This pane features many Extremely Fine Gems
EXTREMELY FINE GEM. THIS IS ONE OF THE FINEST ORIGINAL-GUM EXAMPLES OF THE RARE 4-CENT COLUMBIAN ERROR OF COLOR.
The 4c Columbian color error was caused by the use of a wrong batch of ink, and spectrographic analysis has shown that the blue inks of the 4c error and 1c Columbian have the same components. There are two slightly different shades of the 4c error, this being the deeper of the two.
Stamps from at least two panes reached collectors, and the few cancelled examples indicate that stamps used by the public came from other panes. It is likely that a number of full sheets were printed using the wrong ink, and most of the stamps have simply been lost to philately.
A significant number of the 4c error stamps extant have faults, poor centering and/or heavy hinge remnants. The examples that periodically appear at auction rarely grade better than Very Fine. This extraordinary stamp is Extremely Fine and has unusually clean gum. It is certainly among the finest known examples of this classic commemorative error.
With 1962 and 1998 P.F. certificates.
