Generally speaking, when the jadeite is mined, there is a layer of weathered skin wrapping, and it is impossible to know the quality of the jadeite, which must be cut to know the quality of the jadeite.

But in fact, it is not necessarily the same as jadeite, bloodstone and so on can also have the conditions for gambling stones, and many people will gamble. At the beginning, it was probably an idea that a gambler like Ji Gang came up with, right?

Ji Gang listened to the explanation, his eyes lit up, and he knew that the guy was tempted.

Yang Fan couldn't help but remind that the risk of gambling on stones is too great, and we need to be cautious! The so-called saying "one knife is poor, one knife is rich" is to describe the entertainment and investment nature of "gambling stones".

It can be said that gambling stones are a contest of experience, strength and luck.

"There's a saying in the jewelry world: gambling on stones is like gambling on life. If you win a bet, you will make ten times and a hundred times more, and you will become a rich man overnight; Compared with gambling stone trading, risky transactions such as stocks and real estate are dwarfed by warmth. Yang Fan said to Ji Gang, whose eyes were about to turn red.

Generally, only from the appearance, can not see its true face of "Lushan" at a glance. Even today, with the advancement of science, there is no instrument that can quickly determine whether it is a "treasure jade" or a "ruined flocculent" through this shell.

Therefore, buying and selling is very risky and very "exciting", so it is called "gambling". Gambling wins are very profitable, so this kind of trading has endured from ancient times to the present.

"Where are the gambling stones?" asked Ji Gang eagerly.

Hu Wei can be sure that this is a very qualified gambler, or a gambler among gamblers.

"There are a lot of places to gamble on stones, but your little money is still a little insufficient! A stone in other people ranges from hundreds to hundreds of thousands, and if you want to pick a good piece, I'm afraid your strength is not enough!" Hu Wei said.

Well, Ji Gang already has a plan, accumulating funds, and insufficient gambling funds, which makes people look down on him!

"Contact me when you have these goods in the future. Lao Tzu will teach you a few tricks when the time comes, gambling stones are very skillful, and you also need experience, and you will know when the time comes. Hu Wei is not a pit man, he is also a full gambling lover.

Yang Fan was speechless, this guy is robbing him of his business!

After Ji Gang left, Hu Wei commented on the pile of objects. Among them, there are two very good treasures, and he is willing to give out 100,000 yuan!

One of them was very inconspicuous, the size of a coin, which is what we now call a silver dollar, made of silver.

It was a Xuantong ingot, which was tried to be minted by the Yunnan South Mint in the second year of Xuantong, because it was used as a sample coin, and less than ten coins survived.

Initially, the silver dollars circulating in the Chinese market were imported from abroad. In the late Ming Dynasty, with the development of international trade, foreign silver dollars began to flow into China. By the middle of the Qing Dynasty, the sea ban was gradually lifted, and foreign trade became increasingly prosperous. Under such a historical background, foreign silver dollars began to penetrate into China's inland cities and towns, and the number is increasing day by day.

Hu Wei has read the information, at that time, there were dozens of foreign silver dollars circulating in the market in China, among which the more common ones were: Spain's "Benyang", Mexico's "Eagle Ocean", Britain's "Zhanrenyang", Japan's "Longyang", and the United States' trade silver dollar, which were very miscellaneous.

It can be said that there are still many foreign silver dollars in the people, and collecting them is definitely a huge wealth. You must know that foreign silver dollars are now auctioned abroad, and they are generally very valuable.

The background of the emergence of the Chinese silver dollar was the massive outflow of Chinese silver at that time, and the loss was extremely large. In addition, the sharp increase in trade has led to a decrease in the inflow of foreign silver dollars and an increasing outflow of Chinese silver. Faced with the "silver panic", the Qing court decided to adapt to the situation and mint its own silver dollars.

There are very few domestic silver dollars that exceed one million. And the Xuantong ingots in front of him are the leaders among them, which has been auctioned for more than one million yuan a few years ago, and it is difficult to say now.

"Fuck! You're so lucky to have met such a strange one. Hu Wei couldn't help but say.

Yang Fan was depressed in his heart, and said secretly: Aren't you also wonderful? Fuck! How can I meet all strange?

"There are very few silver dollars in existence, only a few of them! When I saw an old fellow, I picked one up and asked him to transfer it, but he refused to do so, and said that he would treat it as a family heirloom and pass it on from generation to generation. Hu Wei suddenly felt a pain in the face.

In fact, it is not surprising that this kind of one-of-a-kind product that is about to become out of print, if it is not very short of money, it is usually necessary to save it yourself. Especially for the elderly, one is to appreciate it themselves, and the other is to leave some treasures for future generations, which is called blessing for future generations.

However, there are too many fake silver dollars on the market, and everyone should be especially careful when they see this kind of thing.

In recent years, a variety of silver dollar shoes have "emerged" in the collectibles market, especially the "fake Yuan Datou", whose production methods and processes do not hesitate to make molds with Seiko, cast with real silver, and confuse the real with fakes, so that the people who enter the Tao cannot be guarded against.

Some people may think that as long as it is sterling silver, it should not be a fake.

In fact, whether it is a real silver dollar or a fake silver dollar, it is not pure silver, but contains some other metals.

The fineness of real silver dollars is generally about 90% silver, and the silver dollars that reach this content have a white and soft color, and after wiping off the rust, they have a strong silver luster.

Low-fineness silver dollars or fake silver dollars, dull in color, copper with reddish tinge, brass with yellowish tinge, cupronickel with bluish cyan, lead with gray-black, zinc-containing silver dollars bluish-gray.

As soon as Hu Wei looked at the one in front of him, he could determine that this was a genuine Xuantong ingot silver dollar.

He struck the silver dollar, pure and tactful, soft, and calm.

"That's the voice, it's very orthodox. Hu Wei said.

Fake silver dollars with high copper content, the sound of struck is high, the sound of fake silver dollars containing copper and silver plating is sharp and short, the sound of fake silver dollars with high zinc content is brittle and loud, the sound of fake silver dollars with copper or aluminum is sluggish and does not transpose, and the sound of silver dollars with digging and mending is low and dumb or into a "dumb version".

These skills require good auditory skills to recognize.

Sometimes, the difference between the sound is not big, and it takes a very high level of ability to distinguish the truth from the false.

For those collectors, it is important to train a pair of fiery eyes, but it is also important to exercise a pair of ears that are tailwinding. Some things, which look exactly the same, need to listen to the sound and distinguish the rhyme.

"Do you want to collect it?" asked Hu Wei.

Yang Fan glanced at him: "It's impossible for you to take advantage." ”

First of all, get vaccinated with this guy, don't want to take advantage of people, and want to take it cheaply.

"Ah, can I take advantage of you?" If he is a person who does not know how to do it, he can still take advantage of it, people are so powerful, he can't take advantage of it if he wants to!
