A more thorough explanation:

The Bureau of the Mint, also known as the United States Mint, is a part of the U.S. Department of the Treasury. Its main responsibility is to produce coins that are used in trade and commerce, as well as numismatic coins, gold and silver coins, and national medals.

For example, the Bureau of the Mint produces the coins that we use every day, such as pennies, nickels, dimes, and quarters. They also produce special coins, like the commemorative quarters that feature different states and national parks. Additionally, the Bureau of the Mint is responsible for producing gold and silver coins, like the American Eagle and the American Buffalo.

The Bureau of the Mint also operates the gold-storage facility at Fort Knox, Kentucky. This facility stores a large amount of gold that belongs to the U.S. government.

In summary, the Bureau of the Mint is responsible for producing coins and medals, as well as storing gold for the U.S. government.
