I enjoy looking at coins that have so much luster that you can tell they were hard to photograph. I'll go MS65.
I gotta tell ya, I think Greg's photos are actually emphasizing the flaws on some of your coins. I was two grades low on both of the Walkers that you showed. I am having a really hard time interpreting the grades from his photos. It isn't that I don't like them, I just wonder if they are accurately portraying the surfaces of the coin.
