EXTREMELY FINE GEM. A SUPERB EXAMPLE OF THE ONE-CENT 1861 ISSUE IN THE DARK BLUE COLOR. THIS IS ONE OF THE SCARCEST SHADES OF THE ONE-CENT.
Don Evans notes in his book on the 1c 1861 Issue (p. 33) that the Dark Blue shade is very close to Indigo shade used for the "Premiere Gravure" (Scott No. 55) and in fact he believed that this should be the formal designated color name for this shade.
With 1992 P.F. and 2006 P.S.E. certificates (XF-Superb 95; SMQ $3,850.00). This is the highest grade awarded and no other examples have achieved this grade
