FWIW, I have 1936-, 1937-PDS, 1938-PDS, 1939-PDS, 1940-PDS all certified MS67 red and NONE of them have any beard details.
I will say an Ms65 seems to be limited marks on the coin has good eye appeal nice strike, and some toning. a nice looking coin I guess in hand it could be a MS 66. Jazzcoins Joe:whistle:
I most definitely is there and, IMHO, will absolutely affect the grading. Even Phoenix found it after I pointed it out.
