I have no idea on the grade, as I do not know Washington quarters, but what is Type B as compared to Type A(I presume)?
Type B quarters come into play with 1956-64 Philadelphia minted quarters. Type A is the normal reverse...Type B are coin minted using the proof reverse die. There are several specific die markers that distinguish the Type B coins. Here is a link to a page with images that show the Type B die markers. http://boards.collectors-society.com/ubbthreads.php?ubb=showflat&Number=3707283
Maybe the lighting makes the hit on the cheek look worse than it really is. I'm thinking 63 but might go higher if I saw it in person. I'll bet the luster is outstanding.
~MS63. I wonder if the NGC/PCGS have a good technique / variable lighting to see-through toning, or they just wing it. Some bag mark scuffs / hits could definately be hidden by deep toning.
