That one is tough to grade, it has a halo effect of luster looks mint but handled? Maybe someone tryed electrolysis on it? Notice afew green spots. Maybe this would be one of those ICCS ms60 grades with no comment.
There looks like disruption of the luster behind King V's head. The halo suggests light circulation. There is a loss of luster on the cheek and lower bands of the crown. I could see ICCS AU-58 or MS-60-ish.
