Every coin made in Charlotte carries an identifying mark—the letter “C.” The coins, produced here at the Charlotte branch of the United States Mint from 1837 to 1861, are rare. They include a $5 coin called a half-eagle, a $2.50 coin called a quarter eagle, and a $1 coin. The Mint Museum Randolph, housed in the old Mint building, has a few of the coins on display in its Heritage Gallery.
