Gold discoveries in the Appalachian Mountains of North Carolina triggered America's first gold rush in the early 19th century. By 1830, it was risky and expensive to ship gold to Philadelphia for assay and sale. The U.S. Mint at Charlotte opened in 1838. Gold coins only would be struck there until May 1861, when North Carolina seceded from the Union. The Mint was officially closed in 1861; never to re-open. All Charlotte gold coins are highly desired by collectors and investors for their history and rarity.
