The Seated Liberty Quarter, designed by engraver Christian Gobrecht, was minted from 1838 to 1891 and features Lady Liberty seated on a rock, holding a shield and a liberty cap. The 1866 Philadelphia mint issue is particularly notable among collectors, as it marks the year when the design was produced with no motto on the reverse, distinguishing it from later issues with the motto "In God We Trust." These quarters are highly sought after for their historical significance and aesthetic appeal, representing an important era in United States coinage. The coin typically has a diameter of 24.26 mm and a composition of 90% silver and 10% copper.
