Ruger 77 458 Stock Value?

[Black Fly]

I bought this stock on another forum a couple years ago. The pictures were ANIB. I paid top dollar for that, got this. Seller disappeared, no surprise.There are cracks as I've got marked and the chip out of the tang and some scratches. It is black walnut and has the steel lug plate. I want to list it in the classifieds. With a little epoxy, maybe a pin or two and some effort, it would make a good beater stock for 458 tanger. I have no concept of a fair price. I appreciate any help.
Thanks
