Description

A quarter from the Denver Mint, the 1999 (D) Pennsylvania State Quarter belongs to the State Quarters 1999-2008 series. The U.S. Mint produced 358.3 million examples, making this ranked 3rd of 10 mint variants by mintage, with 8% of production. 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 of statehood ratification. 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. Inaugural year featuring Delaware, Pennsylvania, New Jersey, Georgia, and Connecticut. The program instantly became the most successful numismatic initiative in U.S. history. Coined at Denver's facility, which transitioned from processing Colorado gold rush metal to full-scale coin production in 1906. Estimated market value ranges from $0 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 #5947.
