RUSSIA. 25 Kopeks, 1858-CNB OB. St. Petersburg Mint. Alexander II. NGC PROOF-65 Cameo. KM-C-166.1; Bit-56. A staggering and wholly captivating Gem, this vibrant proof minor yields a light steely gray nature with ample frosting imparted to the devices, along with a rich, mirrored brilliance in the fields. As such, the resulting cameo effect is rather extraordinary, with a delightful champagne hue sprinkled throughout, augmenting its beauty that much further. From the Sigma Collection.
