Nice coin. When I look at a couple of guides, I noticed that references to doubling were with obvious doubling in the "IN GOD WE TRUST" and the number 2. Of course guides seem to use high end UNC/MS coins!
Being no expert either, it seems like your strongest case for DDO is in the "IN GOD WE TRUST" and not the date. CONECA has at least 9 variants for a 1972 P among these letters but I am not sure how some wear and its flattening of the letters impacts a variant designation. Good luck!
