The gold bar price of course changes daily with the price of gold. As the value of gold increases so the value of the gold bar increases.
Large gold bars are a useful safe haven for storing assets for the long term in economic uncertainty, while the smaller gold bars can be easily bought, stored, transported and sold for the short term.
Buy the highest gold bar weight if affordable as will pay less premium per ounce or gram that way. As the gold bar price goes up, the premium per ounce/gram decreases also.
The premium, cost pay over spot gold is made up of, the manufacturing costs, the gold bar dealers costs, shipping, insurance costs and etc.
It is recommended to buy smaller gold bars, if needed to sell some of the gold bars from time to time to cover unexpected expenses.
Unless absolutely have to, we recommend do not sell gold bars for national fiat currency as the value of fiat currency (paper money) is deteriorating rapidly.
