I think I see MD in pics 1 & 2. 1923 DDO is not a recognized variety as far as I know. I enjoy utilizing http://lincolncentresource.com The site is well organized for quick reference, and fairly comprehensive.
Iam not sure if linconcent resources has wheat cents!But looK @COPPERCOINS.COM 1923p ddo 001.now i see them there but nothing about a 1923. ITS not in the top 50
1923 DDO is also not listed in cherry pickers guide, either. The site you cited displays code errors for me and is difficult to navigate. Good luck coming to conclusion on this coin, I'm sure others will chime in with their opinions.
