Gold has always been a symbol of affluence. Gold is one metal that can last for a long time. In fact, in case you cast a gold ring you can be certain that it would retain its form for approximately 1000 years if not more. Moreover, it is one of the few metals that could keep rust off. This means that no matter how careless you are in caring for gold, you can be sure that rust would not mar its glitter. That is exactly the reason why most of the financial institutions have kept gold coins for sale. You could even buy silver bars and coins. Gold and silver are real equity.
