Caption: Coins. International assortment of gold coins. The cost of the metal in a gold coin is often worth more than the coins nominal value. As a result, gold coins are often minted and sold only as collector's items. Many gold-coloured coins used in common circulation as small change are actually comprised of a cheap alloy rather than gold itself. Gold is rare, expensive, heavy and soft; for these reasons its main use is in jewellery and in monetary reserves. Gold has the chemical symbol Au.
