The US has 4 Mints and all of them strike pennies (cents, actually).
Effectively all circulating cents are made at the mints in Philadelphia (no mint mark on that denomination) and at Denver (a "D" under the date).
The San Francisco mint ("S") strikes proof coins for sale to collectors, but they haven't made any circulating cents since 1974.
The West Point mint normally only makes bullion and commemorative coins, but when demand for cents is extremely high they sometimes will make circulating cents as well. These coins don't have a "W" mint mark, though, so they look just like Philadelphia cents - there's no way to tell them apart.
In 2011, the U.S. Mint produced 4,938,540,000 pennies.
