Are these from the bottom of the boxes?

Yes they are, collectors had to cut them out from the factory box. they also did this for the second series the Morgan /Bench. Thus the NO number or hologram of any sort. I guess if you bought a case of boxes you had a chance to get most of them. Maybe there is a whole market out there for empty boxes from cards. I personally use them to label-decorate my sets that are stored in albums.
