Barber Quarters are a series of coins minted in the United States from 1892 to 1916, featuring a design by engraver Charles E. Barber. The 1908 Barber Quarter, minted in San Francisco, is particularly noteworthy as it is one of the lesser-produced years, contributing to its collectible value. This quarter contains 90% silver and 10% copper, and its design reflects the Liberty head on the obverse and a heraldic eagle on the reverse. Collectors often seek out specific mint marks, such as the "S" for San Francisco, which can affect the coin's rarity and market value.
