VERY FINE. A FRESH AND CHOICE ORIGINAL-GUM EXAMPLE OF THE 1866 15-CENT LINCOLN.
The 1866 15c Lincoln, which is regarded by many as the first U.S. commemorative stamp -- issued exactly one year after Lincoln's death -- is an exceedingly difficult issue to find in sound condition with original gum and choice centering. The statistics bear this out as only one original-gum example has been graded higher than F-VF 75 by P.S.E. -- a single hinged stamp graded XF 90.
With 2014 P.S.E. certificate
