History Timeline

The Mint has a fascinating history. Check out this short video to learn about us and what we do!

It’s the 18th century, and the colonies are breaking free from England. A new country! But what about money? How can they pay for their war against England?

Colonists already used lots of currencies. But if the colonies win, should they use British pounds after the war? Spanish milled dollars? …Or invent a whole new currency?

Congress set the other coins’ values to the Spanish milled dollar. Jefferson says that should be our new nation’s money, but divided into 100 parts. In 1785, Congress invents a new dollar currency and decides which metals the coins will be made from. Now they just need someone to make them!

Congress passes the Coinage Act, creating a national mint to make gold, silver, and copper coins. The United States Mint is born!

President George Washington appoints David Rittenhouse, a leading scientist, as the first Director of the Mint. Construction begins on a building in Philadelphia, the nation's capital at the time.

The new Mint building opens in Philadelphia and coins are made: silver half dimes and copper cents. The silver probably comes from someone’s silverware (maybe George and Martha Washington’s). Harnessed horses power the coin-stamping machines.

A security system is installed: a watchdog costing $3.

America’s first "gold rush" begins in North Carolina.

Gold is discovered in Georgia, spreading gold rush fever further south.

The Mint moves to a second location in Philadelphia.

The first steam-powered coin press is put in place. Coins are made faster (about 100 coins per minute) with the steam press than with the old horse- and man-powered coin presses.

Three new Mint branches open in:

  • Charlotte, North Carolina and Dahlonega, Georgia, close to gold mines. Both Mint locations make gold coins.
  • New Orleans, Louisiana, the location of a large port. The New Orleans Mint makes both gold and silver coins.

Gold is found in California.

The California Gold Rush takes off the following year.
