Coinage: the history and characteristics of the process

The article describes what coin chasing is, what equipment is used, and also the issue of making souvenir coins.

Ancient times

coinage

Since time immemorial, people have beentrade, in the process of which the need arose to create a universal exchange equivalent - money. Initially, their role was played by precious metals, or rather, their bars (similarly called "hryvnia" and used in Russia), wire or just pieces. But, soon they were replaced by coins, with a fixed weight and, as a consequence, nominal. They were also made of precious metal, and coinage was an invariable attribute of every strong state. Naturally, the appearance of coins varied greatly, depending on the country or region.

Nowadays

chasing souvenir coins

And with the advent of paper money into our lives, coins were not squeezed out of circulation. However, almost all over the world they are now made of ordinary iron or an alloy of non-ferrous metals.

Such a process as the coinage of coins in Russia,The State Mints are engaged. The appearance of coins was always directly dependent not only on the era, but also on the political system in the country. Representatives of various political regimes in the course of history introduced their own banknotes with the appropriate attributes. But, in addition to a purely practical production, there is another kind, which has an important cultural and historical significance - the coining of souvenir coins.

Often among them are the jubilee ones, whichalso are operating monetary signs, but differ from others by engraving or form. Most often their release is confined to some historical event in the world or the country. And souvenir, value as such, have only as a collection of exhibits. But sometimes they are made from precious metals, such as silver or gold. Pay them in the store certainly will not work, but you can, if you want, exchange them in a bank for an equivalent price or sell them at a pawnshop.

Now, by the way, the production of souvenir coinsprivate firms also took up their jobs. The range of their services is very wide, starting with the drawing up of a unique sketch, ending with a direct transfer to the workpiece. The material can also be selected.

Manufacturing

coin chasing equipment

In fact, the term "coinage" is not entirely true. The so-called process of transferring an image onto a workpiece by hammering a hammer. But this method is ineffective in industrial production and is suitable only for making small money. In addition, the image often turned out to be blurry.

Now, when making coins, so-called priming (application to ribs of strips) and embossing are used, when the necessary drawing is transferred by means of the press to the workpiece.

Initially, screw presses were used in the Middle Ages, when by means of the rotation of the levers and there was an embossing, but the process is long, and for industrial manufacture of coins is not suitable.

But at the beginning of the XIX century the engineer Nevedomsky inPetersburg machine was created for coinage with a cranked lever. Its productivity was about 70 coins per minute, which was more suitable for streaming money.

Coinage. Industrial and amateur equipment

Simply put, industrial equipment is the same press, but with a high degree of automation. In his work, the main criteria are the high speed of work and the absence of marriage.

Amateur equipment is compactApparatuses whose performance is much lower. But the image quality is given paramount importance. Such machines offer a lot of companies, so anyone can set up production of their souvenir coins.

True, do not forget that the forgery of existing currency is prosecuted by law.
