A coin is a piece of metal, usually disc-shaped, which bears lettering, designs or numbers showing its value. Until the eighteenth and nineteenth centuries coins were given monetary worth based on the exact amount of metal contained in them, but most modern coins are based on face value, the value that governments choose to give them, irrespective of the actual metal content. Coins have been made of gold (Au), silver (Ag), copper (Cu), aluminum (Al), nickel (Ni), plastic and in China even from pressed leaves. Gold proves to be the most popular. Since civilization began gold has been regarded as a symbol of power and wealth. In many societies gold was seen as a magic substance, which could protect people against illness or evil spirits.
