25c Yellow Green, Imperforate Horizontally (568b). Block of four with right selvage and plate no. 14063, lightly hinged, bright color

EXTREMELY FINE. THE UNIQUE PLATE NUMBER BLOCK OF THE HORIZONTALLY IMPERFORATE 1922 25-CENT NIAGARA FALLS ISSUE. ONE OF THE GREAT 20TH CENTURY RARITIES.

According to United States Stamps 1922-26 by Gary Griffith, this error was discovered in 1927 in Georgia. In Mekeel's Weekly Stamp News, Sep. 5, 1927, noted dealer Philip H. Ward stated that "the pane was normal with this small corner receiving the vertical perforation only", indicating that only part of the pane contained the error. Auction records seem to support this -- we have only offered a strip of three and a single since keeping computerized records.

Ex Lilly. With 1980 P.F. certificate. Scott Retail $6,500.00 as two pairs with no premium for the multiple or for the unique plate position.
