1916-D raw floating around in my loose penny box. I'm just getting around to searching and starting conservation.
I agree with the XF for sharpness. I can't see the pictures on my phone well enough for the details Kirk mentions.
The 1914D appears original-ish, and may be worth grading. The grade on that one is limited to F, however - the lines on the wheat ears need to be full to get VF. Even still, a 14D in F-15 is worth $250 or so. The 16D has definitely been cleaned or polished. I like it best at VF details, but I've seen EF's with that level of wear. This coin is only worth a couple of dollars, and is obviously not worth grading.
