The bands probably look more complete with a different angle of light. 1937 isn't a particular bad date for strike, but not an exceptionally good one. TPGs usually will give the FB designation to a dime with a bare split like this unless it's a date known for being well struck consistently.
It might make 66, because the fields are pretty clear, but I'd call it 65 with the marks on the face.
