77-D Lincoln MM Question ?

I realize mint marks can be all over the place
but was curious if fairly normal on the 77-D
for the MM to have these attributes.
Low, Left positions, CW rotation, along with the mark
being about 3/4's the size of a normal looking D ? unless that is the norm. on that yr. naturally.
I checked around and found nothing so maybe it is nothing !
will post a pic. if it is something.
that didn't sound right ?
if anyone has a pic. of a few 77-D's please post.
There, that's better.
