The D's are few and far betwixt, but go through hundreds if not thousands of boxes like I have and they do add up after awhile. The P's are most common of course, followed by the S and way down the road are the Ds. Early date Jeffs are the one rare exception to preferring the D mm vs. the S. I have found about a dozen '39-D's over the years and a lot more '38-Ds. Only two '50-Ds in all those coins searched.
I was thinking back to my CRH days, I think I was finding one silver every box and a half. So 2 for three boxes searched. Most were Philly being here in the east, so location played a factor.
