1985 Jordan Chicago 1 Legit Check

Hey NikeTalk, I am new to this forum so I apologize for any formatting issues. There are a pair of what looks to be 1985 Chicago 1s in my area for a very good price. The lady says they were owned by her grandpa, and just received them in a box of his things. I was curious if these are actually OG 1s. Thank you for your help

The date says that their og's but I never seen a pair from 85 without the leather cracking

Did you buy and if so hm?
