A Dollar Coin is a type of currency that is worth one United States dollar. Unlike paper money, which is made from cotton and linen, dollar coins are typically made from metal, making them more durable and longer-lasting. The U.S. Mint produces these coins, and they often feature notable figures or symbols from American history. Dollar coins have been issued in various designs over the years, including the Susan B. Anthony coin and the Sacagawea coin. While they are legal tender, dollar coins are less commonly used in everyday transactions compared to paper bills, leading to lower circulation and public familiarity.
