May I see a close up of the date I think I see signs of a RPD on the one. As for grade I'm sorry to buck the trend but I think EF45. Its a strong strike with good shield lines so I would not expect the see the level of wear on the leaves or the slight blurring of the horizontal shield lines on an AU coin. I'm sure these days it would get slabbed AU just not in my book.
