The value of money has always been one of our eternal topics. It involves all kinds of prices. Even in modern times, many people use money to buy ancient coins for collection. At present, people's living standard and economic level are improving, and they have a higher pursuit of the quality of life. For example, the most popular collection of ancient coins, many people do not hesitate to buy them at high prices. For example, the most popular coin at present is daguantongbao. How can we identify it in the dazzling collection market? What's the price? Let's have a look with Xiaobian
how to identify daguantongbao? The identification methods are as follows:
1, look at the copper
most of the ancient coins in China are cast in the form of copper alloy, so the composition of the alloy is different, the coins also show different colors. The copper quality of coins in different times is different, and because of the different smelting technology in ancient times, the ancient coins cast in different areas are also different, and each dynasty has its own characteristics. Generally speaking, coins made of copper zinc alloy are yellow, while coins made of copper tin alloy are cyan. During the Qing Dynasty and the Republic of China, the coins were made in Xinjiang and Tibet, with copper and a little zinc and lead. After casting, the coins were red
There are no more than two kinds of coins seen today: one is excavated, the other is handed down. The excavated objects have been buried underground for many years, and their surfaces are covered with copper rust. Handed down procts also e to oxidation in the air, the surface has a layer of slurry. Black or bronze3. Look at the inscriptions on coins
one of the major characteristics of China's metal coins is that there are inscriptions. It can be said that each type of coin has its own characteristics, and the inscriptions on coins of different times have different writing styles. According to these characteristics, we can check whether they are contemporary coins. In addition, while paying attention to the characteristics of various inscriptions, we can also find out the evolution process and change rules of inscriptions. These rules and characteristics can be used as the basis for identifying the authenticity of ancient coins
4. Listen to the voice
generally speaking, Dao, bu and Yuan Qian in the pre Qin Period were mute. The coins of the Ming Dynasty have not been deeply oxidized, and their sound is clear and loud. If we throw the coins of the pre Qin period on the ground and hear the clear sound, then the money is not very reliable; On the contrary, if the Ming and Qing coin toss is mute, it will be doubted
This method is the simplest one in the identification of ancient coins. Because counterfeit coins are mostly decorated with chemical substances, they often emit an unpleasant and pungent chemical smell, while genuine coins do not The casting of ancient coins in China probably went through several stages of development, such as sub model (earth, stone, copper), mother model (brick, copper), turning sand and so on. Whether it's real money or counterfeit, all kinds of casting methods will leave corresponding traces on the coins. These traces are a powerful basis for us to identify the authenticity of coins today

OK, the above is a summary of the identification methods and prices of daguantongbao introced by Xiaobian. I believe you have a deeper understanding of it.
