Description
The 2003 (S) Proof Missouri State Quarter is a proof quarter struck at the San Francisco Mint, part of the State Quarters 1999-2008 series. The U.S. Mint produced 3.4 million examples, making this ranked 6th of 20 mint variants by mintage, with less than 1% 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 shows Lewis and Clark in a canoe on the Missouri River with the Gateway Arch rising before them and the inscription "Corps of Discovery 1804–2004." Missouri was the launching point for the Lewis and Clark Expedition and the gateway to the American West. Illinois, Alabama, Maine, Missouri, and Arkansas. Some state designs attracted controversy over their selections. As a proof issue, this coin was struck multiple times on specially prepared polished planchets using polished dies, producing mirror-like fields and frosted design elements prized by collectors. Struck at the San Francisco Mint, established during the California Gold Rush and now primarily producing proof and collector coins. Estimated market value ranges from $0 to $25 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 #913043.
