Buying gold bars. Not all investment-quality gold is equal. Investors, who want to add the physical product that coincides with the price of gold, may refuse from gold coins at once. The latter often have an attractive design, historic value and less gold. But they cost more because of their numismatic value. In addition to the high value, gold coins sometimes distort the value of an investor’s portfolio. Some financiers need the collector’s items, and the rest want to possess ordinary gold bars, that are usually easy to hold long term and change into cash.
