U.S. coins are the currency used in the United States, produced by the U.S. Mint. They come in various denominations, including pennies, nickels, dimes, quarters, and half dollars. Each coin features unique designs that often represent important historical figures, symbols, or events in American history. Coins are made from different metals, such as copper, nickel, and zinc, which give them distinct colors and weights. They are used for everyday transactions and are an essential part of the U.S. economy. Coins can also be collected as numismatic items, with some rare coins being highly valuable.
