Unfortunately this is a sign that the repros have killed the market on Loryn. Every time I look at these signs I see repros selling for twice the price of an original, which is sad. I will go down your list and give my thoughts on each one. Repro, repro, real, real, and as far as I can tell the pair look real to me as well, but the pics in that listing are pretty poor.
I will share with you the two hints I read on here years ago, and that I go by to tell a real sign from a repro as it has not failed me. The first sign of a reproduction is the sign has grommets. I have yet to see an original with them. The second thing to look at is the corners of the sign. The reproductions have sharper, pointed corners. On an original sign the corners will follow the countour of a half dollar coin perfectly. I know this doesn't help with a sign on Ebay, but will when you find one in person. It's pretty easy to see the pointy corners on repros in photos though.
These two hints will help you find an original sign. When this topic has been discussed before, there was some back and forth on the "grommet rule" but I'm just sharing what works for me, and what I look for to make a comfortable purchase, so take it how one wants to.
Good luck, hope you find one you're comfortable purchasing.
Here is a photo of the half dollar in the corner....
