De La Rue 5¢ blue die proof on glazed card CSA Catalog 6P1 measuring 93 x 61 mm with characteristic bronzed edges. Scott Catalogue calls this “light blue” which is the color of the CSA 6 stamp, but the stamps are clearly a straight-up blue to my eye and not the stamp shade. The CSA Catalog defines the color as blue and values it at $2,500 while SCV is $600. The true value is somewhere in between, IMHO. $750.
