The U.S. produces both one-dollar bills (paper currency) and one-dollar coins (metal currency), both worth exactly $1. Dollar coins include the Sacagawea dollar (golden color), Presidential dollars, and the older Susan B. Anthony dollar (silver color). Despite numerous attempts to popularize dollar coins, Americans overwhelmingly prefer dollar bills, so coins are rarely seen in circulation except in some transit systems, vending machines, and post offices. Dollar coins last much longer than paper bills (30+ years vs. 6-7 years) but are heavier to carry. Both are legal tender and accepted everywhere.
The quarter (25 cents) is special because it's the most widely used coin for transactions and vending machines in the United States. It equals 1/4 of a dollar, hence the name "quarter dollar." The quarter features George Washington and has been in continuous production since 1796. Since 1999, the U.S. Mint has produced special state quarters, national park quarters, and commemorative designs, making quarters highly collectible. Four quarters equal one dollar, and quarters are commonly used in laundromats, parking meters, and arcade games.
Standard U.S. coin rolls contain specific quantities: 50 pennies ($0.50), 40 nickels ($2.00), 50 dimes ($5.00), 40 quarters ($10.00), 20 half-dollars ($10.00), and 25 dollar coins ($25.00). These standard quantities are used by banks and the Federal Reserve. Coin rolls make it easier to count and transport large amounts of coins. You can purchase empty coin roll wrappers to organize your own coins or exchange rolled coins at most banks.
Modern U.S. coins are made of base metals, not precious metals like they once were. Pennies are 97.5% zinc with a thin copper plating (2.5%). Nickels are 75% copper and 25% nickel. Dimes, quarters, and half-dollars have a pure copper core with outer layers of copper-nickel (91.67% copper, 8.33% nickel overall). Dollar coins are manganese brass. The switch from silver coins happened in 1965 due to rising silver prices. Only pennies minted before 1982 were solid copper, making some old pennies worth more than face value for their metal content.
The penny, nickel, dime, and quarter are the circulating coins that we commonly use today.
