EXTREMELY FINE. A SUPERB MINT NEVER-HINGED GUIDE LINE PAIR OF SCOTT 453 IN THE FINEST CONDITION ATTAINABLE.
The Type I rotary press stamps were produced using the same master dies as had been used for flat plate printings. However, due to the curve of the plate to fit the rotary press, the impressions lacked some of the details of the flat plate printings. This printing process made it very difficult for well-centered examples to be produced. New dies were made with strengthened lines, resulting in the Type II stamps.
