The following is a list of United States mints, past and present:
| Location | Years of operation | Mint mark | Notes |
|---|---|---|---|
| Philadelphia, Pennsylvania | 1793– | P or none | Pennies and other coins struck prior to 1980 do not carry Philadelphia mint marks, except for Susan B. Anthony dollars and wartime Jefferson nickels. Although the mint officially opened in 1792, no regular issue coins were struck until 1793. |
| Charlotte, North Carolina | 1838–1861 | C | gold coins only |
| Dahlonega, Georgia | 1838–1861 | D | gold coins only |
| New Orleans, Louisiana | 1838–1909 | O | There was a long break in production from the beginning of the Civil War (1861) until the end of Reconstruction (1879). |
| Carson City, Nevada | 1870–1893 | CC | |
| San Francisco, California | 1854– | S or none | Since 1975, strikes only proof coinage, except for the Susan B. Anthony dollar. |
| Denver, Colorado | 1906– | D | |
| West Point, New York | 1973– | W or none | Commemorative coins bear the W mint mark; circulating coins are indistinguishable from coinage struck in Philadelphia. |
| Manila, Philippines | 1920–1922 1925-1941 |
M or none | The first (and to date only) U.S. branch mint located outside the Continental United States. Produced coinage in centavo denominations for Philippines circulation. |
Between 1965–1967 all U.S. coins were struck without mint marks. As it was clear from Gresham's law that the rising cost of silver (and the ensuing removal of most silver from coinage in 1965) led to hoarding or even melting of silver-based pre-1965 coins, overzealous collection of specific mint marks of those years by numismatists almost certainly would have exacerbated those shortages.
Pioneer coinage, tokens, private issue coins and paper money do not have official mint marks.
Famous quotes containing the words historical, united and/or states:
“This seems a long while ago, and yet it happened since Milton wrote his Paradise Lost. But its antiquity is not the less great for that, for we do not regulate our historical time by the English standard, nor did the English by the Roman, nor the Roman by the Greek.... From this September afternoon, and from between these now cultivated shores, those times seemed more remote than the dark ages.”
—Henry David Thoreau (1817–1862)
“I do not know that the United States can save civilization but at least by our example we can make people think and give them the opportunity of saving themselves. The trouble is that the people of Germany, Italy and Japan are not given the privilege of thinking.”
—Franklin D. Roosevelt (1882–1945)
“We cannot feel strongly toward the totally unlike because it is unimaginable, unrealizable; nor yet toward the wholly like because it is stale—identity must always be dull company. The power of other natures over us lies in a stimulating difference which causes excitement and opens communication, in ideas similar to our own but not identical, in states of mind attainable but not actual.”
—Charles Horton Cooley (1864–1929)
