Probably an AU-50 given the apparent lack of luster in the photos. The grading services might be going higher now because of “grade-flation.” The piece has a lot of detail, but the luster is note showing in the photos.
I was thinking and ready to post exactly the same as @johnmilton . . . I'll stop here. Nice looking coin!
If you see any luster around the coin I am thinking AU53 or AU55. This is another very nice looking coin Eduard.
