The Mint contains 91.67% of gold, but it costs more than pure gold bars because of its value as a collector's item. If you want to invest in gold bars or increase your existing stocks, gold bars can be one of the most cost-effective ways to get more total ounces of gold for your investment money. Physical gold suitable for investment, also called gold ingots, can be purchased at the spot price, which is the price of gold without manufacturing plus additional costs, which vary depending on the seller. Additionally, you can rollover your 401k to a Gold IRA Account to further diversify your portfolio and take advantage of the potential benefits of investing in gold.
