Who designs new coins?

New coins are designed by artists that work for the U.S. Mint. They are called sculptor-engravers. The designs are reviewed by the Citizens Coinage Advisory Committee and the Commission of Fine Arts. The final decision on a new design is made by the Secretary of the Treasury.

Making Coins

The U.S. mint goes through the following steps when manufacturing coins:

  • Blanking – The first step is called blanking. Long strips of metal are run through a blanking press. The press cuts out blank coins from the press. The leftovers are recycled to be used again later.
  • Annealing – The blank coins then go through the annealing process. In this process, they are heated up and softened. Then they are washed and dried.
  • Upsetting – The next step is the upsetting mill. This process forms the raised rim around the edges of the coin.
  • Striking – Striking takes place in the coining press. The coining press strikes the coin on both sides with a great amount of pressure. It stamps the design of the coin right into the metal.
  • Inspecting – Now that the coin is made, it still needs to be inspected. Trained inspectors examine the coins to make sure they were made correctly.
  • Counting and Bagging – Next the coins are counted by a machine and placed into bags to be shipped to banks.
