    1974S Mintmark styles question

    I am trying to figure out what the two MMs are on a whole bunch of '74S Lincolns I have. Picture 1 below has a '74S and '71S - both appear to be MMS-008 "Tall."

    What has me puzzled is the other S I have found. In picture 2, I thought the other MM was MMS-009 "Double Punch" but after I placed it next to a '75S Proof MMS-009 in Photoshop I don't know. I placed a '74S MMS-008 below in the same illustration for comparison. This other S has a different shape - I am baffled...
