A large coin moves gold through a growing nation

Congress authorized the double eagle in 1849 as California gold changed the scale of American bullion flows.

New Orleans and San Francisco issues, Civil War finance, the 1866 motto, and the 1877 denomination spelling create three major chapters beneath Longacre's portrait.
