Hancock and Moore Leather Desk Chair Value

I have a H&M leather desk chair that I bought new in the mid '80's that I'm interested in selling, but have no idea what it's worth. I've attached a couple of pictures. A few blemishes in the leather, a repaired cracked wooden cover of a caster arm, and recently the cushion and seat were re-stuffed. Any suggestions on a purchase price?
Thanks.Attachment 2855

A 25-year-old desk chair is hard to place a valuation on. It appears to be in remarkably good shape for its age as most office chairs don't last that long. I would say $ 100 to $ 500 as a range depending on the buyer, your location and how well it presents in person.

Thanks for the help.
