From the photos, I like coin #1 and #2. I would not be comfortable giving one or the other the nod from only photos -- both are very nice from what I can see.
I'm not comfortable with any of those photos. I don't think I would buy #3 based on what I see. The first 2 look nice, but it's hard to tell. If I had to buy one of these, but I would get one of the first 2...but I wouldn't buy either without better images.
