1c Blue, Ty. Ia (6). Position 99L4, large even margins all around which go well beyond the bottom plumes, face-free cancel leaves the entire design clearly visible, deep rich color and proof-like impression on bright paper

EXTREMELY FINE GEM. A SUPERB USED EXAMPLE OF THE IMPERFORATE 1851 ONE-CENT TYPE Ia. THIS RARE AND REMARKABLE CLASSIC STAMP HAS BEEN GRADED XF-SUPERB 95 BY P.S.E.

Stamps printed from Plate 4 were issued in April, May and briefly in June 1857 before perforations were introduced. The relatively small number of imperforate Plate 4 stamps issued during this period explains the rarity and desirability of any of the imperforate stamp types produced from this plate (Ia, Ic, II, III and IIIa). The extremely rare Type Ia, showing the full design at bottom, was furnished only by 18 of the 200 subjects on Plate 4 (the remaining two bottom-row positions were sub-type Ic).

With 2008 P.S.E. certificate (XF-Superb 95; SMQ $49,900.00). This is the only example to achieve this grade to date and only one has graded higher.
