Can the fake Yuan Datou blow loudly, can Yuan Datou really blow with his mouth

It may also be that the method of blowing is wrong, and this alone cannot identify the authenticity of the silver dollar.

Blowing is only one of the methods of authenticity of silver dollars, and can only be used as a reference.

There are other more practical methods, such as looking at materials, fonts, patterns, toning, edge teeth, and so on. Be sure to make a comprehensive judgment!

In the middle and late Qing Dynasty of China, after the silver yuan was introduced into China from Spain, Mexico, etc., it officially began to manufacture China's silver yuan during the Guangxu period of the Qing Dynasty, commonly known as "Longxiang", and then circulated in the market. Most of the official money bureaus of various provinces in China, as well as the private money banks and silver buildings, have comprehensively examined the fineness of silver yuan from the color, sound, weight and method of stamping, and summarized a set of systematic methods for identifying the authenticity with Chinese characteristics.

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".

3. Test with specific gravity method.

The specific gravity of ** is lower than that of platinum, and higher than the specific gravity of other common metals such as copper, lead, and zinc. A silver yuan of Guangxu Yuan Treasure Treasury is generally between grams and 27 grams, and the weight of one or two silver dollars is 36 grams, and the error of real silver yuan will not exceed grams. The fake silver round ones are doped with a larger proportion of other metals such as copper, silver, and zinc; Knowing the specific gravity of different metals, as long as you compare the fake silver round with the real silver round of the same volume, and gently touch it with your fingers, you will find that the fake silver round is light and the real silver round is heavy.

On a scale, a fake silver dollar is 2 to 5 grams lighter than a real silver dollar.

Yuan Datou's five circles are not broken when they are thrown on the ground, they are blown loudly, the magnets are not sucked, and the edge lines are uniform, which is fake.

Yuan Datou silver dollar will make a sound when it blows.

Because the air rubs against the metal, it causes the metal to vibrate and make a sound. So even if it is a fake Yuan Datou, most of them blow loudly, but the sound will be different, such as the sound of the tin version is sharp, the copper core is low, and the lead version is difficult to blow, only long-term play can find the law.

What can be blown must be a silver dollar, but it is not necessarily a real silver dollar of Yuan Datou. Because there are also modern Yuan Datou silver dollars imitated with real silver, these modern fake Yuan Datou silver dollars can be blown like the old Yuan Datou silver dollars because they are real silver. It needs to be combined with the phase and manufacturing process to determine.

(1) Principle: The combined effect of ductility and elasticity of the silver dollar is conducive to vibration, and when the silver dollar is blown sideways, it is equivalent to giving a lateral force to the edge of the silver dollar, and the various parts of the radius of the silver dollar resonate with each other, and the resonance is transmitted through the air to form an audible sound.

2) What will blow is not necessarily true. Being able to blow is not a means of identifying a silver dollar, because anything metallic, such as iron, will resonate and make a sound.

Identification methods: 1. Silver counterfeiting.

To distinguish the authenticity of Yuan Datou, we first start by identifying the authenticity of silver;

2. Slurry identification.

There is a layer of oxidized silver on the surface of the silver coin, which is often referred to as a bag;

3. Listen to the sound and distinguish the fake.

Use the tips of your thumb and index finger to the center of the coin, or hold the middle of the coin with your middle finger and strike it with another coin, and the sound is soft and gentle.

4. Rust color identification.

After a silver coin is out of circulation, it will rust if it is not stored properly.

5. Weight and diameter identification.

The Yuan Datou silver coin is 39mm in diameter and has a standard weight of grams. However, there are slight differences or reasonable wear and tear in the implementation of various places.

Can you still judge the authenticity of Yuan Datou by blowing Yuan Datou and listening to the sound?

As long as it is silver, it can basically be blown, and the key depends on the amount of silver. The slurry layer is generally not thick, and it does not affect the sound you make when you blow it.

**There is no way to distinguish the authenticity at all, it is recommended to go to a special appraisal agency to construct, identify, or find some anchors on the live broadcast for identification.

Distinguish the authenticity of Yuan Datou.

1.You can look at the shape, you need to observe whether its color is uniform, whether the pattern lines are smooth, and whether the thickness is consistent.

2.Looking at the weight, the standard weight of Yuan Datou is grams, and you can weigh it according to this standard to judge the authenticity of the silver dollar. 3.You can also distinguish the authenticity of a silver dollar by its sound, and the real silver dollar can make a crisp and soft sound.
