Alexander I gold 5 Roubles 1818 СПБ-MФ XF Details (Bent, Cleaned) NGC, St. Petersburg mint, Bitkin-19, Fr-150. Obv. Crowned double-headed Imperial eagle, with wings down, and date below. Rev. Crowned four-line inscription in wreath. Well struck, and possibly removed from jewelry in the past. The cleaning is not egregious, as the surfaces have re-toned nicely, but the edges show the possible effects of removal on close examination.
