A coin is “a piece of metal stamped and issued by the authority of a government for use as money” (dictionary.com). The word coin has its roots in the Latin word “cuneus,” meaning wedge. Coins have been in use since ancient times as early as 700 BC in China and Greece and 600 BC in India. In India, early coins were made of silver bars and were irregularly shaped because they had to be manually cut. Now a days coins are minted and are uniform. Wear these old Indian coins as charms and relive your childhood days.
