RUSSIA. 5 Rubles, 1827-CNB NA. St. Petersburg Mint. Nicholas I. NGC AU-58. Fr-154; KM-C-174; Bit-2; Sev-402; Uzd-202. The single second finest certified of the date on the NGC population report, one finer (MS 61). An <strong>EXTREMELY</strong> <strong>RARE</strong> date and the key to the series with an unknown mintage, this handsome survivor exhibits semi-prooflike luster in the protected areas offering much flash and reflectivity, while the open fields are a bit more subdued. Upon inspection the surfaces show light signs of handling consistent for the grade with minor marks and abrasions adding a bit of character to this wholesome piece. Seldom are examples of this date encountered, auctions records indicate only fourteen appearances of different pieces since 1910. The chance to acquire such an awesome rarity occurs infrequently and should be given serious consideration from advanced collectors.
