Description

The 1999 (P) Pennsylvania State Quarter, struck at the Philadelphia Mint, is part of the State Quarters 1999-2008 collection. The Philadelphia Mint struck 349,000,000 Pennsylvania quarters dated 1999. The obverse features George Washington facing left, based on a 1786 bust by Jean-Antoine Houdon and the reverse displays unique designs representing each of the 50 U.S. states, released in the order the states ratified the Constitution or joined the Union. The reverse features the Commonwealth statue from atop the State Capitol dome, a keystone representing Pennsylvania's nickname "The Keystone State," and the state motto "Virtue Liberty Independence." These elements honor Pennsylvania's central role in the founding of the nation. The program's first five quarters, issued in 1999, honored in release order Delaware, Pennsylvania, New Jersey, Georgia, and Connecticut. The program instantly became the most successful numismatic initiative in U.S. history. Estimated market value ranges from $0.25 to $6 depending on grade and condition. Struck in 75% copper, 25% nickel, weighing 5.67 grams, 24.3 mm in diameter, with a reeded edge. Cataloged as PCGS #5946.
