The second set of photos look better. I am finding that grading modern Jefferson's is very subjective from year to year. I am working on the 60's and 70's now and there seems to be much more tolerance for die related issues and bag marks for these decades.
Your obverse strike quality is really strong. The reverse looks really good too strike wise. Based on the new photos you posted I would be happy with the MS65. It's a really nice example for a seventies Jefferson.
FS - well, I'm not surprised NGC gave it. The strike is so strong that they forgave the bag marks. I'm just a purest and would try and find one without them. That being said, the price would be much higher than $19!!! Probably double or higher without the bag marks on the stairs.
