1898 Liberty Head Nickel. Proof-67 Cameo (NGC).An excellent Superb Gem from the traditionally undervalued series of Cameo Proof Liberty nickels. High quality pieces that feature Cameo contrast are an infrequent offering, and they are far harder to locate than examples from the standard, non-Cameo grading category. This particular piece is silky white with deeply mirrored fields and frosty devices. The strike is strong, with fully formed ears of corn and a crisp V on the reverse. The addition of this example would significantly strengthen any collection.
