Barber Quarters are a series of coins produced by the United States Mint from 1892 to 1916, designed by sculptor Charles E. Barber. The 1900 Barber Quarter minted at the San Francisco Mint (S) is particularly sought after by collectors. The coin's design features a profile of Liberty on the obverse and an eagle with shield on the reverse. San Francisco mintages are often lower than those from other mints, contributing to their rarity and value in the numismatic market.
