I think you have some die doubling and MDD as well on your half. I think using the doubling on the E of WE is good indicator for the 72D DDO-001, also a couple of good markers that I have on the two DDO-001's from my collection would be the die scratch north-south above the mintmark on the obverse and the north-south die scratch top left of the 3rd ray of the reverse, see photos.
Note: I think what you show on the profile of your half dollar would be MDD, and the photo from Wexler's site is misleading and looks like MDD also to me. My examples of the 72D DDO-001 don't show any doubling on the profile at all.
