There appears to be plenty of even wear throughout. I'm not sure how to look at the edges, as these Japanese 1 Shu coins have all different cuts and sizes. The vertical streaks are supposed to be there. And, despite the photo quality, what would be your best educated guess as to its grade? Should I look for a better example, like the second one? What grade do you think that one should be? The strike looks to be better, less wear, less tarnished appearance... either can be cleaned though. Not sure. Thanks in advance!
