ID Help?

Hey all! I'm new to this subreddit and I was hoping for some advice. I got my fitst AG Doll about 10ish years ago now, and once I started working st a local thrift store I would pick up a few other dolls and clothing. These are 4 dolls that I had picked up over the years (had them in my possession for 5ish years?) I know for a fact the red head is a knock off, I believe My Generation? I was convinced they're all knockoffs but when I used Google Lens on the blonde it honestly appears as though she may be an authentic AG Doll? I'm moving at the end of March and trying to sell a bunch of stuff I don't feel the need to bring with me, and while I don't wanna rip someone off I hope y'all can understand that I don't wanna get ripped off either 😅 She came with a full outfit and a doll stand (hence the rust marks on her body) and she has the tie strings on the back like the one I got at an AG store has. I'd love some advice on pricing as well as how to identify an authentic AG doll vs the knock offs, aside from obvious factors.
