Collectible coins are numismatic items that are sought after for their historical significance, rarity, and condition. In the United States, the Washington Quarter is a notable series, minted for the first time in 1932 to commemorate the 200th anniversary of George Washington's birth. The 1940 Washington Quarter, specifically minted in San Francisco, is part of a series that includes both circulated and uncirculated coins, with certain mint marks adding to its collectible value. The San Francisco mint mark (S) is associated with a lower mintage and can increase the coin's desirability among collectors.
