Here's a 1909 DDR, of which die I cannot identify based on the photos. The extra thickness is tough to pick up in photos but if you look at the tips of the wheats you can see the angles of the light is slightly off and reflects the doubling. Additionally, minor extra thickness is present on the wheat stems and EPL.
