拍品描述： C-168.1, Bit-229. One of only half a dozen at NGC to receive the highly coveted prooflike designation for the date. Struck from fresh dies with every last detail transferred from die to planchet, and then meticulously preserved afterward. Fully original surfaces with a mixture of olive, gunmetal blue and deep amber toning bringing the coin to life. A terrific example of the type from late in the reign of Tsar Nicholas I.，NGC MS-61 PL.，
