1. First of all, when identifying the authenticity of one yuan coin, you should have a clear understanding of the patterns used on coins of different years. Because the technology of making coins is a state secret to a certain extent, it is generally difficult for counterfeiters to master all of them. Therefore, fake coins generally have more or less flaws. The lines are rough, either with irregular strokes and so on.
2, followed by the true and false of one yuan coin can also be judged from the color. The color of the 1 yuan coin is nickel -white, and the fake coins are compared because the material used is different in color differences. Obviously, whether it is a stainless steel or other types of materials, the color of the fake coins of the material is either too bright or bright. The color will present a relatively gray effect. In addition, if you have a certain understanding of the manufacturing of coins, you will know that the centerline of the front and back patterns must be symmetrical.
3, in the end, the identification of one yuan coin can also be judged from the thickness of its own, but in normal words, everyone needs to pay attention to itself, and at the same time Essence Fake one -dollar coins are generally not grasped because of their limited technology, and the phenomenon of uneven thickness is extremely common.
The expansion information:
The currency pattern of RMB is very fine, uniform currency quality, smooth and shiny. In particular, the casting of the national emblem and wheat ears is very clear, while the effect of fake coin casting is more vague. Take 1 yuan of RMB coins as an example:
1, patterns: real 1 yuan coin's stamens, rice ears, national emblems, Tiananmen and other patterns are clear, bumpy, and fake coins are rough, the patterns are blurred Essence In addition, the front and back patterns of the true 1 yuan coin are consistent, and even if there is an error, it is very small; but the fake coins usually have different oriental patterns in different sides, and they seem to be asymmetric.
2, the edge of the frame: The thickness of the real coin is uniform and smooth, while the fake coins are usually uneven thickness, and the edges are cut and worn.
3, Material: Real 1 yuan coin is nickel -packed steel, which can be sucking with magnets, otherwise it must be fake coins; The general clear traces of the pencil line will appear. Of course, some fake coins with iron or non -lead can not be verified by this method.
4, stacking: Real 1 yuan coins are very flat when stacked together, but because of the inconsistency of the thickness of the coins, it will produce a sense of uncoordinated feeling when it is stacked in the real currency.
Perhaps Hall sensor. It was detected by a magnetic field, but it was only some personal level testing coins. As for the bank's security level, I don't know how to know it!
