How about some more shots with magnification between that of your first two pictures and the latter two? To much optical noise and aberration in the latter two. They look more like candy than a part of the overall coin!
Ha, it's DDO-001 . The mint-mark goes with it too . http://varietyvista.com/01a LC Doubled Dies Vol 1/1915DDDO001.htm
Here's another image of the date and mint-mark . I shot this one blind too . Now that I have images to match up too, after dinner I'll re-shoot that position .
Better. Still under the max file size and less pixelated than the others. About 1.5M expanded and room to squeeze in about 500,000 more pixels for crisper detail and higher clarity.
Umm, are you saying this is ddo#1? It isn't. The horizontal of the L of Liberty may be a bit thick but is not doubled. Also the mintmark on your coin is too far east to match the mm position of ddo#1. That said the top serif of the mm does look interesting on your coin from your pics.
