Based on the provided information, the value of a silver quarter depends on two primary factors: its silver content and its rarity as a collectible coin.
Generally, all Washington quarters minted for circulation in the year 1964 and earlier are composed of 90% silver. This intrinsic silver content gives them a baseline value that is significantly higher than their 25-cent face value, fluctuating with the daily market price of silver. Therefore, any U.S. quarter dated 1964 or before is worth money simply for its metallic composition.
Beyond the silver content, certain years, mint marks, and error varieties are considered key dates by collectors and are worth much more. These numismatic coins are valuable due to their low mintage numbers or specific die errors. The provided context highlights several of these particularly valuable Washington quarters, noting their value is often determined for coins in MS60 condition or better.
Examples of these highly sought-after silver quarters include the 1932-S, 1936-D, and 1932-D. The list also identifies several valuable error coins, such as the 1934 Doubled Die, the 1937 Doubled Die Obverse, the 1943-S Doubled Die Obverse, and the 1950 S over D variety. These specific coins can be worth hundreds or even thousands of dollars depending on their condition.
