Why were gold and silver coins made in ancient times?

Since ancient times, gold and silver coins have been playing. The inks were used as currency. It was more used in the times of King, Kings. But have you ever wondered why gold and silver were chosen as currency? What is the reason behind it? Let us study on the basis of research given by some researchers through this article.
Google source

The coin has been part of our history for nearly 3000 years, which provides valuable insight into the development of chemical technology. Analytical chemistry can be explained on the basis of why and how gold and silver coins started forming.

Let's study about the trend of gold and silver coins on the basis of researchers.

Professor Andrea, of the Inorganic Chemistry of University College London, told him on the basis of periodic table or periodic table. But do you know what the periodic table is.

This is a mechanism to show chemical elements in the form of a table with their corresponding characteristics. In the periodic table, the chemical elements are decorated in the increasing order of atomic number and the spiral, primary group, has been classified in the secondary group. There are 118 known elements in the current periodic table. First Russian chemist Mendeliff introduced the spiral law in 1869 and explained the elements as a table.

Now Andrea says that if we look at the right hand side of the periodic table, these chemical elements are shiny and they are placed in the blue circle. These are chemically stable elements. There is no change in that i.e. there is no change in them. This is their specialty too. But this is also the Noble Gas Group. Do you know that these gas are odorless and colorless? Their chemical reaction capacity is also low.

Let us tell you that all the elements of Group Zero are called Noble Gases. The list includes Helium, Neon, Argon, Krypton, Jenon and Radon. For this reason, it is difficult to use them as money. These coins can not be kept in pockets, purses, etc. Such a currency can not be transported from one place to another because they are colorless, it is not easy to identify and if it comes in contact with air. Then they will become extinct.

Mercury and bromine metal could not even make coins. Let's see the reason: Mercury and Bromine are in liquid state and are poisonous. Do you know that all meteoids are either liquid, soft or poisonous. If seen, gas, liquid and toxic chemical elements from the periodic table will be seen incomplete.

What is the difference between AD and BC?

If we talk about non-metal or non-metal elements that are around the gas and liquid elements in the periodic table. They have the specialty that they can not be called neither can nor be form of coin. These are not soft like the other metal or metal, so it is difficult to give shape or a form of coin can not be given. Therefore, their currency was not created.

There were also elements in the periodic table which can be made in the form of coins or currency but their ability to react to chemicals is very high. These chemical elements are called metal. Like lithium metal are so reactive that they react as soon as they come in contact with the air and there may be a fire. So they could not even make coins.

Now if you talk about alkaline, it is easy to find anywhere. If the currency is made from them, then no one can prepare it. Also, radioactive elements can not be used as coins. Iron coins were easy to find, but they are found in such quantity that no one can make them. That's why it's not even trend.

Now in the end, the five elements are saved which are not easily available: Gold, Platinum, Radium and Plaidium. All these elements are precious. In all these radium and plaidium could be used as currency but they were discovered in the nineteenth century, due to which they were not used in ancient times. Gold and silver were easily found in ancient times. Therefore, they were used as coins.

How did gold and silver coins start in India?

In the ancient India in the 6th century BC, coins first became the first of coins. Since that time, coins were considered to be the most universal incarnation of money. First of all, the coins were made of electrum, which were a natural yellow color mixture of gold and silver, which was then mixed with silver and copper.

Let us tell you that ancient Indians, Chinese and Ladies (from the Middle East) were the earliest issuers of coins in the world. The first Indian coins were identified which were called Puranas, Karshapanas or Pana. These coins were mined by the Mahajanapadas (Republican Kingdoms) of ancient India in the 6th century BC. These included Gandhara, Kuntala, Kuru, Panchla, Sakya, Surasena and Saurashtra.

Did you know that the oldest Kushan coin in India was usually built at the time of Vima Kadphises? The symbols of Kushan are generally depicted in Greek, Mesopotamian, Zoroastrian and symbolic forms drawn from Indian mythology. Among these, the major Indian deities of Shiva, Buddha and Kartikeya were also portrayed.

Analysis of coins on chemical basis

As we know that 700 AD The first metal coins that were visible in the Middle East were made of gold and silver. These two metals were made accessible at a time when chemistry and technique of metal extraction from binary metal compounds was unknown. It was also seen that in ancient times when gold coins were chosen for research then it was exactly the same as in ancient times. There was no effect of the atmosphere or any kind on them. Over the centuries, the base metal fe, Cu, Ni, Zn, Al, Sn and Pb have been used as a major component in minor alloy components or coins. During British times, gold was generally mixed with copper to give hard garment alloy. Platinum made only a brief appearance in the form of coin metal. Some high-priced coins in Russia were built in the middle of the 19th century, when platinum was found in the Ural Mountains.

As the chemical and technical knowledge improved, the stability of the coins increased demand. In modern times, the metal and alloy used in coin production was very essential. Due to the very small traces of non-metals such as carbon, sulfur or phosphorus in coins, the coins could have been cracked quickly, which could not be modernized by the coin-striking devices of modern technology, they were driven by high speed and pressure.

In the last 60 years, electroplated iron and steel coins have appeared in many countries. This is because the demand for providing low-value coins for the rich consumers during the war years had increased and the costs of making these were reduced. Since 1992, British 'Bronze' coins were started with copper-plated steel.

Thus, we can see that the coins of gold and silver coins were from ancient times but at that time there was no such technique which made some more metal coins. Gold silver was easily found at that time and coins made of these were not bad, so they were used. Subsequently, coinage began to be mixed on the basis of new technology and equipment. Some researchers told him on a chemical basis that it was a chemical reason to use gold and silver currency in ancient times except for the rest of the other elements or metals, even though people were unaware at that time, but now it can be described chemically as if As mentioned in the above article.
