Description

The 2020 (S) Proof Weir Farm National Historic Site Quarter is a proof quarter struck at the San Francisco Mint, part of the America the Beautiful Quarters 2010-2021 series. The obverse features George Washington facing left, based on a 1786 bust by Jean-Antoine Houdon and the reverse displays unique designs featuring national parks and sites from each state and territory. The reverse depicts an artist painting en plein air outside Julian Alden Weir's studio. Weir Farm is the only national park dedicated to American painting, preserving the studios where artists have found inspiration for over 130 years. National Park of American Samoa (AS), Weir Farm (CT), Salt River Bay (VI), Marsh-Billings-Rockefeller (VT), and Tallgrass Prairie (KS) were featured. The final full year of the program, with pandemic-related production adjustments. 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 $0.25 to $28 depending on grade and condition. Struck in 75% copper, 25% nickel over a pure copper center, weighing 5.67 grams, 24.3 mm in diameter, with a reeded edge. Cataloged as PCGS #811829.
