EXTREMELY FINE. A BEAUTIFUL MINT NEVER-HINGED BLOCK OF TWELVE OF THE 5-CENT ROSE PERF 10 ERROR, SCOTT 467.
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 30c Perf 10 Unwatermarked, Scott 476A, has no trace of the single-line watermark. Although one or two stamps from the discovery sheets have been found with "ghost" watermarks, the Scott Catalogue and The Philatelic Foundation continue to recognize Scott 476A.
