A sharper hi-res shot of the date & MM could lend support to my guess of it being primarily MD.
It will be interesting to see what that little protrusion is under the top loop of the 3 in the first photo. That small object, however, at first glance does not appear to be MD.
It most likely is not a hybrid DDO/MD but I have seen verified examples of these in a 1969-S cent that still fetched a pretty penny.
