The mint reopened as an assay office in 1876. Its machinery was evidently damaged during the war, but because of its importance, unlike the mints at Charlotte and Dahlonega, in 1877 U.S. Mint agent James R. Snowden asked the superintendent of the office, Dr. M. F. Bonzano, to report on the condition of the facility for minting. Upon receipt of Bonzano's report, new minting equipment was shipped to New Orleans. The building was refurbished and put back into active minting service in 1879, producing mainly silver coinage, including the famed Morgan silver dollar from 1879 to 1904.
