The 1958-P Washington Silver Quarter is a notable coin struck at the Philadelphia Mint, containing 90% silver and 10% copper. It weighs 6.25 grams with a diameter of 24.3 mm, featuring John Flanagan’s iconic portrait of George Washington on the obverse and a heraldic eagle on the reverse. The 1958 Philadelphia Mint struck about 6,360,000 quarters, making it relatively scarce compared to other years due to lower mintage.

“Blue Confetti Toning” on the 1958-P quarter refers to a specific type of attractive natural toning characterized by small, scattered blue spots or flecks resembling confetti. This toning develops over time as the silver surface reacts with sulfur compounds or other chemicals in the environment, often intensified by storage in albums or holders. The blue confetti adds a unique, colorful accent to the traditional silver-gray surface, enhancing the coin’s eye appeal.

Coins with such toning in brilliant uncirculated (BU) condition are highly desirable among collectors, as they combine excellent strike quality with aesthetic beauty. The toning is considered a positive attribute when evenly distributed and free from damage, increasing the coin’s value beyond its base silver content and standard condition.

Market values for the 1958-P Washington Silver Quarter in uncirculated condition typically range from $12 to $25 or more, depending on grade and overall eye appeal. Coins exhibiting eye-catching, vivid blue confetti toning can command premiums, with prices occasionally reaching $50 or higher if graded highly by professional services like PCGS or NGC.

In summary, the 1958-P Washington Silver Quarter with blue confetti toning is an attractive and collectible coin. Its combination of historical silver content, relatively low mintage, and distinctive natural blue toning makes it a prized addition to silver quarter collections or coins with vivid natural colorations.
