It means the coin was minted at Philadelphia. However, Philadelphia didn't use a mint mark on any coins made before 1979, except for the famous "war nickels" issued from 1942 to 1945. Starting in 1979, $1 coins gained the P mint mark. The following year all other Philadelphia coins except for cents also began using the P mint mark. Philadelphia cents continue to be struck without mint marks, for complex reasons having to do with special production at other mints when Philadelphia and Denver can't meet the demand for pennies.

The Philadelphia Mint does not display a mint mark on its pennies because Philadelphia is their primary mint location. Mint marks are typically used to distinguish coins minted in different locations. Pennies minted in Philadelphia simply do not include a mint mark.
