The lighting has prevented a strong showing of the lustre; perhaps the same lighting, but at a slightly increased angle, would help show up any little nicks and scratches better as well, or maybe use a single light source. I assume that this coin in fact, has lots of lustre.
Obvious nick near the ear lobe, and a light finger print behind the head. I will be a 'stick in the mud' here and assume more tiny marks which I can't see, but I could very well be wrong. That's why it is good to have the coin in hand.
MS63.
Lotsa '64's were struck and very few of them saw circulation, therefore high grades are easier to find.
