Fair price for upper and lower tailgates

[KSmith8849]

I converted my 72 Burb to barn doors several years ago and I have a guy that is interested in my upper and lower tailgate because he has barn doors and wants to convert to tailgate. (To bad he wasn't around several years ago) Anyway the lower tailgate is cherry and the upper would be except for being rusted through on the bottom right inside an area of about 2"x4". He took a photo to talk to his body guy about. He is going to get back with me after he talks to him. Anyway my question is what would be a fair price for them. It does have good glass in it. I am not looking to rob the guy but would like a fair price if I am going to part with them.
