Since 1986, the United States Mint has struck gold bullion coins expressly for collectors and investors with an interest in holding precious metal. Two major types are available, both of which Morgan Gold recommends as fungible gold bullion coins:
- American Eagle Gold Bullion Coins: Utilizing the classic obverse design of the Saint-Gaudens Double Eagle, the Gold Eagle debuted in 1986 and remains in production as of 2010. Examples are issued yearly in Tenth-Ounce, Quarter-Ounce, Half-Ounce and One-Ounce sizes.
- American Buffalo .9999 Fine Gold Bullion Coins: Containing a higher fineness rating than the Gold Eagle, the Gold Buffalo introduced in 2006 also enjoys strong demand among collectors and investors. Most examples are issued in One-Ounce format.
