The 1871 3d was the progenitor of all subsequent DLR plates. The dies used for all other denominations, ultimately, derive from the 3d.
The 3d stood alone for nearly 20 years. An entire generation of collectors had the Perkins Bacon Recess issues and this ugly duckling (charitably called cinnamon). It was not until 1890, that the PB recess plates were finally replaced with DLR surface printing designs.
The 3d layout was copied for all other plates except for the Key & Duties. Half a century later, this same 3d layout was used for the Kangaroo issues of 1913. This in turn has some bearing on the hows and why's of later federation printings of some of DLR plates.
