Barber Quarters are a series of US coins designed by Charles E. Barber, minted from 1892 to 1916. The 1911 Denver Barber Quarter, with a mintmark 'D', is part of this series and features Lady Liberty on the obverse and an eagle on the reverse. It is sought after by collectors due to its historical significance and relatively limited mintage, especially in higher grades. The 25-cent denomination is commonly collected, and values can vary significantly based on condition and rarity.
