United States Mint, Philadelphia: List of Coins Minted (Page 1 of 14)

The Philadelphia Mint was created from the need to establish a national identity and the needs of commerce in the United States. This led the Founding Fathers of the United States to make an establishment of a continental national mint a main priority after the ratification of the Constitution of the United States. The Coinage Act of 1792 was entered into law on April 2. It proclaimed the creation of the United States Mint. Philadelphia at that time was the nation's capital; therefore the first mint facility was built there. The Mint Act also instituted a decimal system based on a dollar unit; specified weights, metallic composition and fineness; and required each United States coin feature "an impression emblematic of liberty".

Initially, this was "the" mint of the United States. Over time, other branches were opened in other locations, and now the Philadelphia Mint is just a branch (albeit the most important one) of the U.S. Mint.

The Philadelphia Mint sometimes uses the letter P as a mint mark.

Being the first mint to start striking American coins, the Philadelphia Mint did not use a mint mark on its production.
