The US Mint doesn't promote fresh breath, but it does make a pretty penny. Its primary mission is to produce an adequate volume of circulating coinage for the nation to conduct its trade and commerce. The Mint distributes coins and paper money to the Federal Reserve banks and branches, maintains custody of the Nation's gold and silver assets (worth more than $100 billion), and redeems and processes mutilated coins. It generates more than $1 billion in annual revenue by selling proof and uncirculated coins; commemorative medals; and platinum, gold, and silver bullion coins to the public. Despite its standing as a government institution, the US Mint does turn a profit, which it transfers to the US Treasury.
The United States Mint operates six facilities across the United States, located in Washington, DC; Philadelphia; West Point, New York; Fort Knox, Kentucky; Denver; and San Francisco.
