Gao imitation is the heart disease of the lovers of modern silver coins, and it is a lot of new friends who are discouraged from the old silver dollar. Here, I would like to combine my own experience and provide some suggestions and materials for you, hoping to help friends who love modern silver coins. In fact, slowly, you will find that although high imitation is a headache, it is not so "terror" and "incurable". Through our continuous learning and exploration, we can still go to the truth!
First of all, I suggest that novice friends play from the ordinary road goods, don't focus on the top grades, then you will pay a lot of tuition! In the communication with the fellows around me, I found that everyone can't avoid buying counterfeit coins more or less. It can be said that "medicine" is definitely something to eat, because after all, everyone needs a process from entry to proficiency, just like learning to walk will definitely fall, but if you play from a small, big and small head, even if you take medicine "The loss is not big; if you eat "medicine" once, you will have an improvement, it will increase the resistance, slowly, feel it, and it has its own meaning. At this time, you will find that high imitation It is no longer so terrible. At this stage, your own discriminating ability is already good, and then slowly tempered to mature, you can touch some high-end coins. In fact, the method of discriminating is very knowledgeable. It is not clear in a few words. What is more important is not theory but experience and feeling. It is only in the process of "playing" that you can continue to study hard and explore and sum up, in order to truly gain! Knowing oneself and knowing each other can not be arrogant. Then, let's start with the earliest silver coin making tricks. Common fake silver coins generally have the following main methods and corresponding characteristics:
1. Copper plate silver coin: Its shape, size and pattern are completely similar to real silver coins, but the pattern is rough. Grinding it on the stone, it shows the true color of copper; and because it is made of copper, the sound that is knocked out is sharp and whistling.
Second, the lead heart version of the silver coin: is the silver dollar inside the silver skin with lead, with lead to fill the silver. Its pattern is no different from normal silver, but it is slightly thinner. Knocking on each other, the voice is boring, heavy, gloomy and with a voice. Baked with fire, lead is out.
Third, the sandwich version of the silver coin: its outer layer is wrapped in two layers of silver skin, the thickness of the silver layer is thick, and the traces of silver are easily rubbed on the wall. This "sandwich silver dollar" is a more common type of fake silver coin, which is more deceptive. It contains copper, iron, lead and other metal components. It touches the coin heart with two fingertips and blows the coin to the coin. The sound is short, dull and no melodious rhyme.
4. Turning the silver plate: Turn this silver coin to the ground and break it immediately. The broken surface is light gray. The surface of the coin is rough and the image is blurred. As far as the main currency is concerned, the weight is below 20 grams, which is a sanding version. At present, such counterfeit currency is mostly “Yuan Datou†on the market, and Longyang is rare. 5. Acid-etched silver coins: Also known as the “bathing versionâ€, the normal silver dollar is etched with a strong acid such as sulfuric acid or nitric acid to remove a layer of silver. The weight is reduced. As far as the main currency is concerned, it is less than 25 grams. The pattern is blurred or floating white, and the pronunciation is slow. The beginners are deeply affected and should be vigilant.
Sixth, the autonomous version of the silver coin: it is a privately minted silver dollar, and the Beiyang is made of long-range silver coins. It was minted in Hainan Island during the Republic of China. The coin market in Taiwan is very common. It is characterized by a silver color of less than 80% and a high voice. Because it is rare for coin collectors in China, it is easy to "eye".
Seven, silver-plated silver coins: Because the surface is silver-plated, the pattern is clear, almost identical to the real silver coin, it is difficult to distinguish from the image and the color. However, although it is finely crafted, the proportion cannot be balanced with real silver, so as long as the weight is called, it can be revealed. In terms of the main currency, the weight is generally 20 to 22 grams, and the true silver coin will not be less than 25 grams even if it is worn out (the standard weight of the main currency such as Guangxu ingot and big head is 26.6 grams).
Eight, change the version of the silver coin: This silver coin can not be identified by the naked eye, whether it is listening to the sound or testing the silver color, or see the pulp is old. Because most of its subjects are true coins, it is extremely confusing. However, under the high magnification magnifying glass, the key words and patterns are carefully observed. The false ones often leave traces of knives, and the reformation of the pulp is often inconsistent with other places. This method of falsification is to engrave or dig the original graphic of the real silver coin, and then paste the special silver font and ornament to pretend to be a treasured silver coin for profit. For example, if you use the ordinary big head to change the Gansu version plus the big head or the signature version of the big head, you can use the ordinary 23-year ship to change the 21-year "three birds" or 24 years of shipping.
