Where does the money come from?

All U.S. currency comes from the Treasury Department. However there are two entirely separate branches for coins and paper money.

The U.S. Mint manufactures coins. There are currently 4 mints:

> Philadelphia ("P" mint mark on coins after 1980)

> Denver ("D")

> San Francisco ("S", only on proof and collectors' coins)

> West Point ("W", only on bullion and collectors' coins)

Bills are printed by the Bureau of Engraving and Printing, the same department that makes postage stamps. There are two facilities, one in Washington DC and the other in Fort Worth.
