Barber Quarters are a series of coins minted in the United States from 1892 to 1916, designed by Charles E. Barber. The 1913 Barber Quarter, particularly those minted in San Francisco (S mint mark), is sought after by collectors due to its limited production and historical significance. These coins feature an obverse design of Liberty with a phrygian cap and an intricate reverse design showcasing an eagle, making them notable examples in American numismatic history. The 25 cents denomination, known as a quarter, is a popular collectible, with certain years and mint marks commanding higher premiums due to their rarity and condition.
