I see lots of chatter, and the surfaces appear to have the slightest wear. I'm horrible at grading Ikes from pictures, but I'm going to guess AU58.
I see hints of what COULD be wear, but I can't really tell unless I had it in had. Because of this I'm disregarding an AU grade and I'm going with MS-63

I'll say AU-58 , but if they gave it a market acceptable pass I'll say MS-63 . But I'll stick with AU-58 as there's too many circulation hits in the fields .
Your example doesn't seem to have anywhere near the planchet marks this one does. However, outside of the planchet marks (which don't count against grade), the example from jms has nice clear fields with nice luster. Yours looks to have more bag marks thus lower grade IMO.
