1866 Octagonal 25 Cents. BG-708. Rarity-4+. Liberty Head. MS-66+ (NGC). <p><p><p><p>Crudely reeded edge and production appearance. Deep olive-gold color overall. The strike is quite bold and the eye appeal is sufficient unto the grade. Struck by Frontier & Co., active 1864-1872. Time was when small denomination California gold was an obscure specialty. Today in 2022 it is widely collected. <em>A Guide Book of United States Coins</em> has a listing of these by types and furnishes a nice introduction. This piece is the second finest thus far graded at NGC.<p>
