1c Blue, Ty. Ia (6). Position 92R4, large bottom margin beautifully showing the complete characteristics of the type, other sides full to clear, rich color, two neat penstroke cancels leave design clearly visible, light horizontal crease at top, tiny surface scuff at top left is barely detectable

VERY FINE APPEARING EXAMPLE OF THE 1851 ONE-CENT TYPE Ia IMPERFORATE.

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).

2007 P.F. certificate no longer accompanies (scan from PF website is included). Scott value is for pen cancel, though considering the fact that a light pen cancel leaves the design characteristics unmasked, the reduced Scott value seems unjustified here.
