Looking at your photos, especially seeing two small die gouges in the last one, I think you may have the CONECA listed 66 SMS DDO-028. A way to tell for sure I believe would be to see if your half has the listed marker, light die scratch south west of the lower lip, or the very light CW rotation on the I and B of LIBERTY. See photos attached from the DDO-028 in my collection.
