes have formed the largest collection category in the field of coin collection today, from the Bei coins in Shang Dynasty, the Knife and Cloth coins in Warring States, the Fiona Fang coins in Qin Dynasty to the mechanism coins in the late Qing Dynasty. But the collection of ancient coins is a university question, and there are many skills to master. Collecting and investing in ancient coins can make money by appreciation, but the premise is to really master certain knowledge of coin collection and must collect ancient coins with value for money. The value of ancient coins is not necessarily related to the time when they came out. There are several factors that determine the value of an ancient coin: first, look at the position of this ancient coin in history, that is, whether it has played a great role in various historical periods; Secondly, it depends on its rarity, that is, whether the amount of this ancient money is very small. There are also coins minted in Liao, Jin and Xixia dynasties in history, and their value is much higher than that of other dynasties in the same period; Thirdly, it depends on whether its material is high-grade, which is relative, but the gold and silver materials in ancient coins are less, and their value is naturally much higher than that of ordinary copper and iron coins; Fourth, it depends on its beautiful appearance, that is, whether it looks beautiful or not. For example, although Wang Mang's regime was a short-lived dynasty, its currency modeling and superficial calligraphy art reached a very perfect height. Although there are still a large number of follwed coins, their market prices are still high; Finally, the collection of ancient money depends on the appearance. Appearance refers to the degree of corrosion of ancient coins and the clarity of Qian Wen and outline. An ancient money is rare and has a good appearance and perfection. Although Qian Wen is special, its collection value will be greatly reduced if its face is unclear and rusted. Mastering the above five elements, the collection of ancient coins will not be too blind. For example, although some ancient coins are very old, their prices are obviously lower than those of some later coins because of the large amount of casting and the large number of unearthed coins. For example, in the Western Han Dynasty, there were about 28 billion five-baht coins minted during the period from Emperor Wu of the Han Dynasty to Emperor Pingdi, which were used for more than 300 years. At present, the price of ordinary products is only 1 to 3 yuan; However, the pricing of coins in the Ming Dynasty, which was 1000 years later than the Han Dynasty, was generally higher than that in the Han Dynasty. For example, the prices of "Xuande Bao Tong" and "Hongzhi Bao Tong" in the Ming Dynasty were higher than those in 20 yuan. There was a large amount of money in the Northern Song Dynasty, but sometimes the price of coins with different proportions and different characters was very different. For example, the general price of copper coins in the Song Dynasty was only about 1 yuan, while the current market price of 10% off seal script and 20% off copper coins was about 80,000 yuan. Because the market price of high-grade ancient coins is very high at present, many rare ancient coins we see in the antique market today are mostly fakes, so coin collectors should be more careful when buying.
