As investment vehicles, gold bars are gaining in popularity primarily because gold bars carry much lower premiums than gold bullion coins carry. For example, premiums on kilo gold barscan be as much as $50 per ounce lower than the premium on American Gold Eagles. Truly, gold bars are an exciting way to invest in gold. Hefting large gold bars almost causes an adrenalin rush. Invariably, people holding large gold bars for the first time ask, "How can something so small be so heavy?" A huge amount of wealth can be stored and concealed in gold bars.
