Anthony dollar coin. Note also that no US coins minted in 1965 through 1967 had mintmarks, regardless of where they were produced..

The US Gold Dollar was minted from 1849 to 1889. No US Gold Dollars have been issued since 1889. From 1849 to 1854 the head on the coin represented Liberty. From 1855 to 1889, the head on the coin was a representation of an Native American (then called an Indian). US Dollar coins currently in circulation are neither gold nor silver, but a variety of alloys, some of which look like gold. They include coins representing: * Susan B. Anthony (minted 1979-1981,1999) in a copper-nickel alloy, * Sacagawea (minted 2000-present) in copper with manganese brass cladding, * deceased Presidents of the United States (2007-present) in copper with manganese brass cladding, * Sacagawea , Native American Series, (minted January 2009-present), in copper with manganese brass cladding.

US coins minted before 1979-1981 (the exact date varies with the coin) don't necessarily have a mint mark. Coins without a mint mark were minted at the US Mint facility in Philadelphia. Since 1981, all coins except for the US cent will have a mint mark; for Philadelphia it will be a "P". US cents, often misnamed "pennies," minted in Philadelphia still do not carry a mint mark even through 2007.
