1871 Octagonal 25 Cents. BG-717. Rarity-3. Liberty Head. MS-68 (PCGS). A virtually perfect Ultra Gem from this scarce Octagonal variety. The surfaces are a pale sandy-gold hue and entirely undisturbed by blemishes. Rich frosty texture across the devices contrasts the more flashy reflectivity in the fields. This piece is the sole finest certified by PCGS and represents a significant find for Cal Frac specialists.
