1877 Shield Nickel. Proof-67 (PCGS).;A truly exquisite Superb Gem, this is one of the finest certified survivors of the popular Proof-only 1877 nickel. Brilliant with satiny devices and modestly mirrored fields, the eye appeal is nothing short of strong. With a full strike and virtually pristine features, as well, this coin would do justice to the finest Shield nickel collection on the PCGS Set Registry.
