Interesting. Details seem weak and mushy, but maybe the picture is a bit blurred. It looks a bit beat up too, but that is common with these. My 1839-O looks beat up as well. I'm wondering if it was struck with a really worn die. The relief of the eagle seems pretty high as in a decent strike, but there are no details in the neck. It might make an XF-40 if the lack of detail is due to strike or die issues.
