Collectible coins encompass a wide range of numismatic items that hold value for their rarity, historical significance, or artistic design. The United States quarter, specifically the 25-cent denomination, includes various series, such as the Barber Quarters minted from 1892 to 1916. The 1909 Barber Quarter, particularly those struck at the San Francisco Mint, is of notable interest to collectors due to its limited mintage and the popularity of the Barber series within American numismatics.
