1867 Silver Three-Cent Piece. Proof-66 Cameo (NGC).A wonderfully original example toned in rich charcoal gray patina. Direct lighting calls forth not only bold cameo contrast between the fields and devices, but also iridescent undertones of vivid golden-apricot, cobalt blue and pinkish-lilac. Fully struck, as befits the method of manufacture, and exceptionally well preserved in a survivor of this 625-piece Proof silver three-cent issue.
