CSA #12 -- 10c Blue -- Jefferson Davis -- Line-Engraved

Distinguished from CSA #11 most prominently by the filled-in corners at bottom left and right. Need to have the stamp in hand and a magnifier to distinguish the Archer & Daly printings from the Keatinge & Ball printings. For a detailed explanation of how to tell the difference between an Archer & Daly printing and a Keatinge & Ball printing, CLICK HERE.

19. Miscellaneous Data: The plates for the A&D stamps were transferred to Columbia SC when the fall of Richmond became evident in late 1864. Printing of the stamps ceased on 17 February 1865 when Sherman's Army captured Columbia SC. Many full sheets remained at the end of the war. The major characteristics distinguishing the K&B printings from the A&D printings are 1) the ink was applied to the K&B stamps with a very heavy brush and the ink tends to blot out the background details such that the shading around the portrait appears solid instead of cross-hatched, 2) a distinctive heavy thick brown-yellow gum was used on the K&B stamps, 3) the K&B stamps tend to be of a uniform dark blue color (although some color variation does exist).
