We often see the following scene on the TV series, some rich and noble families have eaten and drunk enough in the restaurant and are satisfied to go downstairs, and before leaving, they generously throw out a piece of silver to check out, shouting "Don't look for it!" And the shopkeeper immediately used his mouth to bite the piece of silver to check the authenticity, and then immediately smiled and shouted respectfully: "The guest officer walks slowly!" ”
As an ancient hard currency, silver this metal is active on the stage of history, the first few dynasties, in fact, or copper coins are mainly traded, in 221 BC, after Qin Shi Huang unified the six kingdoms, abolished the sword coins and other old coins between various countries, using square holes and half two coins circulated and used.
With the discovery of the New World by Columbus in the 15th century, European colonists mined a large amount of silver in the Americas, and China had a large amount of exchange and trade with Western countries, so during the Ming Dynasty, a large amount of silver flowed into Chinese society, and it was during this period that silver became the legal circulation currency stipulated by the government.
Therefore, the use of silver is more common in Chinese society, and the silver that we see in ancient times today is basically a product of the Ming and Qing dynasties, and at this time, silver has a basic and stable value.
Many people's impression of Guda silver two, must be very smooth and heavy, presented as horseshoe-shaped yuan treasure, or conveniently stacked neatly rectangular silver blocks, in fact, the real silver is not like this at all, specialized archaeologists said that they will tell you that in the Ming and Qing tombs unearthed today, except for a very small number of silver two, most of them are covered with dirt and tooth marks on the surface, black and not slippery broken silver. It will subvert your imagination
The yuan treasure that everyone sees on the TV series is specially dedicated to the imperial court, or the reserve silver of the national treasury, and this is the real appearance of the silver circulating in the market, which is convenient for finding change. Like some small gravel, it is not as beautiful as imagined.
But all things with high profits will receive the prying eyes of outlaws, ancient people naturally also have counterfeit people, mixed with moisture in silver, a lot of silver are passive hands and feet, some outlaws are just on the outside of a simple wrapped layer of silver shell, and inside is infused iron or copper, this is also easy to identify, experienced people can weigh the weight in their hands, but there is also a kind of difficult to identify, some people in the casting of metal, the tin or copper together into the silverware, It is difficult to judge whether this is true or false from the external weight.
Therefore, the best way to test the silver is to take a bite, the texture of the silver is generally soft, can leave tooth marks on it, if you feel the teeth, it must be involved in other metals, but also can not be too soft, otherwise it may be put tin metal. So what we see now, we find that there are a lot of tooth marks on the silver two, which is actually how it came. It looks neither aesthetically pleasing nor hygienic.
Even if the ancient silver two is not adulterated, because of refining technology and other reasons, its impurities are still a lot, although the silver itself is an inactive metal, but after hundreds of years, it will still occur in the air oxidation reaction, those with impurities of silver block reaction speed is faster, which is why the silver surface will be blackened.
The skin is deteriorated and blackened, coupled with the surface is covered with potholes and tooth marks, and there are more miscellaneous things inside, which greatly affects the value of these silver two, which is the true face of the ancient silver two, will everyone still want them?
