The white straight line appear to be die polish lines and there is a grove that could be a scratch or planchet flaw.
If the grove is scratch, the coin could grade details. If the grove is a planchet flaw, it should not effect the grade, but could lower the value of the coin because it is on the cheek. If the white lines are die polish lines, it will not effect the grade.
Below is a close up photo of a Morgan with die polish lines and a planchet flaw.
