The New Orleans Mint (O mint mark) will close at the beginning of the Civil War (1861) and will not reopen until the end of Reconstruction in 1879. During its two stints as a minting facility, it will produce both gold and silver coinage in eleven different denominations, though only ten denominations will ever be minted there at one time (in 1851 silver three-cent pieces, half dimes, dimes, quarters, half dollars, and gold dollars, Quarter Eagles, half eagles, eagles, and double eagles).
