Description
The 2005 (S) Proof Kansas 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 3.3 million examples, making this ranked 18th of 33 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 features an American bison and a sunflower, the state animal and state flower. The bison recalls the millions that once roamed the Kansas prairies, while the sunflower continues to blanket Kansas fields each autumn. California, Minnesota, Oregon, Kansas, and West Virginia. Satin finish specimens from mint sets were produced. 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.
