1852 Proof U.S. Assay Office Ten Dollar - Copper

Coin Details

Description

This is a copper proof from the dies of the 1852 U.S. Assay Office ten-dollar piece. Moffat & Co. dissolved early in 1852 and Curtis, Perry & Ward took over the Assay Office contract; Adams places every piece reading UNITED STATES ASSAY OFFICE OF GOLD SAN FRANCISCO CALIFORNIA under them. They struck fifty-dollar pieces dated 1852 at 887 and then 900 THOUS., the federal standard, after the Custom House refused the lower-fineness ingots, and ten- and twenty-dollar pieces in 1852 and 1853 at 884 or 900 THOUS. The office closed on December 14, 1853, and its premises became the San Francisco Branch Mint, which began work on April 15, 1854. NGC lists it as Kagin number 8 among the trial pieces. Catalogue number: K-8.
