1999-S Pennsylvania State Quarter Gem Proof
The 1999-S Pennsylvania quarter represents a key moment in modern American coinage, issued as part of the celebrated 50 State Quarters Program. Struck at the San Francisco Mint, this coin features a Gem Proof finish, showcasing sharp details and highly polished surfaces that bring its intricate design elements to life. The obverse displays the classic left-facing portrait of George Washington, originally designed by John Flanagan. Legible inscriptions on this side include the words LIBERTY and IN GOD WE TRUST, along with the denomination of QUARTER DOLLAR and the distinctive S mint mark. On the reverse, designed by John Mercanti, the coin celebrates the state of Pennsylvania. The design features an outline of the state itself, with the Commonwealth statue positioned on the left and a keystone placed to the right. The state's guiding motto, VIRTUE, LIBERTY, INDEPENDENCE, is inscribed across the center, while the year of issue, 1999, and the national motto, E PLURIBUS UNUM, anchor the bottom.
