The identification of copper coins can be carried out from the following 8 aspects:

Look at the copper quality

Look at the color of the pound

Look at the money inscription< /p>

Many coins have inscriptions, which is a major feature of our country’s coins, and the fonts of coin inscriptions in different eras have their own characteristics and writing styles. Based on these characteristics, it can be tested whether it is a coin of the same era. In addition, while paying attention to the characteristics of various Qianwen, we can also find out the evolution process and changing rules of Qianwen. These rules and characteristics are important basis for identifying the authenticity of coins.

Listen to the sound

Sound identification is also one of the important methods for coin identification. Due to the age, the ancient coins have lost all their fire and energy. When struck, the sound has no translucency, and when thrown on the cement floor, the sound is mute. Although the newly minted coins have forged ancient era names, they must have a transflective sound when struck. Coins counterfeited by methods such as inlaying and stitching are pieced together, and there may be damage inside the coins. Some are even made of two different metals, so just drop them lightly on the table, or use a When metal is struck, a shell-breaking sound will be made, but there will be no clear and loud metal sound.

Smell

Smell identification is also one of the ways to identify counterfeit money. Genuine coins have been handed down from generation to generation for a long time, and the fire during smelting has long disappeared, and there is no fire when smelling. Zhan coins that have been buried in the soil for a long time often have green rust when they are first unearthed, and have an earthy smell when smelled. Because the forged ancient coins have not been smelted for a long time, the coins often retain the heat of the smelting process. If it is a counterfeit coin, there will be no earthy smell when sniffing it. Fake rust can be painted with glue, rosin mixed with pigment, or glue paint. When sniffing carefully, there will be a special smell of pine, glue or paint on the rust. If counterfeit coins are boiled in water and then smelled, these special smells will be more obvious. Pseudo-rust that grows after being soaked in sulfuric acid, acetic acid, etc. is not only loose in texture and easy to fall off, but also has no earthy smell, but often retains the smell of acidic liquid. As for the ancient products made by fire forging, cooling and smoking, they will leave a special smell of fire and smoke.
