The coin in question is a 1909 Barber Quarter, part of the renowned Barber coinage series. Struck at the Philadelphia Mint, this quarter features a classic design by engraver Charles E. Barber. Made of silver, it weighs 6.25 grams and has a diameter of 24.3 millimeters, typical measurements for U.S. quarters of this era. The Barber Quarter serves as a notable representation of early 20th-century American coinage. With a production of 9,268,000 pieces, the 1909 Barber Quarter is not exceptionally rare; however, its condition can significantly influence its market value. As a collector's item, this quarter maintains a strong interest among numismatists, particularly due to its historical relevance and the artistry of its design. Being a U.S. quarter, it has a face value of 25 cents, but collectors often seek it out for its silver content and historical significance rather than its spending value. The "P" mint mark denotes its Philadelphia origin, a hallmark of quality in American coin production. Overall, the 1909 Barber Quarter is an excellent addition to any collection, embodying both charm and the legacy of American currency.
