These look authentic to me.
The swoosh shape is good. The wings logo look right. The 'Nike Air' text on the tongue looks correct and so does the text in the back.
The numbers and text on the bottom of the tag should be there on all pairs. I don't know how long they have been doing this for, but my Jordan 1's from 2013 have it, the first remastered Jordan 1 which was Fragment's had it, and every other Jordan 1 High OG since then does have it. You might not have noticed it before because the factories usually sew the tag too low were you cant lift it up to see the text underneath.
If you can, add pictures of the 'Nike Air' on the insoles and bottom soles, the box label, pictures of the back of the shoe, and included photos of the right shoe as well.
