1938-D/S Buffalo Nickel. FS-511, OMM-001. MS-67+ (PCGS). CAC.While not attributed on the holder, this 1938-D/S is the FS-511 variety listed in the Guide Book. Far more pronounced, the FS-511 always commands a significant premium over the other dies. The present example is simply stunning: beautiful champagne, magenta, and indigo blend on its surfaces to add spectacular color, the strike is superb with full detail showing, marks are virtually nonexistent, and, as indicated by incredibly smooth and borderline mirrorlike fields, the dies used to strike this specimen were new.
