Philadelphia

Philadelphia was the only mint in operation in those earliest years, and identification of the coinage was not necessary.  The practice was continued even after the branch mints were established.  In 1942, however, when World War II restrictions upon the use of metal made a change in the 5-cent piece necessary, a substitute alloy composed of 35% silver, 56% copper and 9% manganese was adopted.  In order to more easily distinguish between the regular copper-nickel alloy and the substitute composition, the mint mark was moved from its usual position at the right of Monticello and placed above the dome of the building on the wartime 5-cent piece.  The letter “P” appeared for the first time on Philadelphia coinage.  After the war, when a return to the regular alloy was made, the mint mark was restored to its former position and the letter “P” on Philadelphia coinage was discontinued.

In July of 1979, the Susan B. Anthony dollar coin was introduced, replacing the standard 1 1/2 -inch coin.  Once again, the “P” mint mark was placed on Philadelphia production, this time on the dollar denomination
