5c Carmine, Imperforate, Error (485). Single error in Mint N.H. block of six, bottom center stamp the error, huge margins

EXTREMELY FINE. AN ATTRACTIVE MINT NEVER-HINGED EXAMPLE OF THE 1917 5-CENT CARMINE IMPERFORATE ERROR IN A BLOCK OF SIX.

During the course of production of the normal 2c plate No. 7942, three positions were noted to be defective. The plate was returned to the siderographer, who burnished out the three positions and mistakenly re-entered them using a transfer roll for the 5c stamp. The error passed unnoticed and the sheets were issued to the public in Perf 10, Imperforate and Perf 11 formats (Scott 467, 485 and 505). The imperforate is by far the rarest of the three.

With 2002 P.S.E. certificate. Scott value as single error without premium for the 2c stamps
