blue opal jewelry wholesale Yuan Shikai Feilong Coin is divided into authenticity through the following aspects:
(1) Silver
(2) Sound
(3) Packing
(4) Side tooth
(5 ) Machine casting
The identification of silver dollars should consider many factors:
(1) Silver
silver, which is the metal color presented by silver circles. The silver -round silver white is moisturized, the luster is soft, and a natural color is revealed in the color. Although fake silver balls are made of silver, due to the formula of metal components, its silver and old silver circles are different. Generally, blue is green, the luster is strong, and the color is hard and dazzling. Through more observations, it is easier to master.
(2) Sound
Net to hit the real silver circle, the frequency of the sound is low, and it will make a long and soft and pleasant sound. Due to the problems of the metal component formula and the different manufacturing process, the sound of the silver circle is always pointed and the sound is high. However, it should be noted that some real silver circles also have bad sounds, commonly known as "dumb version". Sound is just one of the basis for identifying the silver circle.
(3) Bao pulp
The silver round paste is a layer of dark attachment caused by oxidation during the use of silver circles. It is very thin, but the traits are stable and it is not easy to fade. Modern fake silver circles use technologies such as computers and infrared scanning to make molds. Its weight and patterns are basically close to the real product, so the identification of silver circles is particularly important.
(4) side teeth
The sidelines of silver round have two major functions: anti -counterfeiting and preventing metal. In the appraisal of Yinyuan, the side teeth are a very important part. A common fatal weakness of modern high imitation silver circle is that the side teeth cannot pass. The side teeth of the real silver round are neat and uniform and slightly arc. Generally, there are natural wear marks, and there are generally packed pulp in the side teeth. The side teeth of the fake silver round are not neat, uniform enough, no arc, very hard, and there are many new people in the side teeth as machining traces. Observe more, it is not difficult to find.
(5) Machine casting pattern
The machine casting pattern is a texture produced by the mechanism coin during stamping molding. In the assessment of coin -quality phase level, the performance of the machine casting pattern is one of the important factors that affect the level. It is not familiar to the collection of silver rounds through the machine casting pattern.
Plove the cause and characteristics of the machine casting pattern first: The manufacturing machinery of the silver circle is a very stressful hydraulic machinery. When the germ cake of the silver coin is put in the steel mold, the mechanical is pressed against the steel mold. Due to the mold of the mold, the mold is due to the mold of the mold. The volume is certain. After the embryo cake is under tremendous pressure in the mold, it will only extend from the center of the steel mold to the surroundings, which will generate a fine line from the center of the embryo (the center of the silver circle) to the circle. It is the cause and process of machine casting.
The modern counterfeit silver circle is also formed by machine stamping, but because of the advanced conditions of its modern machinery, its pressure is far from reaching the pressure made by real silver circles, so it is difficult to produce vitamin casting. True silver round, the cast pattern with light silver round is generally very obvious. Even if there is a wear silver circle, although a large area of machine casting pattern is not obvious, around the inner teeth of the silver circle, due to the protection of the inner teeth, the machine casting pattern is not easily worn. It is not difficult to find the legacy of the machine.
wholesale price of jewelry in lagos The key is whether it is true currency and whether there is natural circulation wear. Then, then, then
brazilian jewelry set wholesale For rare products, it is actually the best distinction, because there are only two cases, low imitation and high imitation.
(1) Due to the high casting cost and low imitation, the selected casting materials generally do not use silver materials. Instead, they are used for white copper, brass and other materials. The workmanship is extremely rough. I have seen the real product at a glance.
(2) As for the high imitation, due to the rare, the opportunity for most people to contact, and some experts are not sure. Generally, they choose to send review.

The silver round paste is a layer of dark attachment caused by oxidation during the use of silver circles. It is very thin, but the traits are stable and it is not easy to fade. Modern fake silver circles use technologies such as computers and infrared scanning to make molds. Its weight and patterns are basically close to the real product, so the identification of silver circles is particularly important. After many years of collecting silver circles, observation and summary found that the real pulp is under the high -power magnifying glass, showing that the state of the packet attachment is relatively loose, and it is stacked with oily sweat. The gap in the pattern and the inner teeth is particularly obvious. In order to overcome the fault of the silver thief's bright silver thief, it is often used to make the previous layer of fake packets in chemistry or other methods. This kind of fake paste is under high -power magnifying glass, showing the monotonous and flat layers. In fact, the color changes caused by the surface of the surface. It is important to master this priority.
(4) side teeth
The sidelines of silver round have two major functions: anti -counterfeiting and preventing metal. In the appraisal of Yinyuan, the side teeth are a very important part.

The machine casting pattern is a texture produced by the mechanism coin during stamping molding. In the assessment of coin -quality phase level, the performance of the machine casting pattern is one of the important factors that affect the level. It is not familiar to the collection of silver rounds through the machine casting pattern. First introduce the cause of the production of the machine casting and its characteristics: the manufacturing machinery of the silver circle is a very stressful hydraulic machinery. When the germ cake of the silver coin is put in the steel mold, the mechanical is pressed to the steel mold. Because the size of the mold is certain, the size of the mold is certain. After the embryo cake is under tremendous pressure in the mold, it will only extend from the center of the steel mold to the surroundings, which will generate a fine line from the center of the germ cake (the center of the silver circle) to the circle. This is the machine casting pattern. Reason and process. Although some of the modern counterfeit silver rounds are also machine stamping, because of the advanced conditions of modern machinery, it does not reach the pressure of real silver circle, so it is difficult to produce the firing pattern. True silver round, the cast pattern with light silver round is generally very obvious. Even if there is a wear silver circle, although a large area of machine casting pattern is not obvious, around the inner teeth of the silver circle, due to the protection of the inner teeth, the machine casting pattern is not easily worn. It is not difficult to find the legacy of the machine.
