The '27 is one of those coins where you can ask ten people and you'll get 15 different answers - everyone seems to look for different things to grade them (even ignoring the steps).
The toning with the light angle makes it hard to see how much fine detail is there on the obverse so it's hard to give a fair assessment of that.
From what I can see, the closest one I have to this I graded as G/nEF
