Factors That Influence the Value

Rarity and Errors of the 1950-D/S Washington Quarter
Collectors are drawn to the 1950-D/S Washington Quarter not only for its historical significance and unique minting characteristics but also for its prominent varieties and errors. These imperfections make the coin particularly sought-after, attracting both enthusiasts and investors looking to diversify their collections.
Known Errors and Varieties
- Repunched Mint Mark (RPM) The term RPM refers to coins where the mint mark was struck more than once, often at different angles or slightly shifted, resulting in a doubled-image effect. This error was not uncommon during the early 1950s due to manual mint mark applications. Estimated value ranges from $40 – $120, and rarity level is considered “Uncommon.”

Clipped Planchet Occurring when the coin blank (planchet) is improperly cut, a clipped planchet error results in a crescent or more elliptical edge. The rarity of clipped planchet errors on 1950-D/S quarters makes them particularly attractive with retail values hovering around $80 – $150. Rarity level: “Rare.”
Die Crack Caused by cracks in the mint die itself, die crack errors on the 1950-D/S feature notable lines or raised patterns across the coin’s surface. These can occur on the obverse or reverse, sometimes dramatically altering its appearance. Values can range from $50 – $200, dependent on extent and location of the crack, with rarity level “Uncommon.”

- Double Die Obverse (DDO) A rarity in this mint’s production, the DDO error features a doubled image on the coin’s obverse. The error appears as a slight or pronounced doubling of Washington’s profile or inscriptions. Due to its eye-catching nature, examples can sell for $250 – $400+. Rarity level: “Very Rare.”
Price Impact Summary
Minor Errors: Typically contribute modestly to a coin’s value, making these coins appealing additions for collectors, though less attractive for resale.
Major Errors: Errors such as the Double Die Obverse significantly affect a coin’s monetary worth, standing out in auctions and often fetching premium prices.
Condition Impact: The higher the coin’s grade, the greater the value. Mint State errors can command significantly more than those in lower conditions due to their rarity and appeal.
Authentication: Reliable third-party verification by organizations like PCGS or NGC can significantly increase the value of coins exhibiting errors, providing buyers with the confidence that their investment is genuine.
