Annual Report of the Director of the Mint for the Fiscal Year Ending June 30, 1863
U.S. Mint Annual Reports (1863)
Mint Director James Pollock's report for the fiscal year ending June 30, 1863.
Paul Hybert summary: "The coinage is reduced for another year, and for the same reasons. A branch mint opens at Denver, Colorado Territory, but processes only bullion to date. Although the small cent is more popular than the discontinued large cent, the inclusion of nickel to give it an intrinsic value closer to one cent provides no benefit and should be discontinued."
