U.S. Mint Reports (1827)
Periodical Summary
A report from the Director of the Mint (Samuel Moore) on the assay of foreign coins. The same text appears in the American State Papers, finance (class 3), volume 5, no. 767.
Paul Hybert summary: "As requested by a resolution of the Senate, a detailed assay of foreign coins, from mint director Samuel Moore to Treasury Secretary Rush, to President Adams, who relayed it to Congress. Evidently the summary, as presented in no. 748 [the Mint Director's assay report, February 7, 1826], did not go over well with Congress, who expected a level of details as found in earlier assay reports. Pure copper is found to be the common alloy in silver coins, while the alloy for gold coins is some combination of copper and silver. Although some mints use a constant ratio between the copper and silver in their gold coinage, other mints do not; the U.S. uses an alloy with equal parts of copper and silver to obtain a pleasing consistent color for the gold coins."
