Additional Information
Mint Sources of Silver
A retrospective commentary in the Annual Report of the Director of the Mint, 1867 (sic), noted, that the fiscal year ended June 30, 1860 represented the first time that Nevada silver had been deposited in any of the United States mints, during which year $102,540.57 worth was paid in. Much must have come from the Comstock Lode.
Prior to this, the main source of domestic silver had been in parting the metal from gold, rather than from specific silver deposits. It was not until fiscal year 1858 that silver deposits on their own came from elsewhere, during which year $15,623 was deposited in the mints from the Lake Superior district, followed in 1859 by $30,122.13 from the same source. 1859 also saw the first deposits of silver from North Carolina, amounting to $23,398.
1860, the first year of the Nevada silver deposit, was also the first year of deposit of silver from Arizona, ($135,357) and New Mexico ($1,200). This does not include silver parted from gold in any of these regions.
