EXTREMELY FINE. A MAGNIFICENT TRANSATLANTIC COVER TO SWITZERLAND, CARRIED OUTSIDE THE MAILS FROM CHARLESTON TO NEW YORK, THEN BY BRITISH PACKET. THE FRANKING INCLUDES AN EXTREMELY RARE 1851 ONE-CENT PAIR FROM THE TOP ROW OF PLATE ONE EARLY, COMPRISING THE RARE TYPE Ib FROM POSITION 9R1E AND POSITION 10R1E, THE ONLY TYPE II POSITION ON PLATE ONE EARLY WITH THE COMPLETE DESIGN AT TOP.
Type Ib was produced only as an imperforate stamp. Six positions on Plate 1 Early furnished stamps qualifying as Type Ib -- Positions 3-6R and 8-9R -- distinguished by the complete design at top and nearly complete design at bottom. When first entered on the plate, these six positions (as well as 7R1E) had the complete design at top and bottom. However, unlike 7R, small portions of the bottoms were ironed out when the entries were made below them. Positions 6R and 8R had less of the bottom erased than the other Type Ib positions, and for this reason they are more desirable examples of the type. Position 10R was more extensively ironed out at the bottom, but the entry still retained its characteristic Type I Relief T complete design at top.
