In the early 19th century, New Orleans, which was the fifth-largest city in the United States until the Civil War, conducted more foreign trade than any other city in the nation. It was also located relatively near to gold deposits recently discovered in Alabama. While the Philadelphia Mint produced a substantial quantity of coinage, in the early 19th century it could not disperse the money swiftly to the far regions of the new nation, particularly the South and West. In contrast to the other two Southern branch mints, which only minted gold coinage, the New Orleans Mint produced both gold and silver coins, and in much greater quantities and total value, which marked it as the most important branch mint in the country until the San Francisco Mint began minting a large monetary value of gold coins in the mid 1850s.
