Patina consists of faint yellow, light amber, light blue, and turquoise blue. All of these colors blend together beautifully to create light metallic looking luster that is reminiscent of a headlight in some respects. Boldly struck up for the issue both sides compliment each other in a more than splendid manner and gorgeous eye-appeal is portrayed. Finest and only graded specimen at NGC as of 4/30/18.
