Before collectors, dealers, and third party graders began using all 11 mint state grades, Gem Bu (GBU from your first post) was usually considered the equivalent of MS65. At that time, MS65 was a pristine coin with very few marks. I don't honestly see any of these coins as MS65, even by today's more relaxed standards. Most would be MS63 or below, in my opinion. Other members may have a different opinion.
That is not to say that I don't like them, though. I have always had a thing for commemoratives, even though I only have a few in my collection.
By the way, judging by the pictures, I don't think that any of these, or the gold commems from your other post, have been polished.
