EXTREMELY FINE APPEARANCE. A RARE UNUSED EXAMPLE OF THE 1851 ONE-CENT IMPERFORATE TYPE III, WITH CLEAR AND DISTINCT BREAKS IN OUTER LINES AT TOP AND BOTTOM -- THE DEFINING CHARACTERISTIC OF THE TYPE.
Type III is defined by breaks in the outer lines at both top and bottom. Many Type III stamps have breaks that were created or enlarged by plate wear. Since the wear occurred over a period of time, a majority of stamps of this type (both unused and used) have small breaks in at least one line. The most notable exception is Position 99R2, which has the widest breaks of any Type III position, due to the short transfer during plate entry.
