Money was historically an emergent market phenomenon that possessed intrinsic value as a commodity; nearly all contemporary money systems are based on unbacked fiat money without use value. Its value is consequently derived by social convention, having been declared by a government or regulatory entity to be legal tender; that is, it must be accepted as a form of payment within the boundaries of the country, for "all debts, public and private", in the case of the United States dollar.
A coin is a small object, usually round and flat, used primarily as a medium of exchange or legal tender. They are standardized in weight, and produced in large quantities at a mint in order to facilitate trade. They are most often issued by a government. Coins often have images, numerals, or text on them. The faces of coins or medals are sometimes called the obverse and the reverse, referring to the front and back sides, respectively. The obverse of a coin is commonly called heads, because it often depicts the head of a prominent person, and the reverse is known as tails.
A coin is generally made of metal or an alloy, or sometimes of human-made materials. Precious metal–based coins had the advantage of carrying their value within the coins themselves. On the other hand, they induced manipulations, such as the clipping of coins to remove some of the precious metal. (Full article...)
The ruble or rouble (/ˈruːbəl/; Russian: рубль, romanized:rubl', IPA:[rublʲ]) was the currency of the Soviet Union. It was introduced in 1922 and replaced the Imperial Russian ruble. One ruble was divided into 100 kopecks (копейка, pl. копейки – kopeyka, kopeyki). Soviet banknotes and coins were produced by the Federal State Unitary Enterprise (or Goznak) in Moscow and Leningrad.
In addition to regular cash rubles, other types of rubles were also issued, such as several forms of convertible ruble, transferable ruble, clearing ruble, Vneshtorgbank cheque, etc.; also, several forms of virtual rubles (called "cashless ruble", безналичный рубль) were used for inter-enterprise accounting and international settlement in the Comecon zone.
