Barber Quarters are a series of U.S. twenty-five-cent coins designed by Charles E. Barber, minted from 1892 to 1916. The 1906 Barber Quarter specifically from the Denver Mint (marked with a "D") is part of this series and is known for its classic design featuring Liberty on the obverse and an eagle with a shield on the reverse. Collectors often seek out Barber Quarters for their historical significance and varying levels of rarity, particularly in uncirculated or high-grade conditions.
