How to determine whether the ocean is real or not

1. Sound. Striking the True Silver Circle, the frequency of the sound is low, and it will produce a long, soft and pleasant sound. Due to the problem of metal composition formula and the different production process, the sound of the fake silver round is always relatively sharp and the frequency of the sound is higher.

However, it should be noted that some real silver yuan also has a bad sound, commonly known as the "dumb version". Sound is only one of the bases for identifying silver dollars.

Second, silver. Silver, that is, the metallic color of the silver round. The silver white of the real silver round is moisturized, the luster is soft, and the color reveals a natural color.

Although the fake silver round is ** manufactured, but due to the formula of the metal composition, its silver and the old silver round are different, generally white with blue, strong luster, the color is stiff and dazzling, in the jargon, it is with "thief light". This point is relatively easy to grasp by observing a lot.

You can listen to the sound of the ocean when you knock on the ocean, and when you hit the ocean, the real ocean sound has a low frequency and will make a long, soft, and pleasant sound. After the fake ocean is struck, the sound emitted is high in frequency and relatively sharp.

The real ocean silver is white, but the white looks more moist and the luster is soft, and it will reveal a natural color. The fake ocean white is translucent with a strong luster, and the color is stiff and dazzling.

The ocean can also distinguish the true from the false by looking at the pulp, the ocean has been circulating for a long time, and a uniform layer of slurry will be formed on the surface, and this layer of slurry is not easy to fall off. The fake ocean generally does not have the pulp, even if the slurry is imitated, the pulp can be easily rubbed off by hand.

It can be sent to Beijing Gongbo for boxing rating.

First, look at the color.

The fineness of real silver round is generally about 90% silver, and the silver round that reaches this silver content is white and soft in color; After rubbing off the rust, it has a strong shine. Silver round or false silver round with color base, dull color, silver round with red copper with reddish band, silver round with brass with yellowish yellow, silver round with white copper with bluish cyan, silver round with lead with grayish black, silver round with zinc with blue-gray.

2. Listen to the rhyme.

The sound produced by the real silver round after striking is pure and tactful, soft, and feels calm. The sound of the fake silver round with high copper content is high after tapping, the sound of the fake silver round with copper and silver plating is sharp and short, the sound of the fake silver round with high zinc content is brittle and loud, the sound of the fake silver round with copper or lead is sluggish and does not turn the tone, and the sound of the silver round with digging and mending is low and mute or into a "dumb version".

The side teeth of the real silver dollar are deep and uniform, and the side teeth of the fake silver dollar are shallow, and the spacing of the side teeth is not the same. In addition, you can also listen to the sound, when the silver dollars are struck on each other, the real silver dollar will make a crisp, pleasant, and tactful sound, and the fake silver reed slow knowledge yuan will make a sharp, harsh, or dull sound.

Look at his lines, look at his weight, and how old and new. The lines are clear and there are no obvious edges and corners, and there will be no discoloration when soaked in water, and the current ocean is hardly very new. Give me a bottle of Budweiser, and I can keep making it.

The real ocean is easy to get old because of silver, and many of the fake ones are nickel-chromium alloys, which make people feel very new. The true ocean is softer, while the false ocean is hard.

Can he understand that you say so much on the first floor? It is struck between coins, and the sound of different materials is different. However, it is difficult for beginners to understand, it is recommended to weigh it, it should be above the gram to be true, so it is more reliable!

How to distinguish the authenticity of the silver ocean:

1. Listen to sounds. It is distinguished by the sound of silver dollars hitting each other. Gently press the ** of the silver dollar with one fingertip upward, and hit the edge of the silver dollar with another silver dollar, the sound is light and crisp, soft, and it is a real silver dollar.

If the sound is high-pitched and has a copper sound, it is a low-content fake silver dollar containing a lot of copper. If the voice is low and hoarse, and the periphery is inconsistent, it is a foreskin and a fake silver dollar that has been dug up. In general, the sound of fake silver dollars is mostly high-pitched and short, muffled.

2. Look at the appearance. Look at the shape and structure, pay attention to observe whether the color, pattern, pattern, size, thickness and so on of the silver dollar are normal, whether there are traces of pickling, filing, foreskin, digging and repairing and whether there is a private version of the silver dollar, etc., generally speaking, the diameter of the fake silver dollar is slightly smaller than the real silver dollar, as long as the same volume of fake silver dollar and the real silver dollar are compared, you can distinguish the authenticity.

3. Check the edge teeth. Since the real silver dollar is a mechanism version, the steel is slightly lame, and the regularity is uniform; The teeth of the counterfeit coins are rough and uneven, and some have traces of partial file repairs. As long as you are careful, it is still relatively easy to distinguish with the naked eye.

If the real "Yuan Datou" has one fine tooth among the two coarse teeth on the side teeth, the thin teeth of the fake "Yuan Datou" are blurred.

4. Weighing. The standard weight of a silver dollar should be 26 5 grams and a fineness of 88. A normal silver dollar, after being worn out by circulation, should also weigh 25 8 grams.

Anything weighing less than 25 8 grams and a fineness of less than 84 is either washed, filed, foreskinned, or dug up silver dollars, or counterfeit.

5. Acid test. If you put a drop of nitric acid on a silver dollar, if you find that the silver dollar is bubbling green or black, it is a deficiency or a fake silver dollar. As long as the copper core silver dollar touches nitric acid, it will lose its luster.

If it is silver-plated, the silver-plated surface is easy to peel off, and the peeling part is very easy to rust. In short, to distinguish between real and fake silver dollars, you should remember this mantra: "Weigh it, look at the color, drop nitric acid, and gently touch it to listen to the sound".

Three tricks to identify the authenticity of the silver dollar Experts said that the counterfeiting techniques of the silver dollar are generally nothing more than full counterfeiting and semi-counterfeiting, all counterfeiting is the use of modern materials to make fake cultural relics silver dollars, and semi-counterfeiting is to slightly transform the ordinary cultural relics silver dollars, it is recommended that the three tricks of seeing, weighing, and listening can basically identify the authenticity and falsehood. Trick 1: Two Views and One Observation The so-called two views are to look at silver and charm.

Ye Hui took out two genuine "Sun Yat-sen Portrait Silver Dollars", only to see that the color of the genuine product was white and soft, and the paste could be wiped with hands or a soft cloth, which could reflect a strong bright light. The fakes are mostly white copper, lead, tin and other alloys, and the color is blue-gray or dry white. Secondly, most of the genuine coins are carved by engraving masters, which are stamped by machines, with exquisite patterns and deep and orderly teeth.

Ye Hui pointed out that it is necessary to see every detail clearly, and it is best to use a 20x magnifying glass to observe whether the surface of the coin is smooth and clean, whether there is trachoma, whether the subtleties of the image are missing or altered, and some counterfeiters change the six-pointed star to a five-pointed star. Trick 2: Weighing The so-called weighing is weighing, this kind of silver dollar generally weighs between grams and 27 grams, and the error between each real silver dollar will not exceed grams.

Fake silver dollars are mixed with a large proportion of copper, lead, zinc and other metals, so as long as you compare the same volume of fake silver dollars with real silver dollars, with a light finger, you will find that fake silver dollars are light, real silver dollars are heavy, generally speaking, more than 1 gram lighter is a fake. Trick 3: Listen to the rhyme Listening to the rhyme is one of the main ways to distinguish the real from the fake.

It is understood that the fake silver dollar material is divided into silver.

Through his own known experience, he tells everyone about the authenticity of silver dollars, not an expert, and there are not too many ornate identification methods, from the simple and crude identification methods of the people.

Mainly look at the color, the real and fake colors will be recognized at a glance.
