PCGS' Photograde product -- in my experience -- is utterly useless for MS grades. Most of the features that one must take into account for MS60-70 (such as bag marks, hairlines, luster, etc.) can't properly be reproduced from a low-resolution head-on shot of the coin, and their toned examples only fluster and confuse people who are newer to the hobby as the place them in "most toned" to "least toned" order. (It took me years to understand that toning is like how "Hispanic" isn't a race in the Census, it's an ethnicity; toning is an attribute, not part of the grade so you can have toning on an MS70, and it's still an MS70 -- not a perfect metaphor I admit, but I have yet to find a better one. :-) )
However, their examples of the circulated portion of the Sheldon Scale (1-58) are certainly much better and more indicative of what you will see.
Finally, I concur with clairhardesty, that Kennedy looks either very high AU or low MS.
