10c Dark Green (68a).
Original gum, lightly hinged, beautiful rich color and intense shade, sharp
impression, choice centering with extra wide marginsEXTREMELY FINE GEM. A SUPERB ORIGINAL-GUM EXAMPLE OF THE 10-CENT 1861 ISSUE -- FAR RARER IN THIS CONDITION THAN THE SCOTT VALUE WOULD SUGGEST.
The increased awareness of the rarity of 1847 to 1879 issues in superb original-gum condition has elevated many valuations for stamps with modest Scott values. The 1861-66 Issues are prime examples of this trend. This 10c 1861 has a Scott value of $900, yet one would be hard-pressed to locate more than a few examples with original gum, choice centering and rich color -- the characteristics that make this stamp so extraordinary.

Knowledgeable collectors recognize and appreciate the great rarity of well-centered, original gum classics. In particular, the 1861-66 Issue has been "discovered" as one of the most challenging of all. As recent auction realizations show, collectors ignore Scott values in pursuing these elusive examples.
