No. The D is plainly visible, therefore not considered weak. The "Weak D" coins look like "No D" at first glance.
I'll see if I can find mine & take a picture. But, it should make you say: Is there, or isn't there (a mint mark).
I have one I have one that looks like a weak D but checked the die markers and found it not so, and another that's pretty worn with no D I have yet to verify. When I get time I'll post pics of each if anyones's interested.
