EXTREMELY FINE. AN EXCEPTIONALLY BEAUTIFUL LARGE-MARGINED EXAMPLE OF THE IMPERFORATE 1851 ONE-CENT TYPE Ia, GRADED XF 90 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).

From our 1978 Rarities sale and ex Dr. Amonette and Collier. With 1970, 1981, 1996 and 2011 P.F. certificates. With 2009 P.S.E. certificate (XF 90; SMQ $24,000.00)
