The KGV 1d rough paper shades can be harder to identify than smooth paper.One reason being they were all printed within a short period , December 1916 to August 1918, & a lot were not used until the 1920's as many were inferior printings & therefore set aside & punctured OS.So date stamps are not conclusive to a particular shade , when the stamp is puncured OS. As most shade collectors know, there are quiet a few sub shades that are found only in OS, and 1 whole group, G78.
Also the quality of print is quiet often patchy, due to the rough paper, so there is a lot of white in the print, which makes identification more difficult.
