US Coins minted before 1979-1981 (the exact date varies with the coin) don't necessarily have a mint mark. Coins without a mint mark were minted at the US Mint facility in Philadelphia. Since 1981, all coins except for the US cent will have a mint mark; for Philadelphia it will be a "P". US cents, often misnamed "pennies," minted in Philadelphia still do not carry a mint mark even through 2007.
