The branch Mint established in 1838 in New Orleans, Louisiana. It struck coins for the United States until its seizure in 1861 by the Confederacy. (Some 1861-O half-dollars were struck after the seizure.) It reopened in 1879 and struck coins until 1909 (actually closed in 1910). Now this facility is a museum. More information on mintmarks.
