Having seen them in hand, the mark on #1 is simply a streak in the toning. The luster on #2 has more boom than #1, but less rainbow. I'd have a hard time choosing between them.
#1 would be my first choice. It has the best strike and really nice toning. #4 would be my second choice. Still nice color and looks like great luster.
Yes I agree 1 And 2 are to me the best eye appeal . The 38 D needs to be looked at for the rpm. But to pick one I would go with #1
#2 calls to me the most out of 1 & 2. 3 & 4 are 3rd and 4th place for me. The 13-ty2 has a weak strike and too much haze in the toning and the 38-D is fair 'common'.
#2 It has the best strike and luster plus some cool color, especially on the back. I also feel it is under graded and belongs in a 65 holder.
I picked #4, but it really depends on what your goal is. I think better struck 1913 type 1 and 2's are available. Just my opinion.
